Abstract:
Greater Bandung lies on the heart of upstream part of biggest water catchment in West Java with abundant of water resources. However, it is facing an imbalance in supplying its water demand, due to population growth concentrated mostly in urban center. Consequently, it forces to provide the water supply from its outskirts using reservoir which additionally should be able to cope with climate variability. This study is aimed to understand the trend of water availability in greater Bandung and applying such trend towards a hypothetical reservoir. The performance of the hypothetical reservoir will be evaluated using reservoir simulation. The result shows that there is a downward trend of monthly rainfall trend in greater Bandung. The annual down rates for dry and wet season are 16% and 10%, respectively. Consequently, the utilization of reservoir in the upper area of the study demonstrates only 82% of success rate to supply the water in urban region, which is lower than recommended rate.
