Assessment of recharge potential zones for groundwater development and management using geospatial and MCDA technologies in semiarid region of Western India

Abstract

Groundwater recharge potential (GWRP) plays a vital role as it directly or indirectly supports domestic, agriculture and industrial activities by infiltrating the rainwater. The present paper touches upon the methodology delineating groundwater recharge potential zones by applying geospatial and multi-criteria decision analysis (MCDA) to the derived thematic layers based on significant influence of occurrence of groundwater in semiarid watershed of Western India. The satellite imageries and other ancillary data were utilized to generate various thematic layers, viz. slope, geology, drainage density, surface run off, geomorphology, land use/land cover soil and vadose zone. The outcome of study shows that about 24.69% is having high GWRP and 24.17% of the area is moderate for recharge of groundwater, while the low and poor groundwater recharges potential area is about 44.34% and 6.80% of total area, respectively. The validation of the study was done by overlaying point data groundwater well yield on the output final map; it shows good correlation with result. Also, the surplus water availability was calculated based on vadose calculation according to CGWB method; it shows 17.12 MCM vadose region having artificial recharge of 22.77 MCM. The total recharge is about 117.41 MCM, about 30% of the total runoff, i.e. 35.22 MCM is considered as surplus monsoon runoff available for artificial recharge. The result shows that the use of remote sensing, geospatial and MCDA technologies are promising and efficiently recognize the suitable regions for groundwater recharge over other conventional techniques.

Approaches for Delineating Groundwater Recharge Potential Zone Using Fuzzy Logic Model

“…The basic land use class categories are crop land, barren land, forest, built-up area, and water bodies (Figure 8). Forest and agriculture land create modest overland flow [38], making it "very high" for groundwater recharge and assigned a fuzzified value of 0.51-1. Built-up region, on the other hand, percolates less water and hence has a membership value of 0.072 as a site with very low groundwater recharge potential (Table 6).…”

“…Surface water resources are generally insufficient to meet the needs of the community, and groundwater is a critical means of attaining freshwater for more than half the world's population [3][4][5]. Surface water includes any freshwater that is channelled into wetlands, stream systems, and lakes, while groundwater is found in subterranean aquifers [6]. Most groundwater is obtained from snowmelt and rainfall that enters the bedrock via the surrounding soil.…”

Comparative assessment of groundwater recharge estimation using physical-based models and empirical methods in Upper Greater Mae Klong Irrigation Project, Thailand

“…For example, the assessment of groundwater potential in the Thachin and Mae Klong River Basins was studied in 2008; the recharge rates were estimated and classified according to the specific crops and land use types in the area (Department of Groundwater Resources, 2008). In addition, the potential sites of groundwater recharge in arid and semiarid regions in Asia have been assessed in numerous studies by applying geospatial and multi-criteria decision analysis technologies (Kadam et al, 2020;Kaewdum and Chotpantarat, 2021;Xu et al, 2021). The potential of utilizing groundwater resources in transboundary aquifers has received much attention for the sustainable development of groundwater systems (Liu et al, 2020;United Nations Educational Scientific and Cultural Organization, 2006).…”
