Title: Simulation of Regional Longshore Sediment Transport and Coastal Evolution - The 'Cascade' Model
Abstract: Abstract : A numerical model called Cascade is introduced for simulating regional sediment transport and coastal evolution. Cascade can be applied to stretches of coastline covering hundreds of kilometers where evolution extending to centuries may be of interest. A typical setting encompasses several barrier islands separated by inlets at which sediment is transferred through tidal-shoal complexes. Complex regional trends in shoreline orientation can be represented, as well as sediment sources and sinks, such as beach nourishment, cliff erosion, wind-blown sand, and dredging. Processes are modeled at the local and regional scale, and the interaction between the scales is described in a cascading manner from regional to local. Main components of the model are described, followed by an application to the south shore of Long Island, New York, where the regional sediment transport pattern was simulated, including opening of two inlets and the response of the adjacent shore.
