Program of Determination Fit Reservoir in Indonesia Under Climate Change Scenario

Indonesia is a tropical archipelago with average annual rainfall about 1755 mm and negligible transboundary water resources. Current national water use is ~ 7,759 m3/s, which represents only 1.4 % of available water in Indonesia. However, there has been a recent shift in rainfall patterns in several regions of Indonesia. Strengthening of climate variability has been predicted as a consequence of climate change, but as of 2012, there has been only minimum climate change adaptation in Indonesia, especially in water management. Almost all rainfall flows to the sea without storage in reservoirs. The objective of this research is to develop a program for determining the best location of a reservoir in an upper watershed under climate change scenario type B2. This program is integrated with SWAT and designed as an extension that is dockable to ArcGIS 9.x.
