A new practical model for net sand transport induced by non-breaking waves and currents is being developed within the SANTOSS research project. Phase I of model development is reported here. In comparison with existing models, the main improvement is the description of the wave-related transport. More specifically, phase lag effects in the sheet-flow and ripple regime — which potentially have a large effect on the net transport — are accounted for in a parameterized way. The santoss model is calibrated against a large set of data from oscillatory flow tunnel experiments covering a wide range of flow and sand conditions. The new model is seen to perform better than existing practical transport models, and is applicable to a larger range of conditions.
