摘要

在减少洪水风险的过程中，洪水危险地图的可用性是有益的。然而，缺乏高分辨率的地形数据，这是地图实现的障碍。因此，本研究旨在根据不同洪水重现期的危害程度构建洪水危害图。水文工程中心河流分析系统（HEC-RAS）的2D流体动力学和无人机（UAV）图像的数字表面模型（DSM）用于生成淹没地图。结果表明，对2年和10年重现期的模拟表明，洪水风险水平增加了37%。此外，受洪水淹没的地区的危险程度也有所增加。这种情况发生在住房、一些道路和稻田中。最终，本研究通过确定疏散方向、城市空间规划和明智的防洪措施来缓解洪水危害。

Flood hazard mapping of the Welang river, Pasuruan, East Java, Indonesia

The availability of a flood hazard map is beneficial during flood risk reduction. However, there is a lack of high-resolution topographic data, which is a map realization obstacle. Therefore, this study aims to construct flood hazard maps based on hazard levels for various flood return periods. The 2D-hydrodynamic from the Hydrologic Engineering Center's River Analysis System (HEC-RAS) and Digital Surface Models (DSM) from Unmanned Aerial Vehicle (UAV) imagery were used for generating inundation maps. The results showed that simulation of return periods for 2 and 10 years illustrated a 37% increase in flood hazard levels. Furthermore, there was an increased danger level for locations that were exposed to flood inundation. This occurred in housing, some roads, and rice fields. Ultimately, this study mitigates flood hazards through the determination of evacuation directions, urban spatial planning, and informed flood mitigation measures.
