Abstract:
Water resources availability for meeting reservoir storage, water supply diversion and environmental in stream flow requirements must be assessed on various premises regarding future water used as well as climatic and hydrometeorological conditions. This study, therefore, investigates temporal dynamical model and detects persistence and plausible long-term trends of the hydrometeorology in the Upper Citarum River Basin, West Java, Indonesia. The investigations based on monthly observations data of the rainfall, evapotranspiration, humidity, and runoff from January 1968 to December 2000 and monthly global phenomena data from National Centers for Environmental Prediction (NCEP). Identification of the temporal dynamical model of the hydrometeorology based adaptive neuro-fuzzy inference system (ANFIS). The conclusion obtained in this study shows that temporal dynamical model of the hydrometeorology based on ANFIS can simulate the observations accurately. The model is capable to minimize the bias and root mean squared error (RMSE). The rainfall, evapotranspiration, and humidity had two firm persistence i.e. wet and dry periods, while the runoff has no firm persistence. The rainfall and runoff had been decreased by about -3.64% and -1.11% respectively. On the other hand, the evapotranspiration and air humidity had been increased by about 3.88% and 4.21% respectively. The results of these studies can give an information for improvement of an integrated water management in the Citarum river basin.
