Abstract
The study covers the groundwater level variability analysis and its relationship with rainfall for the Hebballa watershed of Mysore district, Karnataka. Through Geographical Information System (GIS) technique. The rainfall data from the study area for a period of ten years were analyzed annually and categorized based on the seasons: Pre monsoon Jan to march , Southwest monsoon (Jun. to Aug ),Northeast monsoon (Oct. to Dec.). By conventional method, the annual rainfall is found to be 1446mm, of which the post monsoon, pre monsoon, SW monsoon and NE monsoon are 298.mm, 2274mm,and 784.10mm average rain fall received respectively. These results were taken into GIS platform and the spatial distribution maps prepared. From these spatial distribution maps for the seasons, annual average rainfall was prepared. The maximum rainfall was recorded at Harohalli 71.80%, having the monthly and annual average respectively. Similarly the minimum rainfall was at Dharmapuri in 61% average value. The monthly rainfall curve has its peak during October and nadir during January. SW monsoon and NE monsoon almost play an equal role in their rainfall contributions, whereas the post monsoon rainfall occurrence is negligible in this region Gangadhara G | Dr. Subash. S.
