Future Impacts of Climate Change on Streamflow and Sedimentation of Merawu Catchment, Indonesia
Watershed Laboratory, Department of Forest Resources Conservation, Faculty of Forestry Universitas Gadjah Mada, Yogyakarta 55281, Indonesia
A study was conducted to assess the impact of climate change on the Merawu Sub-watershed in Indonesia, particularly in relation to the planned development of Indonesia Emas 2045. The sub-watershed is vulnerable to climate change due to the lack of proper soil and water conservation practices and the presence of a hydropower plant downstream. The study utilized the SWAT model to build a hydrological model and used data from GCM scenarios to analyze climate change and its impacts in 2035-2045. The results showed that there will be an increase in rainfall and a decrease in maximum and minimum temperatures in the sub-watershed during this period. The model indicated an increase in streamflow by 110.1% to 207.4% and sedimentation by 445.7% to 699%. The study highlights the need to address these changes to mitigate the risks of disasters and losses due to climate change in the Merawu Sub-watershed.
