EE020 – Identification of Potential Zone using Remote Sensing

ABSTRACT:

Groundwater is a vital asset contributing fundamentally in all out yearly supply. In any case, overexploitation has exhausted groundwater accessibility impressively and furthermore prompted land subsidence at a few spots. Surveying the potential zone of groundwater energize is critical for the assurance of water quality and the administration of groundwater frameworks. Groundwater potential zones are demarked with the assistance of remote detecting and Geographic Information System (GIS) strategies. In this examination a standard procedure is proposed to decide groundwater potential utilizing combination of RS and GIS strategy.

The composite guide is produced utilizing GIS apparatuses. The exact data to get the parameters that can be considered for distinguishing the groundwater potential zone, for example, topography, incline, seepage thickness, geomorphic units and lineament thickness are produced utilizing the satellite information and overview of India (SOI) toposheets of scale 1:50000. It is then coordinated with weighted overlay in ArcGIS. Appropriate positions are allocated for every classification of these parameters. For the different geomorphic units, weight factors are chosen dependent on their ability to store groundwater.

This system is rehashed for the various layers and resultant layers are renamed. The groundwater potential zones are grouped into five classes like extremely poor, poor, moderate, great and astounding. The utilization of recommended strategy is exhibited for a chosen consider zone in Parbhani locale of Maharashtra. This groundwater potential data will be valuable for powerful recognizable proof of appropriate areas for extraction of water.
