Porlock bay longshore drift
WebThe occurrence of a longshore drift in Whitsand Bay has been noted by Vincent and Osborne (1993), who estimated a drift speed of ∼0.1 m s −1 during their observations. The speed of the longshore drift depends on the square root of the root-mean-square breaker height and the wave angle at its break point (Komar, 1998).
