Abstract: (23 Views) |
In recent years, due to the lack of water as a result of human activities such as agriculture, industry and domestic use, the extraction of underground water has increased greatly. This has doubled the need to identify potential groundwater areas for artificial recharge. 9 effective factors including lithology, slope, land use/land cover, soil, drainage density, geological line density, landform, altitude and annual rainfall were identified as effective factors in groundwater feeding and were analyzed in GIS of environment. Based on the obtained results, the region was classified into five classes (GPRZ) of groundwater potential feeding potential, including very high, high, medium, low and very low feeding potential.
The results show that about 1.874 square kilometers (24.8%) of the class with very high nutritional potential, 1558.2 square kilometers (44.4%) in the class with high potential, 773.7 square kilometers (22.1%) is in the class with medium potential, 2.59 square kilometers (1.7%) is in the class with low potential and 1.244 square kilometers (7%) is in the class with very low potential. |
