Global climate change causing significant changes to the existing water supply. This of course requires good management of water allocation and effective for each region of the water users. Distribution of water between upstream-downstream water users and between sectors should be allocated in such a way as to be able to do the right response and adaptation to climate change in order to obtain justice and the optimal and sustainable benefits. Based on the study it was necessary to analyze the impact of climate change on water availability in the river basin and how the management of water allocation should be done in order to provide recommendations or solutions to the current condition of water allocation as well as how future scenarios of water allocation. In this study expected to provide answers to the needs of the meteorological analysis of climate change associated with the next rainfall will affect the variables associated with water balance <br /> <br /> <br /> system and an integrated water management. Analysis performed within this study include monthly rainfall analysis to determine the trend of rain that occurred, the analysis of climate change from the rain with different scenarios using MAGICC SCENGEN, analysis of rainfall runoff with NRECA and the latest methods of analysis of water allocation in the Upper Citarum watershed Based on this analysis, in the upper Citarum watershed showed the trend of climate changes indicated a decrease in the amount of rainfall from year 1916 to 1988. However Analysis SCENGEN MAGICC rain value that can be said is optimistic for the future. NRECA calibration results to get the Upper Citarum watershed scale the average absolute error of 31% that can be said is sufficient to discharge in the future projections. <br /> <br /> <br /> While the analysis of water allocation in the Upper Citarum watershed period in 2030 resulted in the discharge of 80% which will be smaller with a more long-long drought. Thereby shifting the planting season which happens to be anticipated.
