Applying the HSPF Model to Predict Watershed Responses Under the Impact of Climate Change
The objective of this study is to identify the changes in rainfall characteristics and to predict the possible environmental responses in the Shihmen Reservoir watershed in Taiwan under the climate change scenario. These objectives are made possible by looking at officially released rainfall projection data in Taiwan, and by applying the Hydrological Simulation Program-Fortran (HSPF) model, which is used to simulate hydrologic responses and diffuse pollution projections. The results show that while the change of annual precipitation is not obvious, seasonal variation and intensity of rainfall increase under the climate change scenario. Furthermore, the increase of rainfall intensity during certain seasons enlarges landslide areas and increases environmental vulnerability. Compared to diffuse pollution, the impact of climate change on hydrologic responses is difficult to control. Therefore, disaster management continues to have critical importance in achieving sustainable environmental management.
