摘要
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。
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 crosssectional 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.
