WebApr 7, 2024 · Terrain representation plays a vital role in flood mapping. For wide area flood simulation where the model grid is typically larger than individual buildings, topography data without ground objects, such as buildings and trees, are preferred as this can generate more accurate inundation simulations than when ground objects are included. WebFlood is a serious challenge that increasingly produce immense economical and ecological damages in worldwide. Flood simulation is gradually becoming a central focus of the hydrology in recent years. It is worthwhile to combine flood simulation with flood damage to infrastructure. The purpose of this study is to develop an approach for better urabn …
