Summary

A correct understanding of the complex morphodynamic phenomena in lagoons and in coastal basins is particularly important for the management of waterways, ports and natural environments. Some of the most important tools available to develop an understanding are numerical models. In this paper, in order to develop a 2DH depth averaged model suited to describe coastal basins, a one-dimensional depth-averaged sediment transport model is presented and tested. In particular, two benchmarking tests, able to describe typical lagoon situations, are discussed: migration of a trench in steady flow and migration of a trench in steady flow with waves parallel to the current. In order to evaluate the best fit for the experimental data, different wave-current shear stress models are tested and compared.
