Flood Disaster's Integrated Risk Evaluation and Strengthening Decision Research for Group of Reservoirs in Changtai Creek Basin

摘要

Based on the results of safety identifications and socioeconomic investigations for 10 minitype reservoirs in Changtai river basin, east of china, their respective risk analysis,wreck consequence assessment, and flood disaster risk estimation had been performed. Fur-thermore, the group of reservoirs had been abstracted into a directional system, which the transmission, diversion, and accumulation effect of flood disaster risk, even the system's re-action to one or more dam-failure events could be meditated. When the interaction of reser-voirs has been considered, the group of reservoirs' integrated risks evaluation model would be finally established. And then according to the model, each several dams' strengthening priority level in the system could be collated, which could be looked upon as foundation of strengthening decision.
