Nearshore ocean processes feature strong non-linear
interactions of tides, winds, high-frequent surface waves,
and river discharges. For example, the sedimentation,
sediment resuspension, and morphological changes of the
seabed in shallow water are directly controlled by the
interaction of currents and waves through radiation stress
and bottom boundary layer dynamics (Longuet-Higgins
and Stewart, 1960; Longuet-Higgins 1970a, b; Grant and
Medsen, 1979). Because the interaction is highly nonlinear
and significantly varies in space and time, it is imperative
that we develop a fully coupled hydrodynamics-
wave-sediment model to understand this complex system.
