Abstract
Determination of the geometry and the dimensions of a cave is an important factor considered for planning geotechnical, archeological, speleological studies, and quarrying activities. In recent years, researchers have raised an increasing number of questions related to the shape and size of cavities using 2D geoelectrical resistivity imaging techniques. The inverse model is valuable in detecting the location and extent of subterranean cavities. In this study, a 2D geoelectrical resistivity imaging technique is employed to determine the geometry of a known subterranean cavity. The results provided valuable information and demonstrated the effectiveness of the technique for exploring the size of cavities. Abstract Copyright (2009) Elsevier, B.V.
