IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
In coastal and estuarine areas, waves and tidal currents always coexist, which has great influence on sediment
transport. Ití»s of great significance to research the numerical simulation of sediment movement under co-action of tidal
currents and waves for harbor development, reclamation, coast utilization etc. State-of-the-art of the sediment transport
simulation under co-action of waves and currents is reviewed. First, the hydrodynamic simulation is briefly reviewed,
which is mainly about simulation of currents movement effected by waves and wave modelling affected by currents.
Then, some key problems in sediment transport modelling are focused on, which are sediment incipient motion,
cohesive and non-cohesive sediment simulation, equilibrium and non-equilibrium sediment transport simulation, the
source/sink term, the diffusion coefficient, bottom boundary conditions, as well as some issues in 1DV, 2DH and 3D
version, etc. In addition, the modelling strategies for wave-current-sediment interaction are briefly presented. In the end,
discussion and further development approach are proposed.
