Objectives: The long-term objective is to predict the dynamic adjustment of the mobile seabed to combined wave-current forcing. The focus of this proposal is the role of bottom stress, and non-linear wave-wave and wave-current interactions, in the adjustment process. Primary objectives are improved knowledge and understanding of: (1) the relationships between wave energy, near-bed fluid turbulence, bottom stress and bed state occurrence; (2) the vertical sediment flux balance and sediment entrainment; (3) the role of higher-order velocity moments in the horizontal sediment flux; and (4) bedform genesis, growth, migration and decay.

目的：长期目标是预测移动海床的动态调整，以相结合的波电流强迫。该建议的重点是底部应力的作用，以及在调整过程中的非线性波浪波和波流相互作用。主要目标是改善知识和理解：（1）波能，近床流体湍流，底部压力和床状态的发生之间的关系； （2）垂直沉积物通量平衡和沉积物夹带； （3）高阶速度力矩在水平沉积物通量中的作用； （4）床形的起源，生长，迁移和衰减。
