| Zusammenfassung |
| The occurrence of typhoon Herb in 1996 caused massive landslides in the
Shenmu area of Taiwan. Many people died and stream and river beds were
covered by meters of debris. Debris flows almost always take place in the
Shenmu area during the flood season, especially in the catchment areas
around Tsushui river and Aiyuzih river. Anthropogenic and natural factors
that cause debris flow occurrences are complex and numerous. The precise
conditions of initiation are difficult to be identified, but three factors
are generally considered to be the most important ones, i.e. rainfall
characteristics, geologic conditions and topography. This study proposes a
simple and feasible process that combines remote sensing technology and
multi-stage high-precision DTMs from aerial orthoimages and airborne LiDAR
with field surveys to establish a connection between three major occurrence
factors that trigger debris flows in the Shenmu area. |
