摘      要：This dissertation includes two parts. In part one, the standing wave motions and scours of sand bed in front of breakwaters by waves were investigated systematically. The wave surfaces and velocity field with an arbitrary bottom boundary were calculated based on the MAC method (Marker and Cell method). The scours in front of breakwaters under the action of standing waves, breaking waves and broken waves were investigated systematically based on experiments and theoretical analysis. Meanwhile, the sediment threshold was studied. In part two, a new concept consolidation force for the properties of consolidated silt was suggested in order to study the threshold and transportation, then, the erosions around an artificial island built on consolidated silt sea bed under the action of combined waves and currents were investigated by the Physical Model based on the principle of the Series Model method.
