Geomorphometry for Streams and Floodplains in the Chesapeake and Delaware Watersheds
May 5, 2020
Geomorphometry for Streams and Floodplains in the Chesapeake and Delaware Watersheds was generated as part of the project Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed funded through the William Penn Foundation's Delaware Watershed Research fund. This dataset contains geomorphometry for streams and floodplains in the Chesapeake and Delaware River watersheds. Geomorphometry is a quantitative representation of landscape surface form (e.g., channel width and depth) obtained from digital elevation models (DEMs). The dataset contains geomorphometry derived from running 3-m DEMs through the Floodplain and Channel Evaluation Tool (FACET) version 0.1.0. FACET generates shapefiles and rasters of the stream network, cross sections, streambank point locations, floodplain extent, height above nearest drainage (HAND), and reach-scale summaries of bank height, channel width, floodplain width, and a suite of other metrics outlined in the data dictionary. These data were generated to aid in modeling the amount of sediment and nutrients trapped on floodplains or eroded from streambanks in the Chesapeake and Delaware River watersheds.

Mapping stream and floodplain geomorphometry with the Floodplain and Channel Evaluation Tool
Broad-scale mapping of stream channel and floodplain geomorphic metrics is critical to improve the understanding of geomorphic change, biogeochemical processes, riverine habitat quality, and opportunities for management intervention. The Floodplain and Channel Evaluation Tool (FACET) was developed to provide an open-source tool for automated processing of digital elevation models (DEMs)...
