The electrical leakage detection methods are widely used to locate leaks in the geomembrane liners at landfills. The potential distribution in the medium above the liner determines the leak locations. A reasonable leak current model is the theoretical basis of potential distribution analysis. The traditional leak current model advanced by Parra results in a complex expression of potential, which is...
High voltage direct current electrical method is very effective in landfill leakage detection and location by measuring the potential distribution patterns in the material under the liner. Different effects of two kinds of detecting electrode laying modes, namely, the honeycomb and the grid, on leak location are compared in a little simulative single-liner landfill. Two algorithms are respectively...
