交替题名	Classification of Debris Flows in the Watershed of Liusha River, hanyuan, Sichuan and Principle of Controlling Them
英文摘要	According to the character of forces causing debris flows and their manifestation the debris flows in the watershed of Liusha River can be classified as Follows: 1. Soil dynamics debris flow, caused by increasing weter content in soil mass or quaking, that increases weight and shear stress of soil mass and reduces its shearing strenght, is made of moving soil mass when its shear stress is larger than its shearing strength. According to its manifestation, it can be subdivided into two types: (1) Landslide debris flow, caused by slipping soil mass which is full of water. (2) Collapse debris flow, caused by collapsing soil mass which is filled with water and located on the top of a steep slope. 2. Hydraulic debris flow, casued by the increase of loose material transported in flow. According to its hydraulic performance, it can be subdivied into two types: (1) Slope wash debris flow caused by raindrops and slope steams washing away ground surface or gully banks. (2) bed wash debris flow, caused by sedment in river bed washed away by flow. According to the characteristics of debris flows and cases in preventing and curing them, the following ways to control them are propsed. They are: 1) to prevent their harm and make use of their advantage, 2) to employ different methods to deal with different types, 3) to work out synthetical plants to control them.
