Field Evaluation of Seepage Measurement Method

Project design, canal lining research and development, and irrigation operation and maintenance require the ability to measure seepage rates, accurately and economically. New methods have not been developed, so existing field methods must be used. Each of the these methods warrants an evaluation of its capabilities and limitations. This paper relates experiences witn ponding tests, seepage meters, and inflow-outflow methods of evaluating seepage from canals
