Journal Article
Tatlock, B., Briganti, R., Musumeci, R. E., & Brocchini, M. (2018). An assessment of the roller approach for wave breaking in a hybrid finite-volume finite-difference Boussinesq-type model for the surf-zone. Applied Ocean Research, 73, 160-178. https://doi.org/10.1016/j.apor.2018.01.012

This paper investigates the application of the roller approach for breaking waves in a 1D hybrid finite-volume finite-difference weakly-nonlinear Boussinesq-type model. The vorticity transport equation is employed to model the movement of vorticity t...

In this contribution we identify storm time-clustering in the Mediterranean Sea through a comprehensive analysis of the Allan Factor. This parameter is evaluated from long time series of wave height provided by oceanographic buoy measurements and hin... Read More about Time-clustering of wave storms in the Mediterranean Sea.

Advances in numerical modelling of swash zone dynamics (2016)
Journal Article

We present a comprehensive and critical review of work on the numerical modelling of swash zone processes between 2005 and 2015. A wide range of numerical models has been employed for the study of this region and, hence, only phase-resolving approach... Read More about Advances in numerical modelling of swash zone dynamics.

Intra-swash hydrodynamics and sediment flux for dambreak swash on coarse-grained beaches (2016)
Journal Article

The paper reports on dambreak-type swash experiments in which intra-swash hydrodynamics and sediment flux are measured for swash on a coarse sand beach and a gravel beach. Flow velocity and depth are measured using PIV and LIF respectively; the intra... Read More about Intra-swash hydrodynamics and sediment flux for dambreak swash on coarse-grained beaches.

In the present work, data for three single swash events are selected from those available for an accretive tide that occurred at Le Truc Vert beach (France) during a measurement field campaign at that location. These events are primarily chosen becau... Read More about Morphodynamical modelling of field-scale swash events.

Uncertainties in the physical modelling of the wave overtopping over a rubble mound breakwater: The role of the seeding number and of the test duration (2015)
