| dc.description.abstract | The SWAT model applied in the Kikafu River Sub-catchment, with a catchment size 2, | # of 208.32 km to simulate the river flow and to estimate water resources available in the catchment. The catchment experiences over abstraction of water by upstream users, which reduce water availability to downstream users especially during dry season. There is no meteorological station in the catchment, thus weather data of the nearby meteorological station was applied to setup the model. The weather generator (WXGEN) SWAT’s model built in tool was used to fill missing weather data. Three methods were used to fill 42% missing observed records of the Kikafu River flow gauged at 1DD8A that was used to calibrate the SWAT model. Sensitivity analysis of 27 SWAT’s hydrologic parameters showed that 11 parameters revealed meaningful effects to flow simulation. Manual calibration for the 1999-2004 in daily basis gives satisfactory results with NSE of 56.58% and R2 of 65.14% while the NSE of 51.64% and R2 of 73.27% for the 2005-2006 validation period. The estimated water balance in the Kikafu River Sub-catchment have total annual rainfall of 759.3 mm, 55.18% lost as evapotranspiration, while surface runoff, groundwater, and change in soil moisture storage accounts 42.55%, 1.70%, and 0.57% respectively. The water yield/river flow is 42.65% of the total annual rainfall. From the available hydro-climatic data in the Sub-catchment the developed SWAT model can be useful tool to estimate daily Kikafu River flow and the associated hydrological assessment. The model performance can be improved by including closer climatic stations surrounding the Sub-catchment, introducing imaginary climatic stations within the Sub-catchment, and Sub-catchment regionalization | en_US |
