This study aims to identify changes land use between river sub-watersheds in the period 2000, 2010 and 2020, This study uses an ecological approach, political economy, with map overlay analysis (superimpose) and Geographic Information System provides information on changes land use and area of surface waterlogging. The results of this study describe changes land use from land cover to built up land so that the increase in surface water inundation is due to reduced absorption of surface water into the soil between the White River and Selayang River sub-watersheds and estimates the next 5 (five) years from the projected effect of changes in land use. land use against waterlogging between the White River and Selayang River sub-watersheds
