Identification of Groundwater Potential Area Using Remote Sensing and GIS Technıque: An Example for Eskisehir/Inönü Plain

2022    Yılmaz, İsmail; Yasin, Didem

With the global warming, the protection and exploration of groundwater resources has increased in importance for both rural and urban areas. Geographic Information Systems (GIS) and Remote Sensing technologies are also actively used in groundwater exploration. The aim of this study is to determine the Groundwater Potential Area of Eskişehir İnönü Plain using Remote Sensing and GIS Techniques. Slope, precipitation, lithology, lineament, drainage density and land cover data were used to evaluate the groundwater potential. SRTM data was used for slope and drainage density, LANDSAT-TM satellite image was used to obtain lineament data, and CORINE data was used for land cover. In addition, station data of the Turkish State Meteorological Service were used for precipitation data, and 1/100 000 geological maps of the General Directorate of Mineral Exploration and Research (MTA) were used for lithology. In order to evaluate the effect of the determined factors on the groundwater potential, a literature search was conducted, and relative weight percentages were assigned to each factor. Using the Weighted Overlay tool on the numerically created layers in ArcGIS software, they were overlapped according to the weight percentages determined and the result map was obtained. The resulting map is divided into 5 classes: very low zone, low zone, moderate zone, good zone, and fairly good zone. According to the obtained results, it was determined that the groundwater potential may be high in the NE and SE parts of the İnönü plain.
