Equilibrium characteristics of sand beaches in the offshore zone

摘要: Abstract : A theoretical and experimental inves igation of equilibrium profiles a i orting th offs ore zone s d beaches is described. The investigation was designed to test the applicability existing idealized theories prediction characteristics laboratory sand beaches. Two different sediment motion criteria are considered; first, in which moments on stationary particle equilibrium, called incipient second, oscill g h o t mo io establis motion. e p ri ent l uipment consisted 100 foot long, glass-walled wave tank containing bulkhead-type av mac nd n tal be c (Au or)
