Karnataka Water Resources Department (Cauvery Neeravari Nigam Limited)

Prepared by

Chief Engineer, Irrigation South Zone,

Emergency Action Plan for KRISHNARAJASAGARA (KRS) DAM [KA06HH0020] version 2.0

KRISHNARAJASAGARA DAM

Project ID Code [KA06HH0020]

Mandya, Karnataka

DISCLAIMER

Every effort has been taken to estimate the severity of flooding and inundation areas likely to be

affected by Krishnarajasagara Dam in an emergency condition. These estimates are based on available

primary and secondary data. Every effort has been made to foresee varied emergency possibilities and

develop appropriate notification procedures for timely rescue and relief operations. However,

implementation of the Emergency Action Plan (EAP) involves many agencies, who are required to work

in a coordinated manner to reduce the consequences of the emergency triggered by the dam site

condition. Effectiveness of the rescue and relief operations depend on many factors including the

adequacy and accuracy of the estimation of the severity of flooding, coordinated efforts of all the

agencies involved in rescue and relief efforts and availability of facilities like power, telephones, road

communications, etc. EAP developer may therefore, not be held responsible for the efficacy of the EAP.

1. PURPOSE

The purpose of this Emergency Action Plan (EAP) is to identify emergency situations that could threaten

Krishnarajasagara Dam [KA06HH0020] and to plan for an expedited, effective response to prevent

failure of the dam and warn downstream residents of impending danger. This plan defines the

notification procedures to be followed in the event of a potentially hazardous situation. The procedures

are intended to protect lives and prevent property damage from an excessive release of water from the

dam spillway or an uncontrolled outflow of water from the breached portion of the dam.

2. DAM DESCRIPTION

2.1 General

Krishnarajasagara Dam and Reservoir are owned and operated by Cauvery Neeravari Nigam Limited

(CNNL) under Karnataka Water Resources Department. The reservoir is constructed on Cauvery river in

Mandya district, approximately 15 Kms upstream of the historic town of Sriangapattana, 45 km

southwest of Mandya city and 20 km northwest of Mysuru city, Karnataka. The dam is constructed below

the confluence of river Cauvery with its two tributaries, the Hemavathy and the Lakshmanathirtha. The

construction of dam was commenced in 1911 and completed in 1931. The reservoir was constructed to

serve for multiple purposes.

The catchment area of the river above the dam is 10619 square kms and lies in the region which receives an

annual precipitation of 635 cms (250 inches) in the western ghat portion having an area of 4871.79 Sq.Kms

and 71.12 cms. (28 inches) to 101.6 cms (40 inches) in the plain areas having an area of 5747.21 Sq.Kms.

The flow of the river at the site of the dam fluctuates from a normal high flood of 2831.66 Cumecs (1,00,000

cusecs) during the monsoon season to a low flow of 2.83 cumecs (100 cusecs) during summer. The highest

flood occurred in river is in the year 1924 which was 8210.65 Cumecs (2,90,000 Cusecs).

The dam is 2621 metres (860 feet) long and 39.62 metres (130 feet) high above the river bed and is intended

to store 37.79 meters (124 feet) depth of water at full reservoir level (Figure 1). The height above the

deepest foundation is 42.672 meters (140 feet). The live storage capacity of the reservoir is 1244.06 MCM.

(43.934 TMC) above the cill of the irrigation supply sluices which are at 18.29 meters (60 ft.) above bed level

and the gross storage capacity is 1368 68 MCM. (48.335 TMC). A motorable roadway of 4.42 metres wide is

formed on top of the dam with ornamental parapets on both side with electric lights.

There are in all 173 sluices in the dam, of different sizes at various levels provided for 1. flood disposal

and scouring, 2. irrigation and 3. power generation.The flood disposal and scouring sluices comprises of

a) 40 vents of 2.44 metre (8 feet) X 3.66 metre (12 feet) at cill level of 32.31 metre (106 ft.) above bed

level is situated immediately after the entrance gate at the south end. These are provided with lift

gates which operates electrically by a travelling crane.



Figure 1 : General Layout of Krishnarajasagara Dam

b) 48 vents measuring 3 meter (10 feet) X 2.44 meter (8 feet) at cill level 31.39 meters (103 ft.) above

bed level are provided with lift gates operates electrically by another travelling crane. c) 48 vents of 3 metre (10 feet) X 3 meter (10 feet) at cill level of 34.75 meter (114 feet) above bed

level provided with automatic gates with six batteries each. These gates were designed to operate

automatically when water level reaches 37.8 metre (124 feet) and close automatically when it falls

below that level. As per the available old records, these gates were operated by lifting with the help

of cranes d) 16 sluices of 3 meter (10 feet) X 6 meter (20 feet) at cill level of 24.38 meter (80 feet) above bed

level, each provided with a gate operated electrically by an independent crab winch. e) 8 deep level scouring sluices of 1.83 meter (6 feet) X 3.66 meter (12 feet) at cill level of 3.66 meter

(12 feet) above bed level are provided at the center of the dam i.e., at the original river course.

These gates operate mechanically by independent crab winches.



f) 3 scouring sluices of 1.83 meter (6 feet) X 4.57 meter (15 feet) at cill level of 15.24 meter (50 feet)

above bed level on the north bank of the river operates mechanically by independent crab winches.

The maximum discharge which can be passed through all the above sluices is 9910.8 cumecs (3,50,000

cusecs). The surplus water is released through suitable waste weir channels with necessary protective

works.

The irrigation sluices comprise of;

a. 3 vents of 1.83 meters (6 feet) X 3.66 meter (12 feet) at cill level of 18.29 meters (60 feet) above

bed level is situated on the north bank of the river to feed the North Bank High Level Canal known

as the Visvesvaraya Canal which is irrigating 77,193 Ha (1,90,753 acres) and also a Right Bank

Low Level Channel having command area of 579 hectares (1430 acres). These irrigation sluice

gates operate independently mechanically by crab winches. b. 1 vent of 1.83 meters (6 feet) X 2.44 meter (8 feet) at cill level of 18.29 meter (60 feet) above bed is

located at the south end of the Dam. The Right Bank Low Level Channel takes off from this vent

emerging through a tunnel immediately below the entrance gate of the Dam. This channel is

designed to irrigate an area of 1533 Ha (3789 acres). These irrigation sluice gates operate

independently mechanically by crab winches. c. 1 vent of 2 gates each of 3.5 meters (11.5 feet) X 3.5 meter (11.5 feet) size at cill level of 18.29

meter (60 feet) above bed is located at the south end of the dam known as DD Urs Canal (Varuna

Canal ) is the Right Bank High level Canal of Krishnarajasagara Dam takes off through a tunnel of

135 m length. It runs for a length of 126.50 kms with carrying capacity of 980 cusecs to irrigate

command area of 31728 Ha (78400 acres).

The power generation sluice comprises of;

a) Turbine sluices consisting of four pen-stock pipes of 1.83 meter (6 feet) diameter with centers fixed

at 16.15 meter (53 feet) above bed.

A vicinity map showing the location of the Krishnarajasagara dam is presented in ANNEXURE 1 :

VICINITY MAP and its salient features are summarized in ANNEXURE 16 : DAM DESCRIPTION. Inundation

maps showing the areas subject to flooding as a result of a dam failure along with other recurrent flood

scenarios are provided in the ANNEXURE 10 : INUNDATION MAPS of this document.

2.2 Reservoir Operations

Krishnarajasagara dam though conceived as multi-purpose project with an emphasis on irrigation and

hydropower generation, due to increase in habitats in the downstream areas, flood control is also

considered as one of the important purposes of the project. Flood forecasting of Krishnarajasagara dam

is done by observing the rise in the water level of the river with respect to a gauge post established at

the Chunchanakatte for Cauvery river, at Akkihebbal for Hemavathy river and at Hundavadi for



Lakshmanatheertha river on the upstream side of the reservoir. By observing the hourly reservoir level,

the flood is calculated and gates are operated accordingly to release the flood water and to maintain the

safe water level in the reservoir. A gate operating schedule and sequence of opening and closing of the

gates and methodology of regulation of flood is prepared and the scheduled is followed.

2.3 Gate Operations Schedule for +80Ft level Surplus Sluices

In case of notch flow, the discharge (Q) through each gate is given by Q=Lh1.5C√(2g), h is the head

measured from the crest level of the spillway up to the reservoir water level below RL+102’. In case of

Orifice Flow, the discharge (Q) through each gate is given by Q=C*A√(2gh), h is the head measured

from the centre of the orifice opening up to the reservoir water level above RL+102’. Basic Values of

C√(2g) is taken from the Book titled “Krishnarajasagara Dam Sluices” authored By Shri. M C Sampath

Iyengar - 1948. Discharge coefficients (C) for notch flow through +80‘level surplus sluices of K R Sagara

dam up to RL +102’ recommended in the Book are considered in computation of Discharge using the

equation Q=C√ (2g) LH1.5 where H= head over the crest, L = length of Spillway; =10’

2.4 Gate Operations Schedule for +103ft level Surplus Sluices

In case of Notch Flow the discharge (Q) through each gate is given by Q=Lh1.5C√(2g), h is the head

measured from the crest level of the spillway up to the reservoir water level below RL+112.3’. Value of

C√(2g) =3.02 for all levels up to RL +112.3’ for notch Flow. In case of Orifice Flow, the discharge (Q)

through each gate is given by Q=C*A√(2gh), h is the head measured from the centre of the orifice

opening up to the reservoir water level above RL+112.3 ft. Basic Values of C√(2g) is taken from the

Book titled “Krishnarajasagara Dam Sluices” authored By Shri. M C Sampath Iyengar -1948.

2.7 Rule Curve of Reservoir Operations

The Krishnarajasagara reservoir rule curve is developed month vs storage capacity and month vs

reservoir level for the Full Reservoir Level of 124.80 feet (752.32) and same is shown below;

Figure 10 : Rule Curve of Krishnarajasagara Dam

Table 13 : Upper Limit and Lower Limit of Reservoir Operations Rule Curve for Krishnarajasagara Dam

2.8 Operation of Gates when reservoir level range from +122 ft to +124 ft

+80ft sluice gates are operated either fully or partially but operate all other gates only for full opening of

vents and never open the gates partially. Operate the +80ft, +103ft, +106ft and +114 ft gates which are

automatic in the same manner when the reservoir levels are ranging from +92ft upto +122ft.

2.9 Operation of Gates when reservoir level during excess flood

Water level in the lake is not allowed to rise above +123ft when the flood is rising and exceeds one lakh

cusecs in the months of July and August, which is peak monsoon period in the Cauvery river basin,

Impounding of water in the reservoir from +123ft to +124ft is when the flood begins to fall and inflow is

less than one lakh cusecs.



Reservoir level is reduced to +123ft when the reservoir is full or nearly full when the flood exceeding one

lakh is observed and full reservoir level +124ft is attained when the flood recedes below one lakh cusecs.

Opening of the +50ft sluice gates for full height when the intensity of the flood is seen to rise above 2½

lakh cusecs and in addition, +12ft sluice gates are also opened when the intensity of flood further

increases above three lakhs cusecs.

2.10 Sequence of Opening or Closing of Gates

During the time of discharge, vertical surplus sluice gates shall be opened to release the flood in the

following sequence. Out of 156 flood gates, initially 40 numbers of +106’ level gates are operated through

gantry crane alternately.The sequence of Gate No’s are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30,

32, 34, 36, 38, 40 from ‘0’ M chainage to ‘160’ & 39, 37, 35, 33, 31, 29, 27, 25, 23, 21, 19, 17, 15, 13,

11, 9, 7, 5, 3, 1 and vice-versa.

Secondly flood shall be released through 48 numbers of +103’ level gates operated through crane (lifting

mechanism) alternately. The sequence of Gate No’s are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28,

30, 32, 34, 36, 38, 40, 42, 44, 46, 48 from ‘160’ M chainiage to ‘370’ M & 47, 45, 43, 41,39, 37, 35, 33,

31, 29, 27, 25, 23, 21, 19, 17, 15, 13, 11, 9, 7, 5, 3, 1 and vice-versa.

Thirdly excess flood shall be released through 16 numbers of +80’ level gates to be operated individually

by electric motor. The sequence of Gate No’s are Gate No 16 & Gate No 1, Gate No 15 & Gate No 2, Gate No 14 & Gate No 3, Gate No 13 & Gate No 4. Gate No 12 & Gate No 5, Gate No 11 & Gate No 6,

Gate No 10 & Gate No 7, Gate No 9 & Gate No 8.

5. EMERGENCY DETECTION, EVALUATION AND CLASSIFICATION

5.1 Emergency Detection

5.1.1 Situations

Many dam conditions can lead to emergency situations, not all of which will require the implementation

of the EAP. However, if any of them occur, the appropriate actions must be taken. ANNEXURE 12 :

EMERGENCY LEVEL DETERMINATION – ACTION DATA SHEET INDEX of this EAP shows that most

common emergency situations that may emerge in Krishnarajasagara dam and appurtenances, along

with the corresponding specific actions to be done by each of the dam’s officials. Some of these

emergency situations are as follows:

▪ Severe Storms / Inclement Weather: Although generally not in themselves a threat to the dam,

severe storms and other inclement weather conditions can contribute to an existing problem and

hinder any remediation efforts. Severe storms also cause the uncontrolled release of floodwater and

increase flow in already rain-swollen areas.



▪ Tropical Cyclones: Tropical cyclones do occur in the area, with the potential for structural damage to

the dam, possibly resulting in its failure. If a tropical cyclone has stuck in the area, an inspection of

the dam for any signs of damage will be appropriate. ▪ Earthquakes: Krishnarajasagara dam is located in the Seismic Zone II. This zone is classified as

Low Damage Risk Zone which is liable to MSK VI or less. The IS Code assigns zone factor of 0.10

(maximum horizontal acceleration that can be experienced by a structure in this zone is 10% of

gravitational acceleration). However, appropriate post-earthquake inspections should be performed. ▪ Sabotage: A threat to damage that has been made. Appropriate actions must be taken to protect the

dam.

5.1.2 Signs of Failure

Site Engineers in coordination with the Executive Engineer are responsible for conducting routine

inspections and identifying conditions that could indicate the onset of problems leading to a dam failure. The

early identification of potentially dangerous conditions can allow time for the implementation of the EAP. The

following section describe some of the different types of failure which could lead to a dam failure.

▪ Foundation Sliding: Sliding is usually first apparent when cracks appear. Slides with progressive

movement can cause failure of the embankment. ▪ Structural Failure: The structural failure or collapse of any non-overflow portion of the dam, spillway

or spillway gates could result in loss of the reservoir. A structural failure of a portion of the spillway

could cause piping and possibly embankment failure. ▪ Overtopping Failure: Overtopping of the embankment results in erosion of the dam crest. Once

erosion begins, it is very difficult to stop. ▪ Piping Failure: Piping in the body of the dam is also results in failure of the dam. However, failure of

dam can be avoided if early noticing and rectifying the piping is carried out.

5.2 Emergency Evaluation and Classification

This section lists the conditions and actions which may be used to classify the level of emergency

response, as a guide for The Emergency Planning Manager (Executive Engineer, KRS Division).

Specific dam observations and corresponding emergency classification levels can be found in

Annexure-12 along with appropriate and recommended actions to follow in each case.

Internal Alert Condition (BLUE) – A Watch condition – A problem has been detected at the dam that

requires constant monitoring. At this time, the distress condition is manageable by dam personnel. The

Emergency Planning Manager (Executive Engineer, KRS Division) along with the support of site

engineers will be responsible for monitoring and repaid as soon as possible and implementing the

appropriate Notification Flowchart. The following is a list of condition that would initiate the condition:



▪ Cloudy or dirty seepage or seepage with an increase in flow, boils, piping or bogs ▪ Cracking or movement of any masonry / concrete structure ▪ An increase in the reservoir level leading to engagement of the flood gates ▪ Exceptionally heavy rainfall in the catchment of the dam

External Alert Condition (ORANGE) –This is indicative of a dam condition that is progressively getting

worse; and there is a high probability of dam failure. Although there is no immediate danger, the dam

could fail if condition continue to deteriorate. The Emergency Planning Manager (Executive

Engineer, KRS Division) will be responsible for initiating immediate repairs, including lowering the

reservoir if appropriate and implementing the appropriate Notification Flowchart. The following is a list of

conditions that would initiate this condition.

▪ Any flood release matching with the flood release capacity of the dam. ▪ Large boils, increasing size and flow rate, especially if there is flowing muddy water. ▪ Significantly increasing seepage, especially flowing muddy water. ▪ Slides involving a large mass of material that impairs the crest of the dam and is continuing to move. ▪ Sinkholes with seepage flowing muddy water. ▪ Large cracks, movement or failure of a portion of any major concrete / masonry structure that forms

an integral part of the dam. ▪ An increase in the reservoir level to near the top of the dam. ▪ Near to ‘Design Flood’ inflow forecast.

External Alert Condition (RED) - These are “failure” conditions – Either the dam is in immediate

danger of failing or has already failed. No time remains to implement measures to prevent the failure

hence evacuate immediately. Evacuation efforts will continue until the situation is stabilized. The

Emergency Planning Manager (Executive Engineer, KRS Division) is responsible for implementing

the appropriate Notification Flowchart. The following is a list of conditions that would initiate “imminent

dam failure” or “dam failure” conditions.

▪ Any flood release higher than the flood releasing capacity of the dam ▪ Rapidly increasing boils of the presence of new, significantly flowing boils, particularly muddy ones

near previously identified ones. ▪ Rapidly increasing seepage, especially flowing muddy water ▪ Slides involving a large mass of material or if significant seepage is observed through the slide area. ▪ Settlement that is predicted to degrade to the reservoir level. ▪ Cracks that extend to the reservoir level. ▪ Significant movement of failure of any structure that forms an integral part of the dam. ▪ Overtopping of the masonry dam.



5.3 Previously Known Problems

▪ Sweating on the downstream face of the dam was observed in the reach Ch. 700m to 1800m when

the reservoir level reaches +100m and above. ▪ Water springs are observed in the downstream area about 8m downstream of the toe of the dam at

Ch. 2160m ▪ Damages occurred to the apron provided downstream of waste weir sluices ▪ The guide wall constructed on the right side of the draft channel of scouring sluices having sill at +50

has been damaged. ▪ The profile of the dam is undulating presenting a look of bulging and depressions on the surface. ▪ Leakages are seen in different portions on the downstream face in the reach from right abutment to

the boating pond. ▪ Lime leaching has occurred on downstream face of the dam ▪ Joints in the masonry have opened sufficiently due to erosion of the pointing material. ▪ The upstream faces generally appear in good condition except in few places below +100 ft near

Visvesvaraya canal.

6. PREPAREDNESS

Preparedness actions are to be taken both before and following the development of emergency

condition and should identify ways of preparing for an emergency, increasing response readiness in a

uniform and coordinated manner and helping to reduce the effects of a dam failure. The following are

some steps that could prevent or delay failure after an emergency is first discovered.

6.1 Surveillance

Round the clock surveillance at the dam and its appurtenant (all along the reservoir) will be carried out by

site engineers during the emergency situations. To ensure that the whole system (including civil structures

& mechanical installation) is being maintained well up to satisfactory level, the repair maintenance must

be carried out by Executive Engineer, Assistant Executive Engineer and Assistant Engineers as per

requirements of O & M manual of Krishnarajasagara Dam. In addition, it must be ensured that

maintenance and upkeep of different components is carried out and will be only possible through

deployment of well procedure conversant and trained staff. The list of such persons should be displayed

on a photo frame mounting at convenient safe place at dam site and list of local telephone numbers

inside the dam & outside the dam area and it will be updated from time to time for any change.

6.2 Response on forecast of excessive inflow

Flood forecasting of Krishnarajasagara dam is done by observing the rise in the water level of the river

with respect to a gauge post established at the Chunchanakatte for Cauvery river, at Akkihebbal for

Hemavathy river and at Hundavadi for Lakshmanatheertha river on the upstream side of the reservoir. KARNATAKA WATER RESOURCES DEPARTMENT 49


By observing the hourly reservoir level, the flood is calculated and gates are operated accordingly to

release the flood water and to maintain the safe water level in the reservoir. A gate operating schedule is

prepared and sequence of opening and closing of the gates and methodology of regulation of flood

described in the gate operating schedule is followed. Trigger level of Alert for Normal Discharges of KR

Sagara Dam listed in Table 14 to be followed in declaring the alert level.

Central Water Commission has established a gauge-discharge site at downstream for assisting in flood

warning in the Cauvery River Basin. Based on the rainfall in the catchment area and flow observed in

the Cauvery river and its tributaries, CWC will furnish flood forecasting reports and trend of flow to the

dam authorities.

6.3 Response during emergency situations

A siren is used for flood warning in Krishnarajasagara Dam. Siren alert will be given to the people

residing in the downstream area of the dam 72 hours before releasing of the flood water from the

reservoir. Flood warning messages are also broadcasted and telecasted through Television and Radios.

Wireless and Mobile phones are also used to transmit the information to the people residing in the

downstream areas of river and evacuation of these people is done if necessary. Responsible officers are

kept in alert round the clock to manage the flood situation. All members of the committee are provided

with wireless and mobile phones for easy access and communication.

6.4 Response during weekends and holidays

The standard Operating Procedure with Reservoir Operation & Maintenance Manual and Gate

Operations Manual are strictly followed throughout the year whether it is weekends / holidays / night.

Executive Engineer, KRS Division will be available for emergency response during weekends and

holidays and can be present at the dam site within 15 minutes of detection of an emergency condition. In

case of non-availability of the Executive Engineer, KRS Division, the Assistant Executive Engineer, Dam

Sub-Division will take his responsibilities.

6.5 Response during periods of darkness and adverse weather

The Executive Engineer (KRS Division) and Site Engineers will arrange for access to generators and

lights to adequacy monitor the situation. Site Engineers will ensure the generation and emergency light

are well maintained and available under any circumstances. The Executive Engineer, KRS Division will

be able to access the site during adverse weather condition by off road vehicle.

6.6 Access to Site

The following accesses to the dam are available and depending on the emergency situations, some of

them should be used with cautions or totally avoided. (See Table 19 and Annexure-1)

6.1 Remedial Actions

Preparedness and remedial actions can be taken in an emergency to prevent the catastrophic failure of

the dam, but such repairs should be undertaken with extreme caution. The repairs are only temporary

and a permanent repair should be designed by an engineer as soon as possible.

Specific actions for different emergency situations are described in the ANNEXURE 12 : EMERGENCY

LEVEL DETERMINATION – ACTION DATA SHEET INDEX. Examples of the actions to be taken for dam’s

officials under the direction of a professional engineer or contractor are described below. In all cases, the

appropriate Notification Flowchart must be implemented and the personnel of the Karnataka Dam Safety

Organization must be notified.

Consider the following remedial actions if the dam’s integrity is threatened by:

Seepage Failure:

▪ Plug the flow with whatever material is available (hay, bentonite or plastic) if the entrance is in the

reservoir. ▪ Consider lowering the water level in the reservoir



▪ Place an inverted filter (a protected layer of sand and gravel) on the exit area to hold the material

in place. ▪ Continue operating at a lower level until a repair is made.

Dam Body or Foundation Failure:

▪ Lower the water level in the reservoir at an elevation considered safe for given slide condition. ▪ Stabilize the slide, if on the downstream slope, by weighting the toe area below the slide with

soil, rock or gravel. ▪ Continue operating at a lower level until a repair is made.

Structural Failure:

▪ Implement temporary measures to protect the damaged structure, such as placing rock riprap in

the damaged area. ▪ Lower the water level to a safe elevation through the low flow outlet.

7. SUPPLIES AND RESOURCES

7.1 Contracts

If Krishnarajasagara project’s personnel and resources prove to be inadequate during an emergency,

requests will be made for assistance from other local jurisdiction, other agencies and industries as needed.

After examining the results of the breach analysis of the Krishnarajasagara dam, it has been determined

that there were a significant number of structures that could be affected due to a large discharge from

the dam or dam breach scenarios. These structures are located along the river Cauvery and its

tributaries such as Lokapavani and Kabini rivers. The most important crossing structures susceptible to

the failure scenario are summarized in Table 21 below and are labelled in the Annexure: 1.

The potential consequences either due to a hypothetical breach scenario of Krishnarajasagara dam or

due to a large controlled release from the spillways (> 10000 m3/sec) involves Mandya, Mysuru,

Chamarajanagar and Ramanagara districts located downstream of the dam. The Villages which can

suffer a significant impact are listed in ANNEXURE 8 : LOCAL EVACUATION PLAN FOR THE AFFECTED

VILLAGES AND SAFE SHELTER ARRANGEMENTS. The most affected areas in a failure scenario are those

located near the river banks where the hydraulic conditions are extreme.

9.1 Local Evacuation Plan

If imminent failure of Krishnarajasagara dam with uncontrolled downstream flooding is anticipated, local

disaster management and law enforcement personnel should notify those downstream villages listed in ANNEXURE 8 : LOCAL EVACUATION PLAN FOR THE AFFECTED VILLAGES AND SAFE SHELTER

ARRANGEMENTS for evacuation in the most expedient manner possible following the procedure given in the

Notification flowchart of this document. Local law enforcement officials along with local mobile network

operators, radio and media representatives can best spread the notice for evacuation. (Responsibilities for

Notification and Responsibilities for Evacuation). In addition, ANNEXURE 12 : EMERGENCY LEVEL

DETERMINATION – ACTION DATA SHEET INDEX can be used as support in the decision-making proves

either to escalate or downgrade an emergency event. The most important actions that should be taken

during an evacuation process are:

▪ Police Departments will barricade all bridges and roads that could possibly be flooded to

prevent access to the affected area. These bridges include all crossings of river Cauvery and its

tributaries downstream of the dam and as well as those affected roads shown in ANNEXURE 1 :

VICINITY MAP. These structures were identified by superimposing the flood inundation maps over

the bridge locations

▪ The Districts Disaster Management Authorities (Deputy Commissioners) will assist with the

notification of all persons and agencies involved (relief authorities) with the possibility of

additional support – including contacting others not accessible by radio or telephone.

▪ Relief Authorities (Police, Fire, Defence) are generally familiar with developed areas in their

jurisdiction. Such knowledge coupled with the requirement of state law that they respond to

disaster make them the logical officials to be notified and to spread the warning message to all

areas subject to flooding.

Based on the specific results of the dam breach analysis (wave arrival time), a complete list of relief

camps (shelters) is included in ANNEXURE 9 : SHELTERS / RELIEF CAMPS AVAILABLE OUTSIDE THE

INUNDATION AREA to provide a safe shelter for evacuated people.

Resources Department, Karnataka and the Chief Engineer of Dam Safety Organization. This plan will be

reviewed and updated annually before the 1st June of every year by the Emergency Planning Manager

(Executive Engineer, KRS Division, KR Sagara) and the Superintending Engineer. This

review will involve corresponding personnel from local disaster management agencies in conjunction

with Dam Safety Organization’s staff.

The Superintending Engineer will organize every year prior to monsoon an orientation meeting to

introduce the revised EAP to local officials, emergency responders. This meeting will give an opportunity

to all the stakeholders to review and comment on EAP document and their respective roles.

The Emergency Planning Manager (Executive Engineer, KRS Division) will review and complete all

items on the Annual EAP Evaluation Checklist in ANNEXURE 15 : ANNUAL EAP EVALUATION CHECKLIST.

After the annual update is complete, a new Approval and Implementation sheet will be attached and the

annual update will be documented on the ANNEXURE 18 : PLAN REVIEW AND UPDATE. If revisions to the

EAP are made as a result of the annual update, such changes will be recorded on the log sheet of changes

form at the front of the report. A copy of the updated portions of the EAP will be sent to all concerned offcials

as per the EAP DISTRIBUTION LIST. If the EAP was reviewed and revisions were not required, The

Emergency Planning Manager (Executive Engineer, KRS Division) will submit written notification to all

concerned that no updates to the EAP have been adopted or implemented.

10.3 Testing

The Superintending Engineer shall organize the following exercise as specified below:

Orientation (Stakeholder’s Consultation): The Superintending Engineer will organize an orientation

meeting every year with local responders and stakeholders to solicit input, established roles during

emergency situation and facilitate reliable response to the emergencies. In orientation meeting, the

Executive Engineer (Emergency Planning Manager) will introduce the revised EAP to local officials



and emergency responders and provide those entities the opportunity to review and comment on the

documents and on their roles, responsibilities described in EAP.

Table-top Exercises: The Superintending Engineer and The Executive Engineer (Emergency

Planning Manager) will organize a table-top drill once in 2 years to discuss and review the simulated

or imaginary emergency situation. The table-top drill involves a meeting of Emergency Planning

Manager with local and state Disaster Management Officials in a conference room. The drill begins

with a description of simulated event and proceeds with discussions by the participants to evaluate

the EAP and response procedures and to resolve concerns regarding coordination and

responsibilities. Any problems identified during a drill should be included in revision to the EAP.

Before the table-top exercise begins, meeting participants will visit the dam to familiarize with the dam

site. Executive Engineer (Emergency Planning Manager) will present a scenario of an unusual or

emergency event at the dam site. The scenario will be developed prior to the exercise with the support

of the Dam Safety Organization.

Once the scenario has been presented, the participants will discuss the risk involved, responses and

related actions that they would take to address and resolve the scenario throughout the exercise. The

exercise provides an opportunity to discuss EAP and response procedures and resolve the questions

throughout the exercise. It will also clarify roles and responsibilities and will identify additional threat

mitigation and preparedness actions.

Records and reporting of the main conclusions / findings of both meetings will be maintained in

ANNEXURE 17 : TRAINING RECORD and following the deadline given in Table 22.
