In 2012 verloren we Jean Jacques Peters, voormalig ingenieur van het Waterbouwkundig Laboratorium (1964 tot 1979) en internationaal expert in sedimenttransport, rivierhydraulica en -morfologie. Als eerbetoon aan hem hebben we potamology (http://www.potamology.com/) gecreëerd, een virtueel gedenkarchief dat als doel heeft om zijn manier van denken en morfologische aanpak van rivierproblemen in de wereld in stand te houden en te verspreiden.
Het merendeel van z’n werk hebben we toegankelijk gemaakt via onderstaande zoekinterface.

An accurate prediction of wave overtopping over the crest of coastal structures and wave-induced loading is essential to guarantee coastal safety. Due to the presence of a very shallow foreshore at the Belgian coast, this is not straightforward. Within the CREST project, a numerical model is being developed to accurately predict these wave interactions with structures on a very shallow foreshore. Sediment transport in front of the structure as well as the wave structure interactions are simulated with the open-source CFD software OpenFOAM. Wave propagation over the beach until the wave breaking point is modelled with SWASH, a model based on the non-linear shallow water equations in order to limit the computational cost. A one-way coupling methodology between these two models is proposed. The capability of OpenFOAM as stand-alone model to accurately predict wave loading forces on buildings for a case with a very shallow foreshore is demonstrated by comparing the numerical results to experimental data. The ability of OpenFOAM to simulate scour processes is validated by experimental data of a submerged jet flow over an apron. Furthermore, a first test case with the coupled OpenFOAM-SWASH model presenting the propagation of regular waves is described.
