中小河流的洪水演进模型构建往往受到河道地形数据的制约.通过无人机和遥感构建的精细化数字地形,构建了浊漳河干流的甘村-上遥镇河段洪水演进模型,模拟该区域多年一遇的洪水演进情况.结果表明:流量越大洪水演进越快,淹没范围越大;断面流量与淹没范围的关系密切,流量小积累洪水易形成淹没;十字道村及北底中学河段淹没风险最大.
Numerical Simulation of Flood Evolution in Gancun-Shangyao Town Section of Zhuozhang River Based on Refined Terrain
The construction of flood evolution models for small and medium-sized rivers is often restricted by river terrain data.Through the refined digital terrain constructed by drones and remote sensing,a flood evolution model for the Gancun-Shangyao town section of the Zhuozhang river was constructed to simulate the evolution of multi-year floods in the area.The results show that:the greater the flow,the faster the flood evolution and the larger the inundation range.The cross-sectional flow is closely related to the inundation range,and small flow accumulation floods are prone to inundation.The flood risk of Shizidao village and Beidi middle school is the greatest.
