Geomorphic and hydrologic data derived from digital elevation models in Madison County, Tennessee in 2015

Citation

Cartwright, J.M., and Diehl, T.H., 2016, Geomorphic and hydrologic data derived from digital elevation models in Madison County, Tennessee in 2015: U.S. Geological Survey data release, http://dx.doi.org/10.5066/F7D50K20.

Summary

This data release includes spatial datasets and metadata that represent hydrologic and geomorphic information derived by processing digital elevation models (DEMs) for the Pinson Mounds and Upper Sandy Creek study areas in Madison County, Tennessee, in 2015. The processing of DEMs was accomplished using custom-designed GIS tools in the DEM Geomorphology Toolbox. The DEM Geomorphology Toolbox and associated metadata are available for download at http://dx.doi.org/10.5066/F78C9TBQ. Also included in this data release are field notes and field photographs from the Pinson Mounds and Upper Sandy Creek study areas. For detailed descriptions of all data release components, please consult the appropriate metadata document.

Purpose

The purpose of this data release is to present hydrologic and geomorphic information derived by automated processing of digital elevation models (DEMs) for the Pinson Mounds and Upper Sandy Creek study areas in Madison County, Tennessee using tools in the DEM Geomorphology Toolbox. The study that produced this toolbox and this geodatabase was intended to serve as a pilot project to demonstrate the proof-of-concept that DEM-based analysis can be used to estimate geomorphic indicators associated with erosion risk in stream channels. Spatial identification of certain stream-channel geomorphic features may be useful to land managers and water-quality planners seeking to identify locations of sources and sinks of suspended sediment within channel networks. Because DEM-based analysis may require many steps and iterative processes, the usefulness of this analysis can be improved by developing automated tools to process DEMs and provide locations for geomorphic indicators of concern.
