Part 4 presents an overview of how 1-dimensional and multidimensional modeling can be
applied to predict sediment transport and potential impacts associated with dam removal.
Part 4A (posted separately) shares a case study of the 1-D HEC-RAS model to the
removal of Simkins Dam on the Patapsco River, CT. Part 4B presents the use of GSMB to
evaluate sediment transport following Milltown Dam removal in Montana.
