Abstract
In conventional research, precision forecasting of slope failures during heavy rainfall using critical rainfall line is not so accurate, because it used only rainfall factors for forecasting. In this research, the slope failure prediction system using both rainfall factors and geomorphological factors is constructed based on multiple discriminate analysis. Then we determined the critical rainfall line and try to improve the precision forecasting. The result shows that the precision had improved more than 80% in forecasting.
