Abstract

In recent years, the electrical imaging method is largely and effectively applied to study the inhomogeneity of electric conductivity in rocky soil environment. It is based on the combination of two vertical electrical sounding(VES) and electrical profiling (EP) methods. The interpretation results give the 2-D conductivity pictures. This paper presents the theoretical fundamentals and the results of application of electrical imaging methods to the Mekong Delta, South-East Vietnam and Ho Chi Minh City.
