Daftar Isi:
- The Bumiaji area is an upstream river basin that has undergone land changes from an undeveloped to a developed area, which may cause a disturbance in the river basin. This research investigates the river basin using secondary data covering land use, land slope, rainfall, and soil types. The quality indicator of a river basin is measured from the quantity of surface runoff. The bigger the scale of the surface runoff is, the lower the quality of the river basin. This research aims to examine the effect of land use changes on the river basin condition, using surface runoff as the indicator. The result shows that the change of land use at Bumiaji affects the surface runoff coefficient and river discharge increment in the Bumiaji river basin. It is concluded that the runoff coefficient (C) increased in sub-river basins one to four, while it decreased in sub-river basin five.
