Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Floodwater Depth Estimation Tool Model type Tool Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Watershed-Scale, Reach-Scale Model domain Terrestrial, Hydrology, Coastal One-line model description Calculate floodwater depth based on an inundation polygon (e.g. from remote sensing) and a DEM Extended model description Allow for quick estimation of water depths within a flooded domain using only the flood extent layer (polygon) and a DEM of the area. Useful for near-real-time flood analysis, especially from remote sensing mapping. Version 2.0 offers improved capabilities in coastal areas.
