Three land-use scenarios (current: 2014 LU-Ls8, future: 2025 LU-Pm, and future: 2025 LU-Pop) were generated and analyzed for hydrologic modelling. The Global Climate Model: MRI-AGC M3.2S5containing 1979-2003 and 2075-2099 daily precipitation data was used to model the outflow in the subwatershedunder the three different land-use scenarios. Outflow volumes were generated for the 24 year-past (1979-2003) simulation and 24 year-future (2075-2099) prediction. The daily rainfall average was used to run the model for 365 days or one year (GCM down-scaling). Result from this study will be used as input to derive the flood extent in the downstream of the subwatershedto see the effect of the future precipitation in the area.
