Ground Water Potential Zone Mapping Using Remote Sensing and GIS in Saurashtra Region of Gujarat, India

Abstract

AbstractGround water is the water contained in the soil pores under the earth’s crust. The challenges of ground water shortages and contamination have become worse in recent decades as a result of population development. Traditional approaches for groundwater conservation, such as groundwater based surveys, exploratory exploration, and geophysical techniques, are not only inefficient yet often time consuming. As a result, an advanced Remote Sensing and Geographic Information System (GIS) approach is used. Ground water management may be divided into distinct Potential Zones based on the amount of ground water accessible in a given region. Using Remote Sensing and GIS, any area’s ground water potential zone can be calculated by combining tiff maps and assigning ranks and weightages to each parameter. Slope, drainage density, geomorphology, Lineament Density, Soil, Lithology, and LULC (Land Use Land Cover) are the parameters used to determine the possible zone of ground water in any given region. This paper describes the work that went into determining the GW potential zone in Gujarat’s Saurashtra region. The area from which ground water can be readily accessed can be determined using the Ground Water Potential Zone chart, and this information can be used to dig wells and create hydrological structures.KeywordsGround waterPotential zone mappingGISWater levelLULC
