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.

The DEMs have a 10-cm resolution (Boom site is 0.5-m) to provide ultra-high-resolution elevations for investigating the use of hydroacoustic technologies for quantifying habitat for imperiled mussels Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) typically associated with rock structures (e.g., wing dams, revetment) in rivers. Bathymetry is essential for providing the depths and shapes of underwater terrain and it represents the three-dimensional features (or relief) of underwater terrain.

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. This information is highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution.

Multibeam echosounders collect multibeam and sidescan simultaneously, providing high-resolution images of the riverbed. Sidescan images, in raster format, show the recorded intensity of acoustic signal returns from the riverbed. The acoustic data were collected from the East Pit of the Hanson Pits (where accessible) of the Marseilles reach June 27, 2018, and August 25, 2020.

Park biologists are interested to learn how forest loss in the late 2000s and early 2010s caused by beech bark disease (BBD) is affecting these wildlife species. Biologists need to know where forest canopy gaps exist and identify where the greatest canopy connectivity loss has occurred prior to research observing and collecting data on wildlife species. This data set will show biologists where canopy gaps existed shortly after BBD infection occurred at PIRO, as derived using object-based image analysis and National Agriculture Imagery Program...

Sidescan sonar emits conical or fan-shaped beam down across a wide angle perpendicular to the path of the sensor through the water. The intensity of the acoustic reflections from the riverbed is recorded in a series of cross-track slices and when stitched together in a mosaic, form an image of the riverbed giving the user a view of the material and texture of the riverbed. Sidescan mosaics are being used in this project mainly as ancillary information to help view the rock structures and will also be used for investigating the use of hydroacoustic technologies for quantifying habitat for imperiled...
