Entrainment threshold of sand- to granule-sized sediments under waves

Artículo de publicación ISIAn improved method is presented to determine the threshold boundary velocity required to entrain sediments under waves, using the non-dimensional group settling velocity of sediments ranging from very fine sand to granules (0.1-33 mm), together with a dimensionless boundary velocity. In combination with a more accurate method to calculate the actual boundary velocity under linear as well as non-linear waves, this allows sediment entrainment to be predicted from deep water up to the breaker zone.CONICYT-FONDAP 1509001
