Summary

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.

Purpose

A seamless elevation dataset provides the opportunity for a variety of modeling efforts that traverse the aquatic/non-aquatic transition areas. Examples of such modeling include physical models that route river flow at various discharges, and biological models that predict species occurrence for species that utilize the transitional areas (e.g., emergent vegetation). The merging of the bathymetry and lidar also assured the best interpolation in near-shore aquatic areas that often lacked bathymetry data due to shallow conditions during surveys.
