Sustainable Flood Mitigation Strategies in India
Sustainable flood mitigation solutions and help with riverbank erosion in the Brahmaputra River require a holistic approach involving integrated river management planning and design.
Data and technology are vital to flood mitigation strategies in India. All issues and challenges pertinent to braided behavior, channel migration, horizontal instability, and high sediment load carried by high water discharge are to be addressed through the mathematical hydrodynamic, riverbed and bank erosion, and sediment transport model studies and satellite imagery databased approaches.
Geomorphic assessment, hydrological data, hydraulic data, geotechnical investigation and GPS survey (topography, cross-section etc.,) are to be integrated using Geographical Information System (GIS). The selection of appropriate technology depends on collected site data. In addition, watershed or catchment area management impact in the Brahmaputra is to be integrated in the study.
