Abstract

A consolidated cohesive sediment layer exists below a layer of sand on some beaches along the Great Lakes (glacial till) and the Gulf of Mexico. The erosion process of consolidated cohesive sediment may be gradual but irreversible (no recovery) apart from sand and gravel released from the eroded consolidated cohesive sediment. The cohesive sediment erosion rate is increased by a thin mobile layer of sand and decreased by a thick sand layer. The complicated interactions of waves, sand and cohesive bottom are simplified and incorporated into an existing cross-shore numerical model.
