Abstract
    This report aims to determine the effect of the Sinterklaas storm during the 5th and 6th of December 2013 on the beach and shoreface hydrodynamics and morphology along the coast of Oostende, and specifically the beach at Mariakerke where a monitoring program is currently ongoing in the framework of the ARGONAUTS project (ARGus and in-situ mONitoring of beAch and shoreface NoUrishmenT for Sustainable coastal safety). Atmospheric and marine conditions, and also in-situ hydrodynamic measurements are reported. A comparison of the beach and shoreface morphology before and after the storm is quantified to evaluate the impact of the storm. Further morphological investigations on the shoreface are carried out by modeling its changes during the storm. Based on the derived analysis, we find that the morphological impact of the storm was less relevant as expected before the storm and, in fact, was comparable to the effect of a typical winter storm in this area.
