F LUME EXPERIMENTATION : EFFECT OF INFRA - GRAVITY WAVES ON THE OVER - WASHING Infra-gravity : one contribution to the dynamics of water level

I

Many low-frequency oscillations control changes in water level to the shoreline

I

infra-gravity (order of magnitude of 0.4 Hz) is known to control sand bar dynamics in the nearshore during storms

I

does infra-gravity strongly controls the water level to the shoreline during typhoons which are extreme events ?

N UMERICAL MODELLING : BRINGING THINGS TOGETHER

Smooth Particles Hydrodynamics (SPH) methods rely on the fact that both sediment and water are represented as PARTICLES. I

Objectives To build a SPH numerical experimental flume consistent with experimentation designed in the framework of KUNSHEN (THL)

I

To compare VOF (classical) and SPH approaches and to combine them to better understand hydro-morphodynamic processes over a natural/artificial sand barrier

I

To model (with SPH) the morphodynamic feed back of the barrier island to typhoon forcings
