PERCOLATION SPOT LOCATION USING GIS FOR CHECK DAM CONSTRUCTION- TIRUTTANI BLOCK

Abstract

In this wide world, the human kind is abundantly depends upon ground water for living and meeting their day to day needs. Ground water is considered as a vital source in the universe, which contributes inherently in total annual supply. But, there comes the problem of over – exploitation too. This may be provoked due to the carelessness of the people, faulty storage methods etc. Therefore, the storage of water is treated mandatory. One of the ways is about assessing the water pot zones or potential zones for ground water recharge. These zones are utilised for protection and management of ground water systems. The mission of the paper is to identify such zones using Geographic Information System techniques at the particular study area “Tiruttani”. The usage of thematic layers for the study area namely soil texture, soil infiltration, geology, geomorphology, land use land cover, rainfall, drainage
and slope (Mohanavelu Senthilkumar et al., 2019) and the method of Weighted Overlay Analysis in Arc GIS software is examined in detail. The outcome is retrieved in three categories viz. Low, medium and high suitability areas and thence generated the percolation spot location for check dam construction.
