Basic Characteristics and Risk Assessment of Debris Flow in Plateau Border Villages
摘要
Abstract
As a sudden geological hazard,debris flow is characterized by a wide influence range,rapid outbreak and strong destructive power,and often causes severe damage to the infrastructure of mountain towns and villages.Bayinkuluti Village is located in the alluvial fan area of the gully valley and is highly threatened by debris flow.Therefore,it is of great significance to carry out research on debris flow hazard assessment and prevention in this watershed.To evaluate the basic characteristics and risk of debris flow in Bayinkuluti Vil-lage,Wuqia County,the debris flow gully in the upper reaches of the village was selected as a typical research object,its risk character-istics were analyzed,and corresponding prevention and control suggestions were put forward accordingly.The results show that the gully area in the upper reaches of Bayinkuluti Village has the formation conditions for debris flow occurrence.The loose accumulations in the gully are mainly divided into two types:alluvial-proluvial deposits and eluvial-slope deposits.Among them,Gully No.3 has the largest total volume of mobilizable material source,about 28.7×104 m3.Based on the analysis of peak discharge and the output of solid materi-als,the debris flow in this gully area is determined to be small-scale.For the prevention and control of small-scale debris flow,it is sug-gested to establish a real-time monitoring and early warning system,build check dams in key sections to block solid materials,and con-struct flood discharge channels to divert water flow.关键词
