BHARUCHCIVILENGINEERS FORUM Organises 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.
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 TO DETRIORATED 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.
