Analysis of Cross-Shore Movement of Natural Longshore Bars and Material Placed toCreate Longshore Bars

摘要

This study develops empirical predictive expressions for design of nearshoreberms formed of dredged material. Such berms are placed in the form of long linear sand bars and are expected to behave as natural bars. The study examines the cross-shore movement of natural longshore bars at Duck, North Carolina. Beach profile survey data are available at approximately 2-week intervals from 1981 to 1989, together with measurements of the wave conditions. Two bars are typically
