Importance of Desilting Basins in Run-of-River Hydro Projects in Himalayan Region
نویسنده
چکیده
The natural resources of Himalayas in terms of hydro power generation are not only crucial for the Himalayan states of India, but very important for the whole country. These states seem to be keen in exploiting their vast hydro electricity potential for net revenue earning. However, due to weak geological conditions and steep slopes these rivers carry a huge quantity of sediment with them. The suspended part of this sediment causes problems after getting entry through trash racks of power intakes in hydropower projects constructed in Himalayan region. This paper describes the elimination of suspended sediment in run-of-river (ROR) hydro power projects by means of providing desilting basins. Keywords— Desilting chamber, settling efficiency, silt flushing tunnel, suspended sediment concentration, inlet transition, outlet transition.

Design Aspects and Model studies for Silt Flushing Tunnels in Hydro Power Projects
The Himalayan Rivers due to their steep bed and side slopes, narrow width and fragile geology of the region carry huge amount of sediment with them. Many runof-river hydro power projects are coming up on these rivers and suspended sediment enters into the power intake of these projects. Desilting chambers are provided to remove / minimize the suspended sediment from water conductor system. The ...
متن کاملA Review of Desilting Basins Used in Small Hydropower Plants
Small hydropower (SHP) is a renewable, efficient and eco friendly technology. Out of all the essential civil components, the desilting tank is one of the most vital part of SHP schemes, which ejects the sediment and foreign particles carried by water through the conductor system and protects the hydro mechanical equipments. With the passage of time, the desilting device has undergone modificati...
متن کاملNew Approach for Estimation of Natural and Anthropogenic Components in the Recent Tendencies of Erosion Intensity and Suspended Sediment Yield Changes in River Basins
The offered approach is based on the establishment of the functional dependence between river water discharge (Q) and suspended ms ,in a number of observations, which noticeably differs from the mean value (R) of subsequent allocated period(s). The earliest period anthropogenic component during the subsequent period(s) is the difference between an actual suspended sediment yield and its hypothe...

Water requirements of paddy fields in the Gilan Province are provided for by a large irrigation network including Sepidrud reservoir dam, Tarik diversion dam, Fumanat network, Sangar diversion dam, and Sangar right and left canals. Because of the deposition of sediments in the Sepidrud reservoir, its capacity has been reduced profoundly. To overcome this problem, sediments are flushed in the se...
