Abstract

Linear transition ripples were observed in 3-m water depth in fine-grained sands on an unbarred beach during both the onset and decay of a storm event. The measurements were made using scanning acoustic systems and a laser-illuminated video bed profiling system. The transition ripples were characterized by low steepness, and stable geometry over O(1-h) time scales under moderate grain roughness Shields parameter conditions. Both onshore and offshore migration were observed, at rates which correlate well with the local hydrodynamic forcing.
