heal.abstract	Computational modeling aspects of weak plunging wave breaking, over a relatively mild sloping laboratory beach, were investigated in the present paper. Comparisons against latest elaborate experimental data were used to support the discussion. Smoothed Particle Hydrodynamics method was implemented as a numerical tool and the recently enhanced version of the academic 'open source' code SPHysics v.2 was ratified. Fine spatial resolution calibration was undertaken in an attempt to render effective a Sub-Particle Scale Smagorinsky-type turbulence closure that treats energy dissipation of eddy formations for the unresolved flow scales. Fine visual reproduction of the ragged freesurface flow deformation was supplemented with plausible results concerning classic wave dynamics characteristics, sophisticated turbulent surf-zone features and wave-induced currents.
