Abstract

• The generation and evolution of two-dimensional bores are analyzed numerically by using the Smoothed Particle Hydrodynamics (SPH) method. With this tool the bore steepening, breaking and post-breaking phases have been detailed investigated in the cases of constant and variable water depths. The bores were generated through a piston wavemaker moving with constant speed and the flow features have been studied by varying the water-depth Froude number from 0.5 to 0.95. The breaking of a plunging bore on the underlying water injects a cyclic process of splashes up with different strengths. The analysis highlighted also the occurrence of clockwise and anti-clockwise vortices, later pairing to form dipole structures. These affect the water evolution and can interact in a complex way with the free surface and with the sea floor. In the latter case, large stresses can be induced at the bottom that are responsible for instance for erosion. (literal)
