CANAL SEEPAGE STUDIES BY NUCLEAR TECHNIQUE

Abstract

A brief survey of the many existing computational and experimental methods in estimating seepage losses from unlined canals is given. A method is also described in which the filtration velocity of seepage is measured using radio-isotopes. In this dissertation an attempt has been made to evaluate quantitatively seepage losses from the Ganga Canal and also from Deoband Branch with the help of experimental measurements by single well dilution technique usint radio-active isotopes as tracer. The experiments were carried out on the left bank of Ganga Canal near Solani Aqueduct and the on the left bank of Deoband Branch near Tansipurvillage Inflow-outflow method was also employed to assess directly the seepage losses in order to have comparison of the results.
