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