摘要

为提高溃坝洪水风险分析的实时性并适应洪水演进的动态特征，设计了一种基于B/S架构的三维实时洪水风险分析系统。该系统采用BREACH溃口流量计算软件与二维水动力数值模型耦合的方法进行溃口洪水计算及洪水演进模拟，并结合WebSocket技术实现数据的实时传输，利用Cesium三维可视化平台展示洪水演进过程。系统核心功能模块包括溃坝洪水方案管理、实时计算及计算结果分析，可支持溃坝过程的动态管理、实时计算和结果展示。通过某水库案例对系统进行了应用验证，结果表明，该系统可有效反映洪水淹没过程，计算结果合理，并能够通过可视化技术提高洪水风险分析的直观性和决策支持能力。

Abstract

In order to enhance the real-time capability of flood risk analysis and adapt to the dynamic characteristics of flood evolution

a 3D real-time flood risk analysis system based on the B/S architec⁃ ture has been designed. This system employs a coupled approach of the breach flow calculation software BREACH and the 2D hydrodynamic numerical model for dam-break flood calculation and simulation. It integrates WebSocket technology for real-time data transmission and utilizes Cesium 3D visualization platform to display the flood evolution. The core functional modules of this system are scenario manage⁃ ment

real-time calculation and calculation result analysis of dam-break flood

which can support dy⁃ namic management

real-time calculation and result visualization of the dam-break process. The system was validated through the case study of a reservoir. The results showed that the system can effectively re⁃ flect the flood inundation process

obtain reasonable calculation results

and enhance the intuitiveness of flood risk analysis and the decision-support capability through visualization technology
