RESISTIVITY MEASUREMENTS FOR WATER LEAKAGE OF ABANDONED SMALL EMBANKMENT DAM

In this study, the water content of the base sediments and rocks under an abandoned small waste water dam in Selcuk University campus in Konya was monitored. This small dam was planned to construct for the beneficiation of the waste water of Selcuk University main campus. After usage of a few mouths, the dam was demolished by campus authorities due to its water leakage through its base sediments. The study presented here contains the work done to determine water localization in the base rocks in front of the dam. The field measurements here were performed by using electrical resistivity measuring equipment. In order to control the water content of the baserock, Wenner-Alfa electrode lining method were used to collect earth resistivity values. Collected data penetrates as deep as 50 meters in ground. This paper presents the resistivity graphs obtained from the field tests. They clearly demonstrated the water passageway in the sediments located. Water traveled through dry river sediments and it was determined that water flows 25 meters underground towards the lowland even in summer times.
