The average annual rainfall of 631 mm in the Shivpur sub-watershed as recorded from the Hitnal station data by KSNDMC.
71%, 16% and 14% 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 deficit. The cropping & irrigation choices are inappropriate and needed to be altered.
The estimated runoff available to use is 108 mm for an average annual rainfall of 750 mm (2009-2017). The utilizable groundwater is 31 mm (70% of 44 mm recharge estimated). This means the total available water resource combining the soil moisture store for kharif & rabi (106 mm) and utilizable runoff plus recharge is 245 (=106+31+108)
The average actual evapotranspiration estimated in the watershed based on the current land use and irrigation practices for the kharif and rabi seasons is 619 mm. Hence the amount of water use for kharif and rabi seasons may be estimated as 774 mm (i.e 125% of AET). This demand for the two seasons is higher by 529 mm, i.e. (774-245). The AET in June-Sept months is 77% 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 Shivapur Sub-watershed as per LRI data are 15 (9-Borewells & 6-Open wells). The groundwater level was found from the data obtained from KSNDMC for the nearest station Chikkabenakanal. Deepest levels were found in 2017.
