Exploration of groundwater potential zones using analytical hierarchical process (AHP) approach in the Godavari river basin of Maharashtra in India

Abstract

Total natural and groundwater resources play the most crucial role in developing ecological, biological and socioeconomic doings. Various parameters like land use, geology, elevation, slope, lineament, lineament density, drainage density and geomorphology affect the groundwater development of recharge and its accessibility. In this research, geographical information system (GIS), remote sensing, weighted overlay analysis and analytical hierarchy process (AHP) methods have been used for groundwater prospects mapping, and identifying suitable solutions site for soil and water conservation structures. To calculate the weights were assigned to every layers component in the determination of affecting factors. The weighted overlay analysis (WOA) tool is applied to give the sub-parameter ratings based on the scientific literature. The final map of potential groundwater zone map has prepared using Arc GIS 10.1 software and AHP methods. About 49.71% of the areas fall under the 'good potential zone, 41.05% falls under the 'moderate potential zone', and 9.22% falls under the 'poor zone by using AHP technique. Groundwater potential zone map is depend on the weighted overlay analysis and analytical hierarchy process (AHP) methods. The highest GWP is located in the lower part of the basin due to the best surface runoff gathering, infiltration situations and subsurface storage volume. The present study procedure, methods and outcomes can be valuable to estimate the suitable groundwater zones parallel to improve the dry land area in the semi-arid and arid regions of India.

Assessment of Groundwater Potential Zone mapping approach for semi-arid environments using GIS-based Analytical Hierarchy Process (AHP) and Multiple Influence Factors (MIF) and multi-criteria decision analysis (MCDA) techniques in Buchakewadi Watershed, Maharashtra, India

“…The value of Consistency Ratio (CR) smaller than or equal to 0.10 (0.022 < 0.10) is acceptable and implies that the matrix is consistent. (Rajesh et al 2021). The Consistency Ratio (CR) of the weights assigned to dissimilar thematic maps of the study area is 0.022, which implies that the matrix is consistent.…”

“…Decision making, for which we have collect most of our material, become a scientific science (Rajesh et al 2021). Psychological studies have found that human beings make biases while making decisions.…”

“…To detect potential groundwater zones in area using AHP. Altogether thematic maps have been assigned suitable weights for potential zones mapping groundwater development (Vidhya et al, 2018;Pande et al 2022;Rajesh et al 2021). The continuous rating scale of Saaty's AHP (Table 3) is used to assign weights to the individual features of each theme for area (Saaty 1980(Saaty , 1986.…”

“…geology, lineament, rainfall, NDVI, slope, land use, and soil types to ensure accuracy and reduce human errors. Historically, suitable groundwater sites were defined using multi-influence factor (MIF), and AHP techniques (Ghimire et al, 2019;Pande et al 2018;Rajesh et al 2021;Pande et al 2021). RS, GIS, and hydrological information were clustered (Selvarani et al 2016), and statistical methods (Murmu et al 2019).…”

Analysis of land suitability for apple-based agroforestry farming in Dire and Legedadi watersheds of Ethiopia: implication for ecosystem services

“…The application of an agroforestry system plays an important role in the conservation of natural resources, especially soil and water conservation ( Pande and Moharir, 2015 ; Rajesh et al., 2021 ). Despite its principal component of soil and water conservation, integrated watershed management is also critical to maintaining biodiversity resources, and enhancing crop production and livestock development (Abhijit et al., 2013).…”
