A PRESENTATION ON

TECHNICAL ISSUES INVOLVED IN WEIR CUM CAUSEWAY ON RIVER NARMADA TO ARREST SALINITY DUE TO BACK (SEA) WATERS and AUGMENTING SURFACE TRANSPORTATION FACILITY BETWEEN BHARUCH & ANKLESHWAR By MK BAROT, Member BCEF Thursday, 17th July, 2003

MOTIVES AND OBJECTIVES OF BCEF

UNLIKE THE “BIG BROTHER” ROLE, BCEF AIMS TO EXTEND A HELPING HAND WITH FUTURISTIC VISION TO LOCAL ADMINISTRATION FOR BETTERMENT OF CIVIC LIFE IN THE REGION.

TAPPING OF TECHNICAL RESOURCES.

TO CREAT ENVIRONMENT CONSCIOUSNESS & QUALITY AWARENESS IN CONSTRUCTION FIELD.

TO SET UP RURAL DEVELOPMENT CELL

CONDUCTING BRAIN STORMING TECHNICAL SESSIONS

MAJOR CAUSE OF CONCERN FOR CITIZENS OF BHARUCH AND ANKLESHWAR

NATURE’S FURY : SALINITY INGRESS – Water-rich region reduced to water-scarce

region.

WATER WOES : ACTUTE DRINKING WATER PROBLEM.

GRINDING HALT : SUDDEN SHUTDOWN OF PLANT. MISSING LINK BETWEEN TWIN CITIES :

STRATEGICALLY IMPORTANT CENTURY OLD GOLDEN BRIDGE HAS OUTLIVED ITS USEFUL LIFE.

SALINITY : BRUNT OF DOUBLE EDGE SWORD FACED BY

THE REGION.

MANAGING FINITE SUPPLY OF NATURE’S BOUNTY :

LIMITED INCOMING WATER AFTER UPCOMING OF DAM AND INCREASED RATE OF SALINITY ON ACCOUNT OF GLOBAL GEOLOGICAL CHANGES.

AS PER THE INFORMATION COLLECTED FROM CENTRAL WATER COMMISSION OFFICE – RATE OF FLOW IN NARMADA RIVER NEAR GADURESHWAR IS AROUND 180 Cu.M/ Sec. I.e. 15552 MLD.

POUND OF FLESH :RIPEARIAN RIGHTS OF THE REGION TO BE REVIEWED.

SWEET WATER REQUIREMENT :

1 ANKLESHWAR GIDC 100 MLD

2 PANOLI GIDC 100 MLD

3 JHAGADIA GIDC 075 MLD

4 ANKLESHWAR CITY 025 MLD

5 BHARUCH CITY 035 MLD

6 GNFC 100 MLD

7 NTPC 075 MLD

8 GPEC 075 MLD

9 VIDEOCONE 075 MLD

10 IPCL 075 MLD

11 BIRLA COPPER 075 MLD

12 GACL 075 MLD

13 INDL. AT DAHEJ 120 MLD

14 TOTAL 1000 MLD

MISSING LINK : EXISTING CONDITION OF SURFACE

TRANSPORTATION BETWEEN TWIN CITIES ? IN HOT WATER ??

120 YEAR OLD GOLDEN BRIDGE : HIGH TIME TO FIND OUT SUBSTITUTE OF HERITAGE

STRUCTURE DUE TODETRIORATED FOUNDATION CONDITION

NEED OF THE DAY : WIDE SPREAD INDUSTRIAL GROWTH RESULTED IN

TO INCREASED TRAFFIC VOLUME CALLS FOR A FULL PROOF LINK.

A PANEL DISCUSSION ON AUGMENTATION IN CONNECTIVITY BETWEEN BHARUCH & ANKLESHWAR STRENGTHENING OF GOLDEN BRIDGE OR NEW BRIDGE ?

Sunday, 30th September, 2001

Organised By BHARUCH CIVIL ENGINEERS FORUM

ABSTRACTS OF CONCLUDING REMARKS

120 YEAR OLD GOLDEN BRIDGE TO BE TREATED AS MONUMENT AND SHOULD BE PRESERVED AS HERITAGE STRUCTURE

TECHNICAL INVESTIGATION TO BE CARRIED OUT FOR ASCERTAINING THE CONDITION OF BRIDGE FOUNDATION

WEIR CUM CAUSEWAY : - TO SOLVE PROBLEM OF POTABLE WATER BY ARRESTING SALINITY DUE TO SEA WATER - TO IMPROVE EXISTING SURFACE TRANSPORTATION FACILITY

RIVER SIDE DEVELOPMENT AS A RECREATIONAL SPOT WHICH WILL HELP IN GENERATING FUND FOR PROJECT

NECESSITY OF WEIR CUM CAUSEWAY ON RIVER

RETIREMENT OF THE CENTURY OLD BRIDGE

CATERING THE NEED OF INCREASED TRAFFIC VOLUME

TO ARREST THE SALINITY INGRESS IN RIVER WATER DUE TO BACK FLOW FROM SEA

CREATION OF SWEET WATER RESERVOIR ESPECIALLY IN VIEW OF THE LIMITED QUANTITY OF INCOMING WATER DUE TO SARDAR SAROVAR PROJECT

INTRODUCTION OF WEIR CUM CAUSEWAY

WEIR : WEIR IS AN IMPERVIOUS BARRIER ACROSS A RIVER TO RAISE THE WATER LEVEL ON ITS UPSTREAM AND TO ARREST BACKWARD FLOW OF WATER FROM DOWN STREAM

CAUSEWAY : A CAUSEWAY IS SMALL SUBMERSIBLE BRIDGE. IT IS ALSO KNOWN AS AN IRISH CAUSEWAY OR DIP

TYPES OF CAUSEWAY : 1 LOW LEVEL CAUSEWAY (LLC) - Without Opening 2 HIGH LEVEL CAUSEWAY (HLC) - With Opening

REQUISITE CONDITIONS FOR WEIR CUM CAUSEWAY

DEPTH OF WATER : SEASONAL FLOW OF WATER SHOULD BE VERY LESS

HIGHEST FLOOD DISCHARGE : FLOW IN THE STREAM SHOULD NOT BE FOR MORE THAN 8 TO 10 DAYS IN A YEAR AND FOR ABOUT 4 TO 5 HOURS DURING THESE DAYS

NORMAL FLOOD DISCHARGE : IT SHOULD NOT BE MORE THAN 40 % OF HIGHEST

FLOOD DISCHARGE

SALIENT & BROWNIE POINTS WEIR CUM CAUSEWAY ACROSS RIVER NARMADA

+ INDUSTRIAL DEVELOPMENT :UNINTRUPETED & SUSTAINED INDUSTRIAL GROWTH.

+ AGRICULTURAL DEVELOPMENT :OPTIMUM UTILIZATION OF LAND FOR IRRIGATION.

+ FISHERIES FRIENDLY PROPOSAL :DISCHARGE OF SWEET WATER ON DOWNSTREAM OF

WEIR SHALL BE SAME AS EARLIER.

+ DEVELOPMENT OF BOATING, RECREATIONAL & NAVIGATIONAL FACILITIES

ADVANTAGES OF WEIR CUM CAUSEWAY - 1

+FOREMOST & BEST WAY OF CONSERVATION OF PRECIOUS NATURAL RESOURCE

+CAN BE USED AS A MEANS OF SURFACE TRANSPORTATION

+ARREST SALINITY DUE TO BACK FLOW FROM SEA WATER

+CREATION OF RESERVOIR FOR PRESERVATION OF SWEET WATER

+PRESERVATION OF UNDERGROUND (SUB SOIL ) SWEET WATER

ADVANTAGES OF WEIR CUM CAUSEWAY - 2

+RISE OF WATER TABLE OF SURROUNDING REGION WHICH WILL, IN TURN, REDUCE THE PUMPING COST

+DEVELOPMENT OF FISHERIES WHICH CAN GENERATE SELF- EMPLOYMENT OPPORTUNITIES

+DEVELOPMENT OF BOATING & RECREATIONAL FACILITIES

+OPTIMIZATION OF RIPARIAN RIGHTS

+CAN BE USED FOR NAVIGATIONAL PURPOSE

SPECIFIC ADVANTAGES OF SELECTING SITE OF CAUSEWAY NEAR GOLDEN BRIDGE

+ ROAD LINK ON BOTH THE ENDS AVAILABLE.

+ MINIMUM RIVER TRAINING WORKS REQUIRED.

+ WILL NOT AFFECT FISHERMAN’S BUSINESS.

+ SERVES DUAL PURPOSE OF SURFACE TRANSPORTATION AS WELL AS ARRESTS SALINITY

+ PICKNIC SPOT CAN BE CREATED ADJOING TO GOLDEN BRIDGE : A HERITAGE MONUMENT.

SHORTCOMING OF WCC AS COMPARED TO BRIDGE

MUCH COSTLIER OPTION (Both Initial Project Cost as well as Maintenance Cost )

RIVER TRAINING WORKS

SILTING PROBLEM IN BASIN

HIGH COST OF DREDGING

HIGH MAINTENANCE COST DUE TO LIKELY DAMAGES DURING FLOODS
