Potential impact of climate change on inflows to the Batang Ai reservoir, Malaysia

The authors describe a study to determine possible climate change impacts on river inflow at the Batang Ai hydro plant in Sarawak, Malaysia, which will help to assess future annual energy yields for the plant. Five models were used to simulate the daily precipitation over the catchment under two future scenarios. It was projected that for three months of the year, the catchment will receive less precipitation in future, but one month will be wetter under both future scenarios. The average annual precipitation is not likely to change, but seasonal precipitation is likely to shift, it was concluded.
