The Relation Between the Variation of Electrical Resistivity Values and Moisture of Soil at Baghdad University, Iraq

Six ERI profiles using Wenner Schlumberger array were carried out at Baghdad University (ALJadiriya campus) to investigate soil two sites. The spacing between electrodes of four surrounding the new building in Campus first site is 1 m, and profile length ranges from 50 90 m. In comparison, across garden detect water seepage site. inverted model studied shows many high low resistivity zone. sedimentology mineralogy samples analysis a depth range 15 100 cm three pits confirm homogeneity composed (silt clay). values coincided with moisture amount vegetable herbs growth. Therefore, authors believe main factor causing variation value study area Factor.
