A One-Dimensional Model For Storm Breaching Of Barrier Islands, Cheol Shik Shin
Civil & Environmental Engineering Theses & Dissertations
A set of numerical models is developed for simulating the four stages of barrier breaching characterized by one horizontal spatial dimension.
The SBEACH model is employed for the first stage of dune/beach erosion. The Lax-Wendroff two-step explicit scheme for Stage II is developed to simulate initiation of ocean flood propagation on initially dry barrier islands and the method of characteristics (MOC), is employed to compute additional boundary data. The development of the Preissmann implicit scheme for water motion and a forward time centered space explicit scheme for sediment motion in Stages III and IV provide a tool to study the …
