CLIMATE CHANGE AND ITS IMPACT ON GROUNDWATER TABLE FLUCTUATION IN PRECAMBRIAN TERRAIN OF CHITRADURGA DISTRICT, KARNATAKA, INDIA USING GEOMATICS APPLICATION
The study area falls within the semiarid region and frequently facing water scarcity problems. Rain is a form of precipitation, snow, sleet, hail and dew. The precipitation occurs when separate drops of waterfalls on the earth’s surface from clouds. Not all rain reaches the surface, however; some evaporates while falling through dry air, a type of precipitation called Virga. The precipitated water percolates to deeper zones to be stored as groundwater. The present study generates the primary data to map the groundwater table fluctuation in hard rock terrain of Chitradurga District
through Geomatics technique. Efforts have been made to evaluate a total of 20 representative rain gauge station samples and analyzed the season rainfall variation over a period of 31 years (1981- 2011). 47 representative well samples are collected to study the season-wise groundwater fluctuation of about 11 years (2000-2011). Rain gauge stations are plotted on a base map with their respective amount of rainfall.
