 # Floodwater Depth Estimation Tool
 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 two versions of
+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. 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.
 
-FwDET can be executed either as a standalone Python script or via a toolbox in
-ArcMap (v1 & v2) or QGIS (v1). Version 1 and 2 have been implemented via Arcpy
-scripts and Arc Toolboxs with version support for >= ArcGis 10.5 and ArcGis Pro.
-Version 1 also has both a standalone and plugin open-source QGIS version, that

-scripts are located under [fwdet/source](fwdet/source).
 
 ## How to use FwDET ArcMap/Pro Toolbox
 1. Clone this repository or download the 
 [toolbox file](fwdet/FwDET.tbx).
 2. Open ArcMap/Pro and navigate using the catalog to the directory
-   containing `FwDET.tbx` or `FwDET_ArcGISPro.tbx`.
+   containing `FwDET_ArcGISPro.tbx`.
 3. Expand the toolbox and double click on the tool version you wish to
    use.
