Detection of shallow cavities in Haditha area, western Iraq using ground penetrating radar

Abstract

This research studied the detection of underground cavities using the Ground Penetrating Radar (GPR). This study used a 250 and 500 MHz antenna in three different locations. Where many cavities of different sizes and depths were detected, especially that most of the study area consists of rocky layers (limestone). These cavities reduce support for the ground, which can cause the rocks above them to collapse. The results show that the GPR technique was effective in the region of high resistance. Cavities ranging in size from 1-3 m and 0.8-5 m in depth were det
