Short summary
We adopted the projected rainfall coupled with the shallow landslide prediction, debris flow simulation, and loss assessment to investigate the impact in Xindian watershed, Taiwan. Upon comparing the worst events in the late 20th and 21st centuries, the economic losses are projected to increase by 27.8 % due to the increasing disasters on slope land caused by climate change. The influence downstream will be mainly in the form of indirect impacts such as a water supply shortage.
