Sand Bar Movement
An extended version of the numerical model introduced by Larson et al. (2013) to simulate long-term cross-shore material exchange for the subaqueous portion of the profile has been developed. Efforts have focused on improving the model to better account for beach systems consisting of two bars (inner and outer), as well as simulating the feeder response over time of nearshore dredged material bars, intended to function as beach nourishment. In this study, a description of the extended model and the results from the model component validation at two different sites in USA (Duck, N.C. and Cocoa Beach, Florida) are presented.
