Longshore and cross-shore morphological variability of a berm–bar system under low to moderate wave energy.The morphological variability of a berm–bar system is highly dependent on wave conditions with direct consequences for the evolution of the nearby coast; however, an … WebMar 1, 1988 · Cross-shore currents in surf-zone modelling. Coastal Eng., 12: 23-42. The paper discusses two aspects of the problem of incorporating the cross-shore circulation into mathematical-numerical nearshore models that also predict wave heights and set-up. One aspect is related to the proper choice of boundary conditions for the undertow, the other ...
