Karst cavities detection investigations: a case study in Kuwait

A thorough investigation program for the detection and delineation of karst cavities was undertaken in Al-Dhahar area, Kuwait. The investigation program included, topographical and aerial, geophysical and geotechnical and geological investigations. The investigations result indicated that the karst cavities encountered had the form of thin interconnected tunnels network. There was, in general, a good correlation between the topographical, geophysical, geological and geotechnical investigations in terms of delineating the locations and nature of karst cavities. However, the geophysical investigation presented few cases of mismatching with the other investigations. The inconsistency might be attributed to either the thin, interconnected tunnels network nature of the karst cavities or due to the incorrect presentation of the gravity contour maps,
