Analyzes the bar formation under breaking waves in a small-scale wave tank. Direction of sediment transport; Spatial and temporal variations of the wave height and the bathymetric profile.

A three dimensional hydrodynamic model including the suspended sediment transport is presented and applied to the microtidal coastal region off the Rhone river mouth. The dependence of the solution on turbulent parametization is first numerically investigated. The model is then adjusted and applied to typical climate events encountered duringa field campaign and an adequate agreement between numerical resultsand field measurements is obtained. Then, the suspended sediment transport is computed for climate conditions when relevant to the beach nourishment and shoreline evolution. [ABSTRACT FROM AUTHOR]

In this paper the WAM model is improved by considering the radiationstresses due to wave-current interactions in the spectral transport equation. The improved wave model is applied to compute wind waves inthe Rhone river mouth area in the Southern France under various steady and homogeneous wind conditions. The aim of this study is to determine the wave conditions involved in the long-term evolution of the shoreline. From the numerical computation results, we can conclude that even for obliquely offshore wind conditions, alongshore waves existin nearshore area and that the current due to the Rhone discharge has very little effect on the wave characteristics in relatively deep water.
