|Extended model description=Shoreline is a "line model" for modeling the evolution of a coastline as the result of wind/wave-driven longshore sediment transport. It is based on conservation of mass and a semi-empirical sediment transport formula known as the CERC formula. This model was specifically adapted for modeling the evolution of the coastline near Barrow, Alaska. | |Extended model description=Shoreline is a "line model" for modeling the evolution of a coastline as the result of wind/wave-driven longshore sediment transport.

|Describe available test data sets=Model was only used for modeling coastline change in the vicinity of Barrow, Alaska. Hourly wind data from a met station at the Barrow Airport was used to drive the model. High-resolution coastline data digitized from aerial photos by Manley et al.
