Investigating Scope of Minimizing Sediment Load and Water Yield through Management of Tributary Catchment
B.P Chaliha Chair since its last tenure has been advocating need of preventing soil erosion in catchment by Ecological Management Practices (EMP) including prevention of soil erosion in gully, torrent and up to 3rd order stream of Brahmaputra Basin for minimizing sediment load on the Brahmaputra River and its tributaries. High sediment load received by the Brahmaputra River System is a major cause of flood and river bank erosion. Implementation of such project need participation of the local people and different government agencies, as the works are of multidisciplinary nature. Need of collaboration between different organizations and states is essential to adopt land and water management practices on watershed basis, so that soil and water conservation can be achieved effectively and water management can be done scientifically for mitigating flood and for better agriculture as well. Use of local material, more particularly local vegetation is extremely important for easy implementation of such projects. Through this project Chair will try to implement preferably vegetative method for controlling surface erosion and river bank erosion in some part of a representative watershed.
To reduce water yield from urban areas of a catchment, Rain Water Harvesting System, both in roof top as well as in community pond etc, can be implemented. The Chair is, therefore, advocating implementation of Rain Water Harvesting System in urban areas of Brahmaputra basin. For practical implementation, a proposal BORUN
ainwater to U
iche) Abhiyan along with a time bound action plan and supporting documents has been submitted to the Government of Assam for implementation in Guwahati city.
The soft copy of the BORUN ABHIYAN and supporting documents are given below:

| ROOF TOP RAIN WATER HARVESTING SYSTEM
| RAIN WATER HARVESTING for URBAN FLOOD PEAK REDUCTION
To have a systematic approach for mitigating flood and erosion problem of Brahmaputra Basin, Chair is advocating both long term and short term measures. In the workshop organized by Water Resources Department, Government of Assam at Assam Water Research And Management Institution (AWRMI), Basistha during 30-31st July, 2016, the Chair provided a well defined 100 days programme for identifying erosion prone reach and vulnerable embankment.
