Leakage rates through holes in geomembranes overlying geosynthetic clay liners
01 Jan 1995
Abstract
A finite difference method is developed and presented in this paper for predicting the flow rate through a hole in a geomembrane overlying a geosynthetic clay liner. The method is then used to assess the influence of various factors on the leakage rate. The factors considered include the transmissivity at the contact between the geomembrane and the geosynthetic clay liner, the hole size and the hydraulic conductivity and thickness of the bentonite component of the geosynthetic clay liner. The results show that transmissivity has the largest effect. The predicted leakage rates are compared with those expected in composite liners consisting of a geomembrane overlying a compacted clay liner. Realistic properties for both geosynthetic clay liners and compacted clay liners based on published data are used in the computations. The results indicate that expected leakage rates through composite liners using geosynthetic clay liners are generally lower than those through composite liners using compacted clay liners.
