Dans cet exposé préliminaire, nous confronterons dans l’ordre ci-dessus, les faits avec les théories en cours, nous en indiquerons. quelque points faible et le améliorations ou compléments que nous entendons y apporter comme constituant le but de cette étude. Nous préciserons et justifierons le choix de méthodes de calcul et d'approximation...

Holthuijsen, L.H. (author)
The methods used in practice for computing wave-propagation are mainly based on two theories. The first one describes the refraction of waves in case of variable depth. The determination of this effect is based on the assumption that a wave locally behaves as a straight-crested wave of constant amplitude. Because of this the celerity is...

The geometry of the seabottom may cause waves to refract such that a concentration of wave-energy occurs. In view of the particular shape and dimensions of the Dogger Bank, it was interesting to find out whether such a phenomenon may occur in this area. It is expected that only longer waves will show the effect mentioned (periods of about 12 s)....

Radder, A.V. (author)
In this report,a description is given of some approximation methods, to solve the problem of short wave propagation in shoaling water. The problem is stated as an elliptic initial value problem, which is in general not properly posed. After reduction of the wave equation to the Helmholtz equation, the transition to amplitude and phase is...

Two reports prepared under order of Rijkswaterstaat on combined refraction and diffraction problems,notably with irregular waves. The research is subdivided into the following parts, which will be reported separately: I) linear irregular wave propagation over an uneven bottom; 2) non-linear regular wave-propagation over an uneven bottom; 3) non-...

Van Nieuwenhuijze, D.O. (author)
This study has been undertaken in order to find out what is to be understood by " rather gentle " slopes. That is, it is an inquiry into the limits of applicability of the refraction - diffraction equation. In this study, the refraction - diffraction equation, as well as the set of equations from which it has "been derived, are used to predict...

Booij, N. (author)
A mathematical model for the combined refraction-diffraction of linear periodic gravity waves on water is developed, in which the influence of inhomogeneities of depth and current is taken into account. The model is used to compute partial reflection of waves a gully or an undersea slope, with influence of a current. The model is also applied to...

The numerical wave model CREON is developed to predict the propagation and transformation of wave properties in shallow water. In Gao et al. (1993), which is referred to as Part I in the following, a description is given of the theoretical and numerical treatment of the model. In the present report, we present various computational results. The...

The CROSMOR-model (Van Rijn, 1997, 1998), representing wave propagation, refraction, shoaling, breaking, associated sand transport and morphology in cross-shore direction based on a probabilistic approach, has been applied to simulate the hydrodynamics and the nearshore bar behaviour for three experiments in the large-scale Delta flume o f Delft...

We developed and demonstrate an analysis method in which we calibrate the intensity scale of cross-sectional transmission electron microscopy (TEM) using Cu K? reflectometry. This results in quantitative in-depth density profiles of multilayer structures. Only three free parameters are needed to obtain the calibrated profiles, corresponding to...

The paper aims to investigate the refraction phenomena of shock waves at ferrum-beryllium (Fe-Be) interface. The equations of state of Fe and Be adopt “stiffen gas” formula. For the regular refraction, the shock polar theory is employed. The critical angles of transition of the regular to irregular refraction about the different shock intensity...

A novel crystallization technology, Eutectic Freeze Crystallization (EFC) has been investigated and further developed in this thesis work. EFC operates around the eutectic temperature and composition of aqueous solutions and can be used for recovery of (valuable) dissolved salts (and/or or acids) and water from a wide variety of aqueous process...

We present a stochastic model for the evolution of random ocean surface waves in coastal waters with complex seafloor topography. First, we derive a deterministic coupled-mode model based on a forward scattering approximation of the nonlinear mild slope equation; this model describes the evolution of random, directionally spread waves over fully...

Compare the 1D spectrum computed in SWAN (Svasek, 2007) with it measured by buoy OS4 in the Oosterschelde Estuary, serious underestimation of wave energy can be found on low-frequency band. Investigation has been performed to find the possible reasons for the missing energy on low frequency part. In this study, diffraction is hypothesized as the...

Mode-dependent shifts of resonant frequencies of cavities in liquid crystal (LC) infiltrated planar photonic crystals (PhC) are experimentally observed when the temperature is varied across the LC ordering transition. The shifts can be in opposite directions, even for two very similar nearly degenerate modes. The behavior is attributed to the...

During the fall of 2003, an extensive measurement campaign called the “Nearshore Canyon Experiment” (NCEX) was set up along the coast of La Jolla, California. The project site covered an area in which two submarine canyons are located, respectively La Jolla and Scripps Submarine Canyon. Over 20 institutions collaborated on recording the...
