The aim of these studies is undersurface exploration of the depth of 3 to 15 m. The region under study was marked and profiled and all measurements were performed on determined profiles. After processing and expounding of removed sections according to obtained radar grams, some abnormalities were observed that mainly showed some undersurface looseness or small local cavities</span></span></p>
