Model Outputs: The outputs provided by the model are very extensive, covering all the components of water balance spatially and temporally. The sub components of the water balance that are most significant and used for analyses, include: o Precipitation o Total flow (Water yield) consisting of surface runoff, lateral and base flow o Actual evapotranspiration (Actual ET) 194. Mean annual and seasonal precipitation is shown in Figure 55, and the coefficients of variation in Figure 56. Most precipitation occurs during the southwest monsoon and coefficients of variation during this period are significantly lower than during the northeast monsoon. 89

Simulation with A1B baseline: Prior to analysis of climate change scenarios, and assessment was made how well the characteristics of SWAT streamflows simulated from the PRECIS A1B baseline weather, matched with those simulated from observed weather. Figure 57 presents a comparison of mean monthly discharges at Ujjain and Mahidpur simulated from observed weather and 90
