Groundwater abstraction is increasing day by day due to its increasing demand for various uses. Hosur Union of Krishnagiri district completely depends on groundwater for drinking purpose, since the surface water from Penniyar river is very limited. In the present study the assessment of groundwater quantity of this region is taken up, to ascertain the safe yield. The study reveals that the magnitude of annual rainfall and groundwater potential has a decreasing trend. The discharge rate is more than the recharge rate, leading to depletion of the groundwater level. The critical drawdown and safe yield have also been determined.Keywords

This paper describes the study of groundwater fluctuation in the study area using remote sensing and GIS technique. In this study, Hosur Union of Krishnagiri district, Tamil Nadu, was selected as the study area. The base map of the study area was prepared by using Survey of India Toposheet at a scale of 1:50000. The groundwater fluctuations were studied for varying rainfall intensity. The analysis was carried out using spatial interpolation technique and Thiessen polygon method. For the analysis by spatial interpolation technique, the water level fluctuations for every 4 years interval were considered. In this technique, spline method was used to create the continuous surface for groundwater data. This method considers the distance between both unknown points and known points and measures the spatial correlations between two points so that the weights can change according to the spatial arrangements of samples. In Thiessen polygon method, Voronoi polygons were created so that every location within a polygon is closer to the sample point in that polygon than any other sample point. The Voronoi mapping tool provides a number of methods for assigning or calculating values to polygons. The results by both the methods indicated that the overall groundwater potential is low in the study area.Keywords
