Abstract : The Inlet Geomorphology Evolution work unit of the CIRP evaluates federal navigation and coastal projects over time scales much greater than dredging cycles, planning timelines, and the dimensions of the navigation channel. The present focus of the work unit is directed towards developing guidance for placement of sediment in the nearshore, which is a common alternative considered for placement of dredged sand and mixed sediments in the nearshore area adjacent to inlets. However, there is little guidance available for design and anticipated temporal and spatial scales of evolution. In addition, there are environmental concerns about transport and burial of fines over sensitive submerged aquatic habitat areas. Present primary activities are directed towards addressing these nearshore placement challenges. Additional activates address application of the Coastal Modeling System to long-term evolution at inlets and the development of a sediment sampling database.
