One of the most sensitive parameters in groundwater investigation and modeling is estimation of
groundwater recharge. In this study, parallel to tracer analysis and groundwater modeling, a
geoelectric method was adopted in evaluation of recharge mechanism and aquifer reservoir changes.
The results of geoelectric method were compared and used in tracer analysis and groundwater
modeling. In this research, Geoelectric method was used with two specific objectives in mind. First,
the relation between soil electrical resistivity obtained by dipole method and soil moisture and soil
minerals investigated and showed promising results. Next, the transmisivity of Hashtgerd Aquifer was
estimated by boreholes of Schlumberger method.
To obtain more accurate information from reservoir characteristics, the mechanism and rate of
recharge between boreholes in the past years were investigated and soil moisture and soil minerals
between boundaries were evaluated and verified. The groundwater fluctuations in the region was
analyzed in a more accurate manner comparing to the traditional methods
