SCADA systemsSCADA systems

SCADA stands for Supervisory Control And Data Acquisition. It is a software

application specially designed for monitoring and controlling a process.

SCADA refers to the combination of telemetry and data acquisition and

encompasses the collecting of the information, transferring to a central site,

carrying out any necessary analysis and control, displaying the information

on a number of operator screens or displays and conveyed the required

4

on a number of operator screens or displays and conveyed the required

control actions back to the process.

The term SCADA usually refers to

centralized systems which monitor

and control complexes systems

spread out over large areas

(anything between an industrial

plant and a country).

IntegratedIntegrated WaterWater ResourcesResources ManagementManagement

Integrated Water Resources Management (IWRM) is the process which

promotes the coordinated management and development of water, land

and related resources, in order to maximize the sustainability of

ecosystems.

7

Integrated Water Resource Management is a systematic process for the

sustainable development, allocation and monitoring of water resource use

in the context of social, economic and environmental objectives.

Implementing IWRM process depends on the area, capacity, political

will, and understanding of IWRM concepts and their implementation.

The needed of a holistic approach to water resources,

taken into account the water resources exploitation, the

water environment protection, the prevention and

mitigation of damages, the public awareness, etc, makes

mitigation of damages, the public awareness, etc, makes

the SCADA based networks a powerful tool for the River

Basin Organizations, or for others decision makers, to

develop an integrated policy for water management.


• Rivers flow control and floods prevention

• Drought management

• Wells and aquifers monitoring and control

• Water quality control

Application of SCADA systems in IWRMApplication of SCADA systems in IWRM

• Water quality control

• Management and Operation of Hydraulic Infrastructures:

- Dams

- Pumping Stations

- Wells

- Irrigation Fields

- Water treatment plants

- Others


Some of the collected data are:

• Reservoirs & Wells:Water Level and Quality parameters

• Pumping Stations:Water flow Pumping and electrical parameters

• Dams, lakes and waterwheels: Water levels

11

Water levels Water flow in canals, pipes, tubes etc.. Positions of floodgates and valves

• Rivers: Water flow stations and Quality parameters

• Meteorological Stations:TemperatureHumiditySolar RadiationWind speed and direction Evaporation


HOW DOES THE SCADA BASED NETWORK WORK?

In every hydrological basin data are collected by means of different sensor devices and transmitted to a communication network.

Water Level (Dams, Wells, Reservoirs)Submerged Quartz Transducer ,

12

Submerged Quartz Transducer , Float-Counterweight

Water Flow (Channel, Pipeline)Electromagnetic FlowmeterUltrsonic Flowmeter

Valves Position

Rain Gauges

Etc.


Data are transmitted to a Control Centre where they are processed by aSCADA, and presented to the user, who can evaluate with a better knowledgethe conditions of each basin.

Water resources exploitation in normal circumstances is optimized,facilitating the saving and reducing losses.

Forecasting hydrological models are also widely used to facilitate thedevelopment of water policies for IWRM.

With a population of 45 M people, Spain has a hydrological renewable resourcesof about 111.000 M of m3, close to the 2.500 m3 / inhabitant and year.

However its distribution is very irregular both in space and in time, due to thisirregularity, associated effects from drought and floods have risen.

The control of these effects has promoted the development of hydrologicalinfrastructure where there objective is to help the decision makers to optimisethe exploitation of the resource and to guaranty the security in cases of floods.

the exploitation of the resource and to guaranty the security in cases of floods.

Spanish water resources are divided into 10 main hydrological areas, managedby some organisms called Confederaciones Hidrográficas.

In order to make possible an integral water resources management, theformer General Directorate for Hydraulic Works created in 1982 a programfor the establishment of an Automatic Hydrological Information System(SAIH).
