Potential groundwater recharge in north-western India vs spaceborne GRACE gravity anomaly based monsoonal groundwater storage change for evaluation of groundwater potential and sustainability

Using Analytical Hierarchy Process and Multi-Influencing Factors to Map Groundwater Recharge Zones in a Semi-Arid Mediterranean Coastal Aquifer

“…Figure 6 illustrates the GIS analysis procedure to map the spatial distribution of groundwater recharge using the weighted overlay tool of Weighted Overlay analysis tool of ArcGIS 10.1 based on the eight thematic layers and their corresponding percentage influence on recharge [69,70]. Values in the input raster layers were reclassified into a common evaluation scale of 1 (very good), 2 (good), 3 Figure 6 illustrates the GIS analysis procedure to map the spatial distribution of groundwater recharge using the weighted overlay tool of Weighted Overlay analysis tool of ArcGIS 10.1 based on the eight thematic layers and their corresponding percentage influence on recharge [69,70].

“…Quantifying groundwater recharge rate, which is difficult to measure directly [66,70,72,75], improves understanding of watershed scale hydrologic processes. For the Korba case study, groundwater recharge has been estimated to be up to 10% of the 420 mm/year mean average rainfall [7,10].…”

Recognition of district-wise groundwater stress zones using the GLDAS-2 catchment land surface model during lean season in the Indian state of West Bengal

“…Groundwater plays a vital role in agriculture, domestic and industrial sectors for the development of the arid and semi-arid zones because of the unavailability or insufficiently of surface water. Groundwater depletion is one of the major problems in India because of population pressure, rapid urbanization, irregularity in precipitation and intensive use of groundwater for agricultural activity (Chatterjee et al 2020 ). Regional-level groundwater storage depletion mainly depends on temporal responses from natural and artificial effects.…”

“…They used 3907 groundwater monitoring wells for the analysis. Chatterjee et al ( 2020 ) assessed the groundwater potential recharge based on groundwater storage change using the GRACE data for sustainable groundwater management of northeast India. This study indicated the terrain suitability for groundwater recharge based on hydrogeology and terrain parameters with integrated average monsoon recharge.…”

Enhancement of the yield of solar still with the use of solar pond: A review

“…The use of solar energy, due to its low energy level and seasonal characteristics, is related to critical difficulties. The solar pond (SP) can be used to store solar energy in the form of heat and transfer it to other applications 1‐5 …”
