NOTE: the Stream Channel and Floodplain Metric Toolbox has been superseded by a newer tool, FACET. The Stream Channel and Floodplain Metric Toolbox was developed to demonstrate the feasibility of mapping fluvial geomorphic features from high-resolution bare-earth elevation data. A Python toolbox for ArcGIS was built to calculate key metrics describing channel and floodplain geometry. Channel and Floodplain Metric Toolbox provides this ability in an automated fashion, allowing for regional analyses based solely on digital elevation models (DEMs). This manual describes the general operation of the toolbox and technical details describing the specific algorithms. The toolbox works best in a watershed no larger than...
Datasets used to quantify and value the ecosystem service of sediment and nutrient retention for floodplains within the Difficult Run watershed located in Fairfax County, Virginia. Geospatial datasets include a digital elevation model (DEM), a hydrologically conditioned DEM, output from the USGS Stream Channel and Floodplain Metric Toolbox, and field data sets used to develop regression models to predict sediment and nutrient retention services for stream within the Difficult Run watershed.
