Abstract: The US Army Corps of Engineers (USACE), Mississippi River Geomorphology and Potamology (MRG&P) Program, addresses the need for the USACE to have access to the most up-to-date and technically competent scientific data and analysis for providing navigation and flood risk management in an environmentally responsible manner (USACE MVD 2020). MRG&P seeks to better understand river behavior by studying existing and historical data. This is accomplished by collecting and studying numerous sources of data including in situ gauge and sediment data, ecological and geomorphological data, and in the case of this technical note, a Geographic Information System-produced Digital Elevation Model (DEM). A DEM can interchangably be called a Digital Terrain Model, but it will be referred to as a DEM in this publication. The DEM is composed of a grid of pixels spaced at regular intervals, with the pixel value representing elevation at that point (Bilskie and Hagen 2013). Hydrologic modeling of rivers is common practice throughout the world, and the Mississippi River is no exception. There are at least three distinct models for which this project provides topographic and bathymetric data.
