Abstract
Taiwan middle area geology environment
quite complex, in addition earthquake and
the typhoon are quite frequent, creates the
locality frequently to have the landslide and
the Debris flow. Since Herb typhoon result to
Debris flow in Chenyoulan watershed, has had
the Lanxi area to celebrate the primary
typhoon to have the disaster situation,
through repeatedly 921 earthquakes, the
peach irises typhoon and the many times
torrential rain, already the shape round
number Debris flows the dangerous brook in
the locality. This research mainly aims is
Analysis 15 high dangerous debris flow in
Chenyoulan watershed, carries on the terrain
and the geological analysis, which the
discussion debris flow has the mechanism
and landslide characteristic . The research
technique is carries on by the GIS software
the terrain analysis, including watershed area
and average slope of gully bed characteristic,
and Compared with Debris flow in the
different geological area. We use 921
earthquakes and Toraji typhoon landslide
data discusses the influence to Debris flow.
The results of this research show in the
different geological area, debris flow class
occurs condition is maybe different. Debris
flow because the earthquake and the typhoon
function creates the different landslide area,
can have the varying degree influence to the
debris flow.
