Abstract

The electrical resistivity method has been accomplished for the detection of subsurface karst hazards using Dipole – dipole and Wenner – Schlumberger arrays with an a-spacing equal to 1m and n-factor 6 at three selected stations. The results indicate the area formed a weakness zone as two separated zones, the first at an approximate depth (2.5-5) m within the quaternary deposits and the second weakness zone within Injana Formation deposits at an approximate depth (7 – >12) m. The investigation advises conducting physical, chemical and engineering site investigations to decide the suitable treatment techniques to solve these problems.
