【 摘 要 】

An algorithm is developed that is capable of calculating the formation of a tombolo in the lee of an offshore breakwater in a shoreline numerical model by inversely applying the method proposed in 1985 by Hanson and Kraus for constraining the shoreline not to retreat landward of a seawall. The algorithm is linked to a shoreline numerical model which uses curvilinear coordinates that follow the shoreline. The project of six segmented breakwaters at Chippokes State Park, Virginia is reported. The developed model is applied to the simulation of the shoreline change during the first nine months after construction of the Chippokes breakwaters.
