Dynamic spatio‐temporal flow modeling with raster DEMs

A user-friendly high-resolution intermediate complexity dynamic and spatially distributed flow model is crucial in urban flood modeling. Planners consultants need to improve the accuracy of floods estimation risks. new will serve as a rapid tool identification these. This article provides detailed explanation based on multiple algorithm. Model testing was performed selected rural areas. Additionally, sensitivity analysis conducted analyze functionality. The includes basic hydrological processes therefore less complex than fully physical models. data needed set up run include temporally geometric hydrologic variables (i.e., digital elevation model, precipitation, infiltration, surface roughness). implemented using open-source coding can easily be applied any area. Outputs are water volumes, depths, velocities at different modeling times. Using GIS, results visualized utilized for further analyses. test, well areas, demonstrates its user-friendliness, that estimated depths velocity time step saved visualized.
