Abstract：Shandong Province currently has 5,241 small reservoirs,mostly distributed in hilly areas.Once a major danger situation that may cause dam break occurs,insufficient preparation,inadequate measures,and untimely emergency rescue will seriously threaten the lives and property of downstream people.To analyze the impact of dam-break floods from small reservoirs in hilly areas,this paper takes the Sanba Reservoir in Zouping,Binzhou as an example,constructs a two-dimensional dam-break flood numerical simulation model,simulates the flood evolution process under the condition of over-standard flood overtopping and instantaneous dam break,analyzes the impact of dam-break floods at different moments on downstream commercial areas,residential areas,and major infrastructure,and calculates the inundation area,flow velocity,and peak arrival time of the dam-break flood.The research results can provide reference for flood control project construction and non-engineering measure management,facilitate maximizing the comprehensive benefits of flood control projects and hold primary significance for flood control and disaster mitigation.
