【 摘 要 】

A new non-linear cross-shore sediment transport model called CROSS is developed based on equilibrium beach profile concepts and scaling relationships. CROSS and three other existing models, CCCL (Chiu and Dean 1984), EDUNE (Kriebel 1989) and two versions of SBEACH (version 2.0, Larson and Kraus 1989, and version 3.0, undocumented) are investigated by comparing erosion occurring from November 1991 to January 1992, at Ocean City, Maryland, the site of a major beach fill placed by the State of Maryland and Federal Government in 1988, 1990 and 1991. Among the four models, CCCL is the only one which overpredicts average dune erosion; the other three underpredict it. Overall CROSS and EDUNE yield better predictions than the other two models.
