dc.description.abstractRivers carry a huge amount of sediment load with water. Several river valley projects have been constructed on these rivers, whose live storage capacity depends on the sediment load transported by these rivers. Sediment deposition in the reservoir pool gradually reduces the storage capacity of reservoir. As a result, after certain stage, the reservoir is unable to provide useful service. The coarser portion of the inflowing sediment load is deposited where river enter reservoirs, forming delta deposits, which can cause channel aggradations. Channel aggradations can increase flooding of infrastructure, increase groundwater levels, create water logging and soil salinization. In hydropower facilities, sediment coarser than 0.1 mm greatly accelerates the erosion of turbine runners and pelton wheel nozzles resulting damage of hydropower projects. Keeping in view the losses due to sedimentation. it is essential that the gradual reduction in the storage capacity due to deposition of the sediment brought by the rivers should kept in mid at the time of planning of reservoirs. The engineering techniques as well as GIS and remote sensing techniques should be used for the reliable management of reservoir sedimentation to reduce the losses. In the present paper, effects on reservoir due to sedimentation, its management and sediment rates in Indian reservoirs have been discussed. In addition, a comparison with actual and design rate of sedimentation, and effect on storage capacity due to reservoir sedimentation in Indian reservoirs have also been made.en_US
