Optimization of a flood diversion gate scheme in flood storage and detention areas based on flood numerical simulation
Abstract
Flood storage and detention areas are an important aspect of the river flood control system and an effective measure to ensure flood control safety and mitigate disasters in key areas. Using the flood storage and detention area of DaHuangPuWa as an example, the flood diversion evolution of different positions on the Jinbao highway was simulated numerically. The water level, velocity, and flow rate of each observation point during the 100-year flood were calculated. After comprehensive analysis, it is determined that the location of the diversion gate in the flood storage and detention area is better at the diversion gate of Liuwanzhuang. The results of this paper show that the numerical simulation method can provide more scientific and reasonable theoretical support for the design of flood diversion gates in flood storage and detention areas.
