Trap Efficiency Estimation of a Large Reservoir

Sediment deposited or trapped in a reservoir can easily be quantified by the simple knowledge of its trap efficiency (T e ). In the present study methods proposed by Brown and Brune have been adopted to estimate T of Pong Reservoir (Beas Dam) on the Beas River in Kangra district of Himachal Pradesh, India. The necessary modifications in the adopted methods have been made using the available data for this reservoir. This modification is basically to take into account the variation in trap efficiency with time
