泄洪道

Prof Hughes said natural dams formed by landslides were potentially much more dangerous and unpredictable than man-made dams, because they were random lumps of hillside rather than carefully engineered structures with spillways to carry away excess water.

休斯表示，由于山体滑坡形成的天然大坝只是随意堆砌的一块块山石，而不是精心建造并配备泄洪道的人工结构，其危险性与不可预知性有可能远远超过人工大坝。

The torrent picked up buildings, animals, and human beings and sent them crashing down the spillway.

洪水沿路夹带建筑物残骸 、 动物及人进入泄洪道.

Local government just introduced a new set of spill control devices.

The spillway cannot be blocked, otherwise it will cause a serious problem.
