Abstract : The Inlet Geomorphology Evolution work unit of the CIRP develops methods and provides geomorphic perspective on federal navigation and coastal projects. It connects existing databases, models, traditional and remote sensing measurements, and USACE projects to create valuable guidance that address geomorphic questions. The present focus of the work unit is a common alternative considered for placement of sediment dredged from navigation channels, in the form of mounds or shore-linear features in the nearshore area adjacent to inlets. However, there is little guidance available for design and anticipated temporal and spatial scales of evolution of these nearshore placements. In addition, for mixed-sized dredged material including fine-grained sediment, 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 activities include application of the Coastal Modeling System (CMS) to long-term evolution of inlets and the development of the Sediment Analysis GeoApp (SAGA) tool.
