    Abstract

    Climate change and deforestation cause runoff discharge going to increase. Land cover change decrease infiltration, so when rainfall happen, water directly transformed to runoff. It is interesting to do some research about the effect of soil cover change to runoff. This is a Descriptive Quantitative research using rainfall stasion coordinates as primary data and daily ranfall and Keduang Sub-Watersed geographic map as secondary datas. In this research, Keduang sub-watershed divided to several square 1x1 km grids. Using MPAR, there are 8 land cover change scenarios applied in upper, middle, and lower zone of Keduang sub-watershed. Then, the simulation results compared with observed data to know how much land cover change affect the runoff. As results, there is 16,85% difference of total volume and 5,27% difference of peak discharge on upper zone land cover change, 18,29% and 8,2% on middle zone change, 17,08% and 4,12% on lower zone change, and 20,07% and 9,8% difference on total Keduang sub-watershed change. Keywords: Grid, land cover, runoff.
