Determination of Water Table Depth using Geophysical Methods

Abstract

Water table (W.T.) depth is an important parameter in engineering and environmental studies. This information can be easily obtained through drilling boreholes. Some geophysical methods can also contribute to indirectly determine the W.T. depth. The methods that are effective in achieving this goal are GPR (ground penetrating radar) and electrical resistivity (ER). Other methods, such as FDEM (frequency domain electromagnetic method), seismic refraction, and seismic reflection, can also be employed to measure W.T. depth. This article presents a discussion on the use of some geophysical methods to determine W.T. depth, based on a brief literature review and analysis of some data obtained by the author.
