The average annual rainfall of 790 mm in the Kamlapur sub-watershed as recorded from the Kamlapur station data by KSNDMC.
77%, 11% and 12% 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 not appropriate and need to be altered to shift the deficit water balance.
The estimated runoff available to use is 8 mm for an average annual rainfall of 753 mm (2009-2017). The utilizable groundwater is 38 mm (70% of 55 mm recharge estimated). This means the total available water resource combining the soil moisture store for kharif & rabi (139 mm) and utilizable runoff plus recharge is 185 (=139+38+8)
The average actual evapotranspiration estimated in the watershed based on the current land use and irrigation practices for the kharif and rabi seasons is 500 mm. Hence the amount of water use for kharif and rabi seasons may be estimated as 625 mm (i.e 125% of AET). This demand for the two seasons is higher by 440 mm, i.e. (625-185). The AET in June-Sept months is 52% of rainfall. Hence, there is a good opportunity to harvest the excess water through watershed management practices for utilizing during rabi season.
The groundwater level was found from the data obtained from KSNDMC for the nearest station Dongargaon. The groundwater levels during the years 2008-2009 and 2015-2017 was constant. Whereas groundwater levels during the years 2010-2014 were slightly varying. Deepest level was found in the year 2009.
