“…Ghosh et al studied the upper Kangsabati river basin; the result of the overall accuracy assessment was 79.77%, which supports the validity of the study. The authors also claimed that slope was most dominant factor among the seven selected hydro-geological factors that influence the occurrence of groundwater [64]. Zhu and Abdelkareem (2021) determined that the groundwater potential zones of East Indian regions contain nearly 40% land with very high potential.…”

The Harran Basin is an important region where agricultural activities have been conducted for millennia. The agricultural water needs of the basin are largely met with surface irrigation through the GAP (South-Eastern Anatolian Project), while groundwater is used in some regions as potable water, tap water, and irrigation water. In this study, the groundwater potential of the Harran Basin was determined through the “GIS-based Multi-Criteria Decision Making (MCDM)” Method. Ten criteria were considered: Land Use, Soil, Geomorphology, Geology, Aquifer, Drainage Density, Rainfall, Slope, Lineament Density, and Terrain Class. The weights of these criteria were determined through the AHP method, and the operations were performed in the ArcGIS environment. As the results of this study, the Groundwater Potential Index (GWPI) values were obtained, and five regions were determined based on their Groundwater Potential Zone (GWPZ) classifications: very poor GWPI: 0.10% (5.14 km2); poor GWPI: 29.20%; moderate GWPI: 38.20%; good GWPI: 30.90%; and very good GWPI: 1.50%). We determined that the region is a plain with a low slope and geologically consists of limestone. Notably, areas with poor water potential are mountainous and hilly, and the slopes over these areas are high.

“…The steepness of the land slope can directly control the rate that in incident rainfall can infiltrate through the soil profile and recharge groundwater. A steeper slope results in more surface runoff and lower groundwater recharge due to insufficient time to percolate into the soil profile, and so there is always an inverse connection between surface water infiltration and slope (Ghosh et al 2020;Rajasekhar et al 2019;Murmu et al 2019;Roy et al 2021). On the other hand, almost flat and gentle slope gradients have a good prospect for groundwater recharge as there is sufficient time to allow surface water to infiltrate into a soil profile and reach the water table.…”

Ground water is a precious natural resource in every aspect of human life from natural to artificial environment. Ground water is an indicator of regional development by improving the economic domain through intensive agricultural practices, and aesthetic value through sufficient ground water supply as drinking water, fertile soil, and healthy vegetation. However, ground water availability and associated human perceptions were the main themes of the present study. In this study, both primary and secondary data were incorporated to understand the human adaptation behaviour in drought-prone areas of the fringe of Chhotanagpur plateau region (Bankura-I and II blocks) to ground water storage. GWPZ mapping is a very important exposure to knowing the ground reality. So, the MCDM-AHP method has been developed based on the eight dominant conditioning factors viz. geomorphology, lithology, lineament density, soil, drainage density, LULC, average slope, and slope aspect using GIS analytics with field expertise. The output result was validated with comparing 105 inventory stations where 0.850 AUC value was good for accepting the GWPZ model. As a result, a major portion of the study area is dominated by poor to moderate possibilities of ground water level (ground water level drops 1–2 m during the pre-monsoon) due to Proterozoic granite gneiss formation over the study area. With comparing demographic status, it was not favourable for a healthy lifestyle. Agriculture dominated rural environment of Bankura-I and II blocks is far away from the modern digital environment that is why ground water has played a very crucial role in the field of development. Moreover, to build up a good level of ground water recharge zone through rainfall harvesting, and sustainable land use planning will be the best management practices. So, availability of ground water should be a positive sign of development in the field of the economic sector and sustainable human society.

The water demand in Egypt has risen due to limited surface water and varied uses. Geological and hydrological data, radar, optical remote sensing data, and Geographic Information System techniques delineate groundwater availability zones in the study area. Thematic layers (lithology, topography, slope, stream networks, lineaments, and rainfall) were integrated into the ArcGIS 10.4 using a linear weighted combination technique. The final groundwater prospective zones (GWPZ) map revealed six zones, very low, low, moderate, high, very high, and excellent, covering areas of 7.49%, 14.93%, 3.74%, 28.88%, 37.30%, and 7.62%, respectively. The GWPZ map was tested and compared to the abstraction rates, locations of existing wells, and thickness of the water-bearing formations. NDVI analysis revealed an increase in the area's vegetation from 1984 to 2017. Geochemical analyses of 43 groundwater samples revealed water-rock interactions, ion exchange, evaporation, and the influence of irrigation-return flows as prominent processes influencing ion enrichment of the groundwater.
