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.

A two-way coupling methodology for wave propagation and wave-structure interaction with SPH is hereby presented. The methodology consists of combining a fast, fully non-linear wave propagation model, OceanWave3D, with an accurate Smoothed Particle Hydrodynamics (SPH) solver, DualSPHysics. At the coupling interface in the SPH zone, moving dynamic boundary particles are applied, which move according to the horizontal velocity calculated in the wave propagation model. The surface elevation is registered in the SPH zone and transferred back to the wave propagation model. Using this coupling methodology, a large domain can be simulated with the wave propagation model, with small, discrete SPH zones embedded to locally obtain higher accuracies. The communication between the solvers is implemented using OpenMPI. Three connected processes are run: OceanWave3D, DualSPHysics and Python. The latter is used to monitor the data transfer and manipulate the data in an efficient manner. The coupling methodology is validated by simulating wave propagation of linear and non-linear waves, and comparing the surface elevations and orbital velocities to a theoretical solution. Comparison with two experimental datasets is performed as well. The coupling methodology proofs that it is able to accurately propagate waves and shows a good agreement with theoretical and experimental results.
