Abstract

The main objective of this research is to monitor groundwater levels using remote sensing and satellite images and its relationship with land use. For this purpose, first the relevant images were obtained and the necessary pre-processing was applied to each of them. Then, the images were modeled and classified. In order to examine land use changes, a classified land use map was extracted for both 2002 and 2023 using the object-oriented classification method, and then, in order to examine land use changes, a land use change map was extracted for a 20-year period. After extracting the land use change map, all models were evaluated to select the best interpolation model among different models, RBF, IDW, and Kriging. Among the changed land uses, residential use, that is, urban and rural areas, has increased. In almost all land uses, residential areas have been a significant figure in their own right, which indicates urban development as well as human interference and destruction of natural resources. The results of the groundwater survey showed that the highest average water level in 2003 was recorded for the water area with 53.12 meters and the residential area with 48.17 meters, and the lowest average water level was recorded for the agricultural land area with 45.48 meters. In 2023, the highest average water level belonged to the water area with 36.89 meters of gardens with a value of 32.78, and the lowest average water level recorded belonged to the residential area with 24.16 meters.
