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. WebTherefore, the cell with the largest peak inundation depth in the model simulation results under each scenario was selected for analysis . As can be seen from Figure 10 , when the recurrence period is 10 and 20 years, the modern land-use scenario takes the least time to reach the peak inundation depth, followed by the land-use scenario of the ...
