+In this paper, we study such an event. On February 28, 2017, a 50T concrete block was dropped by a wave on the crest of the
 Artha breakwater. Luckily, the event was captured by a photographer, and a wave buoy located 1.2km offshore captured
 the seastate. Information from the photographer allowed to establish the approximate time at which the block
 displacement occured. The goal of this paper is to model the hydrodynamic conditions near the breakwater that lead to
 the displacement of the 50T concrete block.

+Several approaches can be used when modelling flow near a breakwater. Depth-averaged models can be used to study the
+transformation of waves on complex bottoms. Studying the hydrodynamic conditions under the surface can be achieved
+using smoothed-particles hydrodynamics (SPH) or volume of fluid (VOF) models. SPH models rely on a Lagrangian
+representation of the fluid, while VOF models rely on an Eulerian representation. VOF models are generally more mature
+for the study of multiphase incompressible flows.
 
-Testing kalliope
+In this paper, we use two nested models: a large scale one-dimensionnal model to study the transformation of the wave
+from the wave buoy to the proximity of the breakwater, and a VOF model in two vertical dimensions to study the
+hydrodynamic conditions near the breakwater. The large scale model uses a depth-averaged non-linear non-hydrostatic
+model that was already calibrated by \textcite{poncet2022}. The nested model is a VOF model based on volume averaged
+Reynolds averaged Navier-Stokes (VARANS) equations and a macroscopic representation of the porous armour of the
+breakwater. The model is qualitatively calibrated using photographs from the storm of February 28, 2017.
