Cascade Version 1: Theory and Model Formulation
Abstract
This technical note describes the physical processes background of the numerical model Cascade, Version 1, which simulates long-term, regional sediment transport and coastal evolution. Cascade can be applied to reaches of coast covering hundreds of kilometers at which morphologic evolution extending to centuries may be of interest. The setting may encompass several barrier islands separated by inlets at which sediment is transferred through tidal-shoal complexes and dredging. Cascade capabilities are demonstrated at two sites located on the United States east coast to illustrate typical applications. The first technical note in the Cascade series describes the Interface (Connell and Kraus 2006). Version 1 of Cascade mathematically describes longshore sediment processes, with cross-shore processes represented schematically. Research is underway to represent cross-shore processes at a basic level associated with, for example, storms and long-term forcing, such as wind and cliff erosion.
