Abstract

Groundwater Vulnerability assessment is important in order to prioritize these resources from the perspective of exploitation, management and control of pollution in different areas. The purpose of this study was to evaluate the qualitative Vulnerability of Birjand Plain aquifer using DRASTIC-LU model. In this research, the DRASTIC base model with the land use parameter of the developed lands was used. In this method, the basic model parameters including Groundwater depth, net nutrition, aquifer environment, soil type, topography, unsaturated area constituents, and hydraulic guidance were analyzed in GIS environment along with land use variable as a model development based on standard weights and the Vulnerability zoning map was prepared. Vulnerability zoning map of DRASTIC-LU model showed that 62. 27, 25. 07, 17. 17, and 2. 38% of the area have low to medium, medium to high, low and high Vulnerability, respectively. In addition, the Sensitivity Analysis of the model used to evaluate the assigned weights was performed. To validate the model, the correlation of the model with the nitrate concentration was performed; the obtained correlation of 86% indicated the appropriate correlation of this model with the nitrate concentration as an indicator of Groundwater pollution.
