Abstract

Water is an essential need for plant development. Subsurface water or groundwater is an essential source of water for farmers. Due to extensive overexploitation of the groundwater in agriculture, industrial and domestic purpose has resulted the depletion of quantity and quality of groundwater worldwide. Consequently, it is essential to replenish the groundwater and avoid its deterioration for sustainable agriculture development. Therefore, planning and management is critically needed in order to efficient utilization of groundwater resources. In hydrology and the development of water resources, the use of remote sensing and GIS is rapidly and significantly growing. Nowadays, with ease of availability of geographic, spectral, and temporal data over vast and inaccessible locations in a short period of time, remote sensing has become a very effective method for assessing, monitoring, and maintaining groundwater resources. The straight forward interpretation of satellite data provides immediate and useful baseline data on the variables that influence the occurrence and flow of groundwater, such as lithology/structural geology, geomorphology, soils, land use and land cover, slope, lineament, and geology. Groundwater is a critical and valuable resource for development. Consequently, groundwater evaluation and management are crucial. To fulfil the demand for freshwater, it has become essential to locate new groundwater potential zones at a low cost and to develop effective groundwater management and recharge strategies. Numerous assessments of ground water potential zones have been undertaken; thus, this study provides a concise summary of their results.

Conclusion

Understanding groundwater resources is essential for the recharge and management of groundwater. This document provides an updated summary of groundwater potential approaches based on a comprehensive literature assessment. Various researchers' findings indicate that the identification of groundwater potential zones necessitates the construction of distinct thematic layers. Obtaining acceptable potential zones using Remote Sensing and GIS requires a thorough evaluation of the weightage. Among all strategies for overlay, the Analytical Hierarchy Process (AHP) methodology provides the highest degree of precision.
