The inventory and documentation of spatial and temporal changes in hydrological components of Hebbur Micro-Watershed (4D3E4P2b) in Tarikere Taluk, Chikkamagluru District, has been undertaken for integrated planning, development and management. Hebbur Micro-Watershed is located between 13º 46ʹ 14.81ʺ N to 13º 44ʹ 23.95ʺ N Latitude and 75º 58ʹ 24.38ʺ E to 76º 0ʹ 41.14ʺ E Longitude, covering an area of 1038 ha. The Micro-watershed falls under Ajjampura (4D3E4P) Sub-Watershed. Hydrological assessment of basic parameters namely, rainfall pattern, relations among PET, AET and rainfall, soil moisture change, mapping unit wise runoff generation and change in ground water status are presented in the paper which will help in making decisions regarding, cropping choices, artificial recharge and improved harvesting operations and conservation structures. Average annual rainfall of the area is 874 mm. Budyco curve analysis showed that watershed is not under sustainable condition. The mean annual rainfall recharge factor found approximately 16 percent. The groundwater use for irrigation is higher in the upper regions of the watershed and hence artificial recharge and harvesting operations should be taken up in the higher bore well density areas in the upland parts of the catchment.
