Discovering ground water resources as one way of supplying drinking water of the world is an essential and inevitable issue due to the increasing demand for water. In this research، we tried to use the available raw data، such as geological layers، topographic maps، maps of water wells in the region and channel maps and faults in the region to produce maps such as slope، floor height، drainage density of Category 2 and 3 and the distance from waterways of Category 3 and distance from the fault. Each layer was given a weight from 1 to 9 and they were prioritized based on their potential finding percent; then، to have an accurate map of the potential of the existing layer set، they were integrated based on mathematical method and the zones of high power have been identified.The results show that 104 km2 of plain areas of Arsanjan have high capability to extract drinking water. The more areas are in the north، North East and central plain and small parts are in the southwest part and in accordance with the low altitude and slope down، the highest channel density and the lowest distance from the waterways is for the waterways and faults. Due to falling water table of Arsanjan plain، there is a need for more measures such as monitoring the exploitation of water resources، basin water transfer between artificial recharge plain areas with high potential.

oohay@353111 hsuirad:liam-E Groundwater Resource Potential Mapping Using the Weighted Index Overlay Method (A Case Study of Arasanjan Plain) Abstract {IBThe discovery of groundwater resources as one of the ways to supply drinking water in the world, given the increasing global need for water, is an essential and unavoidable matter.
(2003) using remote sensing data and various layers such as precipitation, geology, topography, and lithology, have investigated the recovery potential of groundwater resources in India, reaching acceptable results.
Gauss (2003) and Khan (2002) produced maps of groundwater resource potential in the river basins of India by combining remote sensing data and Geographic Information Systems.
(Refer to the page image) Materials and Methods: Groundwater resource potential assessment is carried out through various methods, such as surface geophysics, geoelectrics, and exploratory drilling, based on lithological, hydrological, climatic, and topographic analyses (Sedaghat, 1387).
(Refer to the page image) -Drainage density layer Numerous studies have been conducted regarding the role of drainage stream orders on groundwater resources, and orders 3 and above are considered suitable for water resource potential assessment (Sarraf et al.
(Refer to the page image) Conclusion: Considering the obtained results and the water yield status of the plain, especially in terms of the quantity and quality of water resources in the plain area, high potential areas in map number (8) have less risk for well drilling and also have suitable conditions for artificial recharge of groundwater.
