| Zusammenfassung |
| In the recent years, the rapid climate change due to global warming caused much serious and
more heavy rainfall events than before in Taiwan. Sometimes, the extreme flood may cause
the failure of hydraulic constructions. For example, Baling Sabo-Dam in Shihmen Reservoir
watershed was broken due to the typhoon flood during typhoon Wipha in 2007. Tremendous
sediment storage by the sabo-dam was free to flush downstream and the riverbed was varied
significantly. This paper discussed the phenomenon of sabo-dam break through a serious
of dam break experiments. The bed materiel of sand was released in a dedicated
flume equipped with a fallen gate and no bed materiel was deposited downstream of
the gate. Several characteristic behavior were also discussed by changing the flow
discharge and channel slope. However, a pivot point of the sand bed was observed
which was different from the dam-break wave cases of 4/9. the location of pivot
point , the headward erosion and the depostion downstream were also discussed. |
