The Experiment of Leakpoint Location System for Waste Disposal Lined with Geomembrane

Abstract

Many studies have been made on leakage detection of waste disposal lined with geomembrane. But, there is no method to locate a leak point reliably.
We developed a leak point location system, based on 2 electrical techniques, phase detection and to make anisotropic electric conductivity of ground.
The purposes of this paper are: (i) to describe an outline of the system; (ii) to introduce 2 electrical approaches, phase detection technique and to make anisotropic electric conductivity of ground; (iii) to show some experimental results.
