Development Characteristics and Flow Calculation of Loose Soil Debris Flow in Arid Valley-A case Study of Debris Flow in Karsiyagou,Aksu,Xinjiang
Aksu Karsiya gully is located in the north of Wensu County,Aksu City.It is composed of a large scale debris flow in the mountain area and the river gully in the foreshore flood plain,which is a typical arid debris flow.Debris flow occurred several times in the ditch,causing great losses.In order to find out the development characteristics of debris flow in Karsiya Ditch,the central government funded a special investigation in 2020.Based on field investigation and measurement,the geological environment,regional characteristics and formation conditions of debris flow disaster in Karsiya Valley,Aksu,Xinjiang were ascertained,the danger area of debris flow was delimited,the peak flow of debris flow was estimated,and the development trend was predicted.It provides the basis for the design and construction of prevention and control engineering.
