洪涝灾害的快速模拟及预警预报是洪涝防灾减灾的重点,但目前基于物理机制的城市洪涝模型的模拟时效仍然过低。通过结合水动力模型模拟生成的洪水淹没数据和深度学习技术,构建基于卷积神经网络(CNN)的深度学习洪水模拟模型,对城市洪水淹没演进情况进行快速模拟。结果表明,所构建的CNN模型能较好地模拟洪水淹没的演进情况,预测峰值水深误差在8%以内,对淹没范围模拟效果良好。CNN模型具有极高的洪水淹没模拟效率,在保持和水动力模型近似精度的同时,计算效率可提升约400倍。研究结果可为流域与城市洪水淹没快速模拟、洪涝灾害预警预报和数字孪生流域建设等提供技术支撑。

[ Objective] The research aimed to establish SWAT distributed hydrologic model and analyze influence of the climatic change on runoff in Beijiang River basin. [ Method] Beijiang River basin as research object, SWAT model was used to simulate runoff in basin. Monthly water flow in Shijiao station from 1961 to 1980 was used to determine model parameter, while monthly water flow from 1981 to 1990 was used to verify. Setting 15 kinds of climate change scenarios, SWAT model was used to simulate influence of the future climatic change on runoff in Beijiang River basin. [Result] Simulated accuracy of the SWAT model was high, and it could be used to simulate runoff in Beijiang River basin. Under the situation of in- variable rainfall, temperature rise made that evaporation capacity increased, and runoff depth decreased. When temperature unchanged, rainfall increase made that evaporation capacity and runoff depth increased somewhat. [ Conclusion] The research could provide reference basis for water re- source management in Beijiang River basin.
