摘要
蓄滞洪区是防洪减灾体系中的重要组成部分,研究蓄滞洪区破口后洪水演进过程对灾害避险规划以及保障工程安全具有重要意义。基于无人机倾斜摄影技术快速获取研究区域密集点云数据并构建三维模型,利用高精度DEM数据构建二维水动力数学模型,对洪水影响区各处的洪水到达时间、水位变化过程、淹没深度、淹没面积进行比较分析。
The flood storage and detention area is an important component of the flood control and disaster reduction system.Studying the flood evolution process after the breach of the flood storage and detention area is of great significance for risk avoidance planning and ensuring engineering safety.Based on unmanned aerial vehicle tilt photography technology,dense point cloud data in the research area is obtained quickly and a three-dimensional model is constructed.High precision DEM data is used to construct a two-dimensional hydrodynamic mathematical model,and comparative analysis is conducted on the flood arrival time,water level change process,inundation depth,and inundation area in various flood affected areas.
