Leakage Rates through Composite Liners due to Defects in Geomembranes

A composite liner is composed of’a layer.of geomembra e as upper component and a low-perme­ability soil layer as lower component. This paper present ‘an analytical sol_ution for the evaluation of leakage rate through a composite liner due to defects in geomembranes for general field conditions. A computer program has been provided by the author. Results have been calculated and relevant factors influencing the leakage rate have been analyzed.
