SEDIMENT LOAD OF RIVER TONS

Abstract

So imont deposition is a troublocomo procoso along rivers and Came it raisoo stream bolo, thereby incraos ' ing flood heights, and inundation; it piloo up sediment In immense quantities behind demo, thereby reducing their caps- citioc and function. To evaluate the extent of dcpocition in the reservoirs, the sediment transportation capacity of the, river, should be known. The sediment transportation capacity of river Tons near Dakpothar (Dohradun) has been corputed from different exist-Lag foxmul a and also from the measurement of one Point con- centration 'et 'different diochargec. `ho correct deter n- ation of sediment toad is difficult due to lack of adequate knowledgo about sedimentation rrocoso. However, the coi pu-tation givers fair amount of guess to be used in planning and designs of reservoirs to be built in future on this river.
