Hazard Assessment of Debris Flows in the Reservoir Region of Wudongde Hydropower Station in China

Hazard Assessment of Debris Flows in the Reservoir Region of Wudongde Hydropower Station in China

The outbreak of debris flows in a reservoir region can affect the stability of hydropower stations and threaten the lives of the people living downstream of dams. Therefore, determining the hazard degree of debris flows in a reservoir region is of great importance. SPOT5 remote sensing images and di...

Therefore, determining the hazard degree of debris flows in a reservoir region is of great importance. SPOT5 remote sensing images and digital elevation models are introduced to determine the characteristics of debris-flow catchments. The information is acquired through comprehensive manual investigation and satellite image interpretation. Ten factors that influence debris flow are extracted for the hazard assessment. The weight of these factors is determined using the analytic hierarchy process method. As a multi-criterion decision analysis method, fuzzy synthetic evaluation is applied for hazard assessment.http://www.mdpi.com/2071-1050/7/11/15099debris flowSPOT5digital elevation modelanalytic hierarchy processfuzzy synthetic evaluationhazard assessment
