The Vaccarès Lagoon System, located in the central part of the Rhône Delta (France), is a complex shallow coastal lagoon, exposed to a typical Mediterranean climate and a specific hydrological regime affected by man-controlled exchanges with the sea and agricultural drainage channels. In this article, we report the results obtained by a series of m...

The present paper is specifically focused on enclosed or semi-enclosed basins where the wind is the dominant driver of water surface tilting, leading to the so-called wind tide contributing to water levels rise. Wind-induced free surface tilting is studied using the 1-D steady form of the depth-averaged shallow water (Saint-Venant) momentum equatio...
Chapter
This lecture aims to give an overview of water waves and their propagation in inhomogeneous media. Effects of varying bathymetries, varying currents, or structures including porous media are then considered. After some generalities on water waves, governing equations for regular plane waves for the study of wave scattering including reflection, ref...
Article
Wave scattering over a sinusoidal bottom in the presence of a vertically sheared current is investigated experimentally and compared with a modified-mild slope model taking into account a linear vertical shear. Waves were generated in a flume without or with an opposing sheared current and propagated over a patch of 10 sinusoidal bars before dissip...

The aim of the study is to understand the wind effect on mean water level variation in semi-enclosed shallow basins. The studied physical phenomenon is nearly steady water surface tilting due to wind stress, the so-called wind tide (Platzman (1963)). During strong wind conditions, wind tides can have significant consequences on low-lying areas such...

Rivers solid discharge represents a substantial environmental issue, especially for the coastal marine environment. Unlike continental climate rivers, Mediterranean rivers show large discharge variability linked to rainfall, runoff and groundwater discharge, and can be temporary dry. Solid yields are difficult to predict due to variable source of f...

Extended mild-slope models (MMSs) are examined for predicting the characteristics of normally incident waves propagating over sinusoidal bottom topography in the presence of opposing shearing currents. It is shown that MMSs are able to provide quite good predictions in the case of Bragg scattering of waves over rippled bathymetry without a current,...

Sloshing tests are performed on a rectangular tank filled with bottom-mounted vertical cylinders. The cylinders, in regular staggered arrangements, are first emergent then shortened to be fully submerged. Different porosities are achieved by varying the number of cylinders. The tank undergoes forced horizontal motion at frequencies around the natur...

Propagation of water waves in coastal zones is mainly affected by the influence of currents and bathymetry variations. Models describing wave propagation in coastal zones are often based on the numerical solution of the Mild Slope equation (Kirby, 1984). In this work, an extension of this equation is derived, taking into account the linear variatio...

Chapter
An experimental study was carried in the Ocean Engineering Basin (BGO FIRST), as part of GIS HYDRO in 2008. The results allowed us to note an important rise in the wave amplitude unexpected by the mild slope equation. In addition we note the presence of a vertical shearing in the current which seems to influence significantly the dynamics of water...

As a general rule, it is accepted the glicade hemoglobine level as a good index in the DM control. No doubts about the DM diagnostic with HbA1c > 6,5%, but difficult to confirm the diagnostic with HbA1c < 6,5%.For a correct treatment in DM-2, we must consider life style changes, changing several feeding habits and promoting phisycal exercise. For a...

Since the first moment insuline was administered in a patient in 1922, different long-lasting types of insuline have been developed, something that let us use different treatment management strategies when antidiabetic oral drugs have failured in DM-2. Bearing in mind the glitazones as the less appropiate drug to be used with insuline therapy, the...

At the moment we have three different consensus from three different Scientific Societies with guidelines for insulinization. According to the SED (Spanish Diabetes Society), with HbA1c between 6,5–8,5%, it is recommended to beguin with life style changes + metformine and when not enough add a second oral drug or insuline. With HbA1c > 8,5% it is r...
