A modified non-linear cross-shore sediment transport relationship is developed based on equilibrium beach profile concepts and scaling. The proposed non-linear model called ‘CROSS’ is calibrated and compared with the commonly employed linear transport relationship using laboratory data. The results demonstrate that the non-linear transport model provides better overall predications than the linear transport equations. The CROSS model and three other commonly used models are applied to predict beach erosion at Ocean City, Maryland during the November 11, 1991 and January 4, 1992 storms. Overall, CROSS, EDUNE and SBEACH (version 3.0) provide reasonable predictions for both dune erosion and the entire profiles.
