Dampak Perubahan Penggunaan Lahan terhadap Tingkat Kekritisan Air Sub-DAS Citarum Hulu

Research output: Contribution to journalArticlepeer-review


The population growth and the need for living space have changeq the patterns of land use especially in Upper Sub Citarum Watershed as one of the critical watersheds in Indonesia. The changes in land use will result in the reduction of water resources and make the higher level of water criticality. Data used in this research including river network map, landuse map obtained from Indonesian National Land Agency (BPN), precipitation and temperature data of 1975-2005, soil map, slope map, vegetation cover and primary water demand data. The critical level of watershed is deterimined based on the comparison of primary water demand and water availability in Upper Citarum Sub Watershed. Through GIS method combined with hydrological approach, the areas of sub watershed experiencing water shortage, in this case is water critical level can be determined. The combination of GIS method and a hydrological approach has resulted in sub-catchment areas experiencing water shortages in this case the critical water level.
