Flood Control & River Morphology
Floods create havoc and cause a lot of damage to life and property from year to year. River management aspects have acquired new dimensions due to increasing urbanisation along the rivers, encroachment of flood plains and human interference by developmental activities. The focus is on treating the river basin as a whole covering geomorphological aspects, damage frequency analysis, risk assessment, evaluation, risk coverage through insurance etc. with emphasis on flood forecasting and disaster management.
Rivers frequently damage land and property adjacent to their banks. Rivers in alluvial plains also frequently alter their courses. It is essential to stabilize the river channels along alignments to provide safe passage to floods, prevent outflanking of bridges, embankments, etc.
Due to influx of population in urban areas and resulting pressures on the land resources, the lands along the river courses have to be jacketed to be reclaimed and utilized. Flood protection works have to be provided to ensure safety of such habitations. WAPCOS has been providing expert consultancy services in mitigation of floods.
