小流域堰塞湖对山洪泥石流的调控模式探讨
Discussion of regulation mode of torrent-debris flow by dammed lake in small river basin
摘要
Abstract
Through the detail investigation and analysis on dammed lakes in small river basin in the east of Tibetan plateau, the first tributary Haizi gully of the Jinsha River in Qiaojia County, the first tributary Zongqu gully of the Minjiang River in Maox-ian County, and the second tributary Gucheng gully of the Minjiang River in Lixian County are selected as typical cases to study the regulation mode of torrent-debris flow by dammed lakes in small river basin. There are three mutual transformation modes of torrent and debris flow under the regulation of dammed lakes:the torrent-debris produced by deposit and re-erosion, the deb-ris deposited and clear water discharged, and erosion scale enlarged. Based on the regulation mode of small watershed dammed lakes on the torrent-debris flow, the disaster risks of the dammed lakes with different characteristics are revealed, and some tar-geted measures are proposed.关键词
