Abstract

Nowadays, with the increasing exploitation of groundwater resources, optimal use of these resources is more and more necessary. Geostatistical methods can be used to assess and monitor the quality of groundwater resources. HASHTGERD PLAIN is the case study of this investigation. In this study firstly, by using data from qualitative data which were harvested from 41 Piezometric wells, different qualitative parameters were evaluated, then by using the geostatistical methods such as: Kriging, Co-kriging and IDW the best model for mapping for aquifer quality classification was selected. Results showed that most of the indicators are better simulated by Co-kriging method, based on mutual evaluation and RMSE. The parameters of SAR and EC were selected in order to determine the irrigation water quality parameters according to WILCOX diagram. Based on these two parameters by using ArcGIS v.10 software zoning maps were prepared. Results showed that 99% of the aquifer is classified in the category of good quality irrigation water (C2S1) and 1% level in the aquifer is classified as middle class (C3S1) based on WILCOX diagrams. The results of the study can be used in aquifer management and irrigation management in the agricultural purposes.
