UMRR Dresden Reach Topobathy Separate data for floodplain elevation and bathymetry were collected on the Upper Mississippi River System (UMRS) by the US Army Corps of Engineers (USACE), Upper Mississippi River Restoration (UMRR) Program. While many information needs can be met by using these data separately, in many cases seamless elevation data across the river and its floodplain are needed. This seamless elevation surface was generated by merging lidar (i.e., floodplain elevation) and bathymetry data. Merging the data required special processing in the areas of transition between the two sources of data.

Small areas containing priority mussel habitat had additional collection efforts to map water velocities and bottom composition. Combining these data in a GIS can provide key components to characterizing physical benthic habitat for native mussels in a riverine environment. These information needs were highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution.

Backscatter is the acoustic reflectivity, which is the measure of energy obtained from the echo intensity, and can provide an indication about the nature of the river bottom and its physical character. Image analysis and classification of backscatter, with the combined datasets of bathymetry (and its derivatives) and ground truthing, can predict surficial substrate, or sediment type. For habitat analysis, these datasets were desired by the NPS to help inform and mitigate...
