Full textThe purpose of this Ph-D work aims to enhance knowledge and better describe wave propagationthrough porous media in order to propose a new characterization of coastal defense structures. The influenceof the specific surface parameter (fluid-solid contact surface) of porous media is then highlighted at givenporosity for steady and oscillatory wave induced flows with experiment series carried out in either wave tankor basin. Experimental data are compared with theoretical models based on wave potential theory numericalsolved by use of integral matching method at the domains’ boundaries.Wave scattering in the presence of porous structure is studied in both 2D and 3D cases. Interference processwithin the porous media are observed in the 2D case, leading to an oscillatory behavior of the reflection versusfrequency. Additional interference processes are observed in the transverse direction in the 3D case, leadingto a wave behavior strongly dependent on wave dynamics at both sides of the porous structure for resonantcases. Either linear or quadratic behavior of the dissipation is observed within the porous media. The role ofthe specific surface in the dissipation process is demonstrated. Both flow regimes and scale effects are alsodiscussed

Full textL'objectif de ce travail est d'étudier expérimentalement et numériquement la propagation et le déferlement
d'ondes de gravité.
La première partie, expérimentale, propose des méthodes de calcul, basées sur les houles de Stokes, pour la mesure d'ondes partiellement stationnaires à partir d'instruments de type électromagnétique (S4) ou
acoustique (ADV) donnant des mesures synchrones de vitesses et/ou de pression. Les influences du courant,
de la direction de propagation, de la profondeur d'immersion des appareils ainsi que des effets non
linéaires sont alors étudiés à partir de données en bassin et in situ.
La deuxième partie, numérique, consiste en la validation d'une méthode de suivi de surface libre de type
SL-VOF (Semi-Lagrangian Volume Of Fluid), insérée dans un code de calcul industriel (code EOLE de la
société Principia R&D). L'onde de gravité est modélisée par un soliton. L'étude de la propagation et du
déferlement du soliton est effectuée pour deux applications : sur une marche (discontinuité du fond) puis sur un fond de pente constante 1/15. L'évolution de la surface libre, son élévation et le champ de vitesses
sont alors comparés aux résultats expérimentaux.

Full textThis PhD thesis focuses on a specific part of the interactions between waves, current and bathymetry: the influence of the vorticity on the Bragg resonance phenomenon. Two numerical models, based on hyperbolic equations, are compared: the Mild Slope equation and the Modified Mild Slope equation, both extended to consider vorticity. To establish some trends about the wave behaviour in such configuration, the influence of the vorticity has been compared to the influence of the surface current velocity, in a parametric study. To go further, an experimental campaign has been settled in a wave flume, and the reflexion of regular waves propagating above sinusoïdal bathymetry and horizontally varying sheared currend has been registered for a large range ofwaves frequencies. Sorne strong conclusions asserted themselves: under the influence of a varying sheared current, the maximum of reflexion is reduced, both in amplitude and frequency, but another local maximum appears in higher waves frequencies (between 1.25 and l .45Hz). Moreover, our modelling achieved to represent the amplitude of the Bragg Peak quite well, but always overestimated the associated frequency. Thanks to a strong questioning of the theory and a collaboration between several researchers, a new modelling arised, with an original decomposition of the velocity potential taking into account the asymmetry between the incident and reflected wavenumbers. The first results are very optimistic: find the Bragg Peak frequency is not a problem anymore, and the study on the vorticity influence can continue. This new approach in coastal engineering will generate as many questions as opportunities

Full textThis PhD study aims to analyze the free surface within a wave channel by using a new optical measurement. This process uses a video and a laser induced fluorescence to visualize the water movement within a wave channel equipped with glass walls. The good contrast between the water and the air obtained on the captured images allows to detect accurately the free surface. A pixel range can give one punctual evolution of the free surface like a traditional punctual measurement of the free surface (for example: resistive probe). So the space resolution of the free surface can be obtained with a very high resolution. This optical measurement opens an in-depth investigation on the decomposition of incident and reflected harmonic waves using four wave gauges proposed by Lin et al. (2004). On the one side, it confirms the good pertinence of this method with the fundamental waves. On the other side, some difficulties appear about the estimation of higher harmonic waves. The same conclusions are found by comparing the four fixed gauges method of Lin et al. (2004) with the moving probes method of Brossard et al. (2000). This new measurement method allows to characterize the different behaviours of the free surface nearby a sloping marine structure according to the structure inclinations. For this purpose, various parameters associated with the extreme forms of the free surface are analyzed in relation to the structure inclination

Full textFor the design of marine or coastal structures subject to nonlinear waves in deep to shallow water, it is crucial to take into account both wave/structure and wave/wave interactions on large fluid domains. In this purpose, a high-order Boussinesq-type model has been developed and used to investigate nonlinear wave interactions with piecewise rectangular bottom-mounted (surface piercing) structures. Several practical applications of the model involving highly nonlinear wave run-up on a rigid plate are presented. Both normal and oblique wave conditions are considered. A new physical phenomenon creating large wave amplification in front of reflective structures is also fully studied

Full textThe two-dimensional (horizontal plane) models of free surface wave propagation are deduced from the fundamental equations of fluid mechanics. They are based on the non Iinear non-dispersive wave approach described by Saint-Venant equations (hydrostatic pressure), and on the non-linear dispersive wave approach described by Serre and Boussinesq type equations (non-hydrostatic pressure). The Boussinesq and Serre equations are developed using perturbation method with definition of the domain of validity of various approximations. A considerable number of Serre and Boussinesq type models is due to the choice of the kind of horizontal velocity, for which we give unambiguous interpretation. Higher-order terms introduced by Madsen to improve frequency dispersion serve as a base of "product" of different Boussinesq-type modeis. A one-dimensional and a two-dimensional (in plane) finite elements model of Serre and Boussinesq-type equations with improved frequency dispersion are presented. The time discretisation is based on Lax-Wendrofftype non-diffusive scheme. The one-dimensional numerical models are validated comparing with theoretical solutions and results obtained experimentally for horizontal and uneven bottom with various boundary conditions. The two-dimensional (in plane) Serre-Boussinesq finite elements models, capable to predict the refraction, diffraction and reflection are validated with good agreements between numerical and experimental results. The irregular meshs for complex bathymetry are created using I-DEAS code. A new one-dimensional breaking wave propagation model based on the Boussinesq type equations is developed by introduction of turbulent dissipation. Satisfactory agreements between numerical results and experiences are obtained

Full textIn this work we focused on the electromagnetic wave scattering by a controlled swell. The microwave signal backscattered by a controlled swell in a wave basin is studied both theoretically and experimentally. The electromagnetic response of such a surface depends on its shape, its dielectric characteristics, and antennas characteristics and positions. Measurements acquired with a monostatic microwave scatterometer installed above a wave basin, in which regular and irregular waves are generated, are compared with simulation results obtained from two electromagnetic models, based on the Physical Optics approximation (PO) and the Method of Moments (MoM). The swells studied by the electromagnetic simulator are given by the paddle movement simulation. From both methods, a good agreement is observed between the results. Also, a good agreement is observed between theoretical and experimental results around the inclination angle 0°. Nevertheless, a difference is observed between results for highest angles. This is due to the propagation of short ripples on top of the desired long waves. Those ripples are generated both by the gaps existing between the wavemaker paddles and by the beach located at the end of the wave tank, where waves break in order to avoid reflection. These short ripples are modeled and added to an example of a regular surface. For regular surfaces with additional ripples, better agreement is then observed between the results
