Assessing the groundwater potential is an important step in utilization management of groundwater resources. In this study, an attempt has been made to evaluate groundwater potential of Jiroft plain both in terms of quantity and quality. To this purpose, groundwater potential and groundwater quality indexes are identified based on analytic hierarchy process. Geology, groundwater depth, groundwater recharge, rainfall, land use, soil, slope, elevation, drainage density and fault density are used for calculation of groundwater potential index. Also, the groundwater quality index is identified considering total dissolved solids, total hardness, sodium ion, sulphate ion and chloride ion as influencing parameters. Finally, the groundwater potential index and groundwater quality index maps were prepared using geographic information system capabilities. According to results, the Jiroft plain has been classified into three groundwater potential zones namely: good, moderate and poor c. From the groundwater quality viewpoint, the study area has been classified into four quality zones namely: very poor, poor, acceptable and good . According to the results of this study, the most suitable groundwater potential is observed in the middle part of the plain and the least groundwater potential is observed in the eastern and southern margins of the Jiroft plain. In terms of qualitative potential, except for the southern and southwestern parts of the plain, the groundwater quality potential is suitable. The existence of fine-grained sediments in the southern part of the plain is the most important reason for the reduction of quantitative and qualitative groundwater potential.
