Abstract:

This US Army Corps of Engineers USACE Regional Sediment Management technical note RSM-TN describes an RSM effort that converted a one-dimensional 1D sediment transport model of the Chippewa River confluence with the Mississippi River into a two-dimensional 2D model. This work leveraged recent sediment data collection and tested the new 2D sediment transport capabilities in the Hydrologic Engineering Center, River Analysis System HEC-RAS Version 6.0. In addition to the benefits of software testing, the resulting model developed through this effort can provide more accurate spatial and temporal information about sedimentation in the Mississippi River navigation channel and help inform future dredging strategies for the St. Paul District, USACE.
