Abstract
The graphical representations of groundwater models play productive role in hydrological impacts like groundwater movement especially in rural areas. The demand of water for agriculture, domestic, industrial and other uses are increasing due to rise in population, over-withdrawal of groundwater and global warming (?). Periodic evaluation of groundwater levels are very much necessary for effective management due to rapidly changing climatic scenario. Geospatial technique have become the most significant tool for mapping and modeling of groundwater level resources using statistical data. An effort has been made to describe the groundwater level of Piriyapatna taluk of Karnataka State. Eight representative observation well points of pre-monsoon data had been collected over a period of 16 years (2003 - 2019) in order to analyze spatio-temporal variation. Groundwater levels are plotted on a base map with their respective amount of depths, and then the contours of equal values are drawn using Inverse Distance Weighted (IDW) method in ArcGIS. The final results are helpful in preparing for shortage and seeking alternatives if need arises from study report.
