This dataset includes the model data used in the paper "The influence of swash-based reflection on surf zone hydrodynamics: a wave-by-wave approach", published in Coastal Engineering, vol. 122, pp. 27–43. It contains the raw model data from the A6-mono, A7-mono and A6-01 wave tests used in the paper (surface elevation, pressure and horizontal and vertical velocity). The OpenFOAM setup files needed to recreate every wave test from the paper are also provided.
