Abstract
The risks associated with cascade reservoirs in river basins have the effects of transmission and accumulation,and the simulation of flood evolution under the condition of consecutive collapses is crucial for flood risk management and emergency decision-making.Liuxihe Reservoir in Guangdong Province is an important water conservancy project in Guangzhou,adjacent to Huanglongdai Reservoir.If Huanglongdai Reservoir collapses,it may lead to instability of the auxiliary dam,further causing consecutive collapses of the reservoir,posing a significant threat to the lives and property of people downstream.This study utilizes the DL-BREACH and HydroMPM models to construct a model of consecutive collapses of the two reservoirs,calculates the changes in breach flow and the downstream flood evolution process,analyzes the inundation impact of the dam collapse flood on the downstream areas,and provides support for flood risk management in the river basin.关键词
