|
Abstract:
After Wenchuan earthquake,Niumiangou valley becomes an area with dense and frequent debris flow disasters;so far,seven large-scale debris flows occurred.In this valley there are three basic conditions making debris flow well develop, and so it is in a developing stage now.Thus the large-scale rainfall induced debris flow disasters,with large damage and stronger wallop,will easily occur in the 5-10 year after earthquake.If considering to use directly the debris flow deposit in the main gully of Niumiangou va...
