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

This study's primary objective is to detect shallow cavities in   Haditha area using ground penetrating radar (GPR) at three selected sites.

Many shallow cavities have been detected using ground penetrating radar, which is a fast, effective, highly accurate and non-destructive technology. In this study, 250 and 500 MHz antennas were used in three separate locations. The obtained GPR data were processed using Reflex WTM, which is a standalone software package that can accept several types of data. After processing the GPR data, a large number of cavities of different sizes and depths were discovered, because the largest part of the research area consists of rock layers (limestone) with distinct reflectivity. At the first site, more than one cavity was discovered, the first with a depth of 1.5 meters and a height of 1 meter, and a second cavity with a depth of 2 meters and a width of 2 meters. At the second site a 3-meter-high  was discovered and additional anomalies are believed to be cavities at the second site with a depth of between 1 and 2.5 metres. In the third site, cavities were discovered with depths ranging between (1-3 m). These cavities threaten the stability of the earth and may cause the rocks above it to fall.
