Abstract :
Water resources management, especially groundwater, is particularly important in arid and semi-arid regions. Various natural and anthropogenic factors, especially in recent decades, have caused critical conditions and groundwater levels in most parts of the country, including Kurdistan province. Therefore, the study of groundwater level drop in Qorveh plain, which is one of the most essential and most extensive plains in the area, is of great interest. It placed. To carry out this study, the statistics of 28 observation wells over two 5-year periods (88-88 and 88-92) studied. Initially, statistical data were collected, and after data entry into Geographic Information System (GIS), interpolation methods, maps of co-potential lines, and groundwater loss zoning prepared. Water level hydrographs also plotted in the Excel software environment. The results obtained from the overlap maps showed that the highest groundwater level in the second 5 years in the western part of the aquifer was 5.75 meters and in the first five years in the eastern parts was 2.15 meters. Groundwater level hydrographs show that during the ten years, the water level in the Qorveh plain was 10.84 meters, which averaged 1.08 meters per year.
