“…Sloped areas do not have adequate dwell time for water to penetrate and replenish the aquifer (De Reu et al, 2013). As a result, locations with a steep slope received less weight, and places with a flat slope received more weight (Andualem and Demeke, 2019;Hussein et al, 2017;Ibrahim-Bathis and Ahmed, 2016;Saravanan et al, 2020).…”

“…Furthermore, drainage density is negatively related to soil infiltration ability. Areas with poor drainage density were given a high weight, and vice versa (Andualem and Demeke, 2019;Harlin and Wijeyawickrema, 1985;Ibrahim-Bathis and Ahmed, 2016;Patra et al, 2018;Rahmati et al, 2015;Saravanan et al, 2020). The drainage line was created using the DEM and the flow accumulation, and the drainage density map for the research region was created using ArcGIS.…”

“…The weight of selected groundwater contributing factors (geology, slope, drainage density, LULC, rainfall, available water capacity, fault density, soil texture, saturated hydraulic conductivity, and soil depth) was assigned to delineate the groundwater prospective zones (Magesh et al, 2012;Arshad et al, 2020) of the Cuma sub-basin. The selected factors weight was assigned based on their influence on the movement and occurrence of groundwater collected from expert knowledge and suggestions from works of literature (Andualem and Demeke, 2019;Yeh et al, 2016;Saravanan et al, 2020;Rahmati et al, 2015;Nampak et al, 2014;Patra et al, 2018;Pande et al, 2018;Magesh et al, 2012;Ibrahim-Bathis and Ahmed, 2016;Kumar et al, 2016;Arulbalaji et al, 2019).…”

Groundwater is an essential component of our country's freshwater supplies. It plays a critical role in satisfying the water demands of the nation's many user sectors. The groundwater resource cannot be exploited and sustained optimally unless prospective zones are identified prior to the drilling of wells. The current study intended to analyze groundwater potential possibilities in the Cuma sub-basin, Omo Gibe basin, southern Ethiopia, utilizing geospatial and multi-criteria decision analysis approaches. For this purpose, a range of thematic layers like geology, Rainfall, drainage density, slope, land use and land cover (LULC), Soil type, faults density, saturated hydraulic conductivity, Available water capacity, and soil depth were organized for the study area. The different sub-criteria of each theme layer were rated according to their effect on groundwater recharge, and a weightage was assigned to each thematic layer based on the analytical hierarchy method (AHP). The identification of groundwater-potential regions of the sub-basin was one of the study's main results. The resulting groundwater potential zone map is further classified into five groundwater potential classes: very good (7.01%), good (19.49%), moderate (17.48%), poor (29.51%), and very poor (26.51%). The study's findings have important significance for developing sustainable groundwater strategies in the area.

“…have been employed around the world (Chaudhuri & Ale 2014;Saha et al 2019;Ijumulana et al 2020;Quino Lima et al 2021). Among them GIS and remote sensing techniques are increasingly being used to locate, delineate, and portray groundwater potential zones (see for example, (Srinivasa Rao & Jugran 2003;Magesh et al 2012;Ghorbani Nejad et al 2017;Al-Djazouli et al 2020;Saravanan et al 2020)) for fast and effective estimation of natural resources and geospatial data in a cost effective manner prior to opt for any meticulous and expensive surveying methods (Lambrechts & Sinha 2016). This study delineated groundwater potential zones integrating Analytical Hierarchy Process (AHP) and geospatial techniques together.…”

The objective of this research is to identify groundwater potential zones for Bangladesh. Fourteen influential factors associated with topography, geology and metrological concerns were applied for this study. Weights for factors and sub-factors within a factor were calculated based on pairwise comparisons. The groundwater potential zones were delineated through GIS-based weighted overlays of factor maps. According to the pairwise comparison, the consistency ratios for factors and sub-factors were within the allowable range (i.e., less than 0.10). General soil type (eigenvalue 0.17), geology (eigenvalue 0.16), and geomorphology (eigenvalue 0.15) were the most important factors in determining groundwater potential zoning. The groundwater potential index has maximum and minimum values of 45.99 and 10.34, respectively. According to the groundwater potential map, relatively higher groundwater potential zones were found in the southern parts of Bangladesh and along major rivers. The study's findings will be useful to government authorities in making evidence-based decisions about national water policy and planning.

regions across the world. [1][2][3][4] Groundwater is an important resource contributing significantly to total annual supply. [5,6] Uncontaminated and groundwater is a crucial to sustain life on earth, particularly at the present time when water scarcity is becoming central issue in many nations across the globe. [7] The tropical and subtropical regions are severely affected with the problems related to groundwater. [8] The groundwater resources potential of Ethiopia is estimated to be about 40 billion cubic meters. [9] According to ref, [10] groundwater provides more than 90% of the water for domestic and industrial supply in Ethiopia, but a very small percentage of water is used for irrigation, which mostly generate from surface water. However, Ethiopia has also suffered frequent devastating droughts with severe ramifications comprising famine, augmented poverty, and civil unrest. [10] Overexploitation has exhausted groundwater availability noticeably and also led to land subsidence at some places. [11] To control land degradation, long-term sustainable utilization of water resources, new methods for the controlling of land and water resources are increasing in the present day. Hence, assessing and constructing groundwater potential mapping is very much indispensable for better improvement of groundwater resources and techniques for its investigation. [12][13][14][15][16][17][18][19][20][21][22] In the Abay basin, groundwater is a source of domestic water in urban and rural areas. [23] According to ref [23] inadequate public water supply is being a serious problem for the community in Muga watershed due to population growth. The practical development of the groundwater resources will have a significant effect on the improvement of the community's livelihood. Generating a groundwater potential map has a significant effect to enhance the sustainable management of groundwater resources in the study area. Thus, the present study is critical for quick identification of groundwater potential for better utility in the study watershed.Geographic Information System (GIS) is a computer based system that can be used capture, store, manipulate, analyze and present geospatial data to solve several complex and complicated problem in the environment. [24] Recently, the application of GIS is being powerful and applied to deciphering the potential areas of groundwater occurrence with cost effective Groundwater is an important resource that contributes significantly to the total annual water supply. The purpose of the present study is to assess and delineate the groundwater recharge zone using geospatial technology through an analytical hierarchal process (AHP) method in to the Muga watershed, Abay Basin. Remote sensing satellite images and the corresponding data are used for the preparation of thematic layers, viz., geology, rainfall, slope, soil, curvature, topography wetness index, elevation, drainage density, land use land cover, and lineament density of the study watershed. All thematic layers are integrated with a multicr...
