Abstract/Description: | The average annual rainfall of 887 mm in the Kollur sub-watershed as recorded from the Hattikuni station data. 80%, 12% and 8% of the annual rainfall occurs during kharif, rabi and summer seasons respectively and exhibited a higher temporal variability. The evapotranspiration estimation tool developed indicates that the watershed water balance is in sustainable condition. The estimated runoff available to use is 33 mm for an average annual rainfall of 830 mm (2009-2017). The utilizable groundwater is 49.7 mm (70% of 71 mm recharge estimated). This means the total available water resource combining the soil moisture store for kharif & rabi (136 mm) and utilizable runoff plus recharge is 219 (=136+33+50) The average actual evapotranspiration estimated in the watershed based on the current land use and irrigation practices for the kharif and rabi seasons is 522 mm. Hence the amount of water use for kharif and rabi seasons may be estimated as 652 mm (i.e 125% of AET). This demand for the two seasons is higher by 433 mm, i.e. (652-219). The AET in June-Sept months is only 49% of rainfall. Hence, there is a good opportunity to harvest the excess water through watershed management practices for utilizing during rabi season. The total number of wells present in Kollur Sub-watershed as per LRI data is 10 Bore wells. The groundwater level data obtained from Dept. of Mines & Geology for the nearest station Yergol. The groundwater level during the years 2011-2017 were slightly varying, where as during the year 2014 was found constant |
