摘要: Climate change would significantly affect the water resources system globally as well at basin level. Moreover, future changes in climate availability, run-off, and flow of river. This study evaluates impact possible scenarios on hydrology catchment area Citarum River Basin, Indonesia. The evaluation planning (WEAP) tool was used for hydrological modelling area. statistical downscaling model (SDSM) to downscale daily temperatures precipitation four sub-catchments global variables A2 B2 obtained from Hadley Centre Coupled Model version 3 (HadCM3) used. After calibration testing procedure, streamflow evapotranspiration (ET) were projected three periods: short term (2010–2039), midterm (2040–2069), long (2070–2099). impacts are assessed by comparing present estimated ET. temperature is increase future. results balance suggest increasing run-off potential ET losses over sub-catchment
