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.

目标：长期目标是预测移动海底对组合波流强迫的动态调整。该提案的重点是底部应力以及非线性波-波和波-流相互作用在调整过程中的作用。主要目标是提高对以下方面的认识和理解： (1) 波浪能、近床流体湍流、底部应力和床态发生之间的关系； (2)垂直泥沙通量平衡和泥沙夹带； (3)高阶速度矩在水平泥沙通量中的作用； (4) 床型的发生、生长、迁移和腐烂。
