The Floodwater Depth Estimation Tool (FwDET) calculates floodwater depths using a digital elevation model (DEM) and a flood extent polygon shapefile. Within this repository resides the three versions of FwDET. Version 1, featured in Estimating Floodwater Depths from Flood Inundation Maps and Topography [Cohen et al. 2018], best works in inland riverine regions and has been implemented using both Arcpy and QGIS. Version 2, features an improved algorithm which better solves coastal flooding as well as fluvial [Cohen et al. 2019]. Version 2 implements a much different approach that is considerably more computationally efficient, drastically reducing run time compared to version 1 of the tool. Version 2.1 introduces a boundary cell smoothing and filtering procedure whicn improves the tool's accuracy.
