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 relevant benefits of hyperspectral sensors for water column determination and seabed features mapping compared to multispectral data, especially in coastal areas, have been demonstrated in recent studies. In this study, we used hyperspectral satellite data in the accurate mapping of the bathymetry and the composition of water habitats for inlan...

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...

... To give an order of magnitude, averages calculated from 2010 to 2020 indicate that all sluice gates are closed for about 147 days (40% of the year), up to two sluice gates are opened about 101 days (28%), and at least three sluice gates are opened for about 117 days (32%). A previous study measured the ''sea to lagoons'' daily average volume at about 39,000 m 3 day , and the ''lagoons to sea'' daily average volume at about 48,000 m 3 day for the 1999-2007 period (Boutron et al., 2021). A permanently opened gate is located west on the channel near the 13 sluice gates (Fig. 2) and give access to a fish pass, which was implemented in January 2004. ...
... We note that other optical methods are used for bathymetry, such as reported in Refs. [14,15], with some advantages but cannot compete with the depth resolution of time-of-flight ranging. ...
... The impact of wind is rarely considered when describing the multiple and complex mechanisms driving the morphodynamics of intermittent estuaries, even though wind can have a considerable influence on the internal lagoon morphology [42,43]. This is especially important in shallow basins where wind forcing can produce surges of significant amplitude [44][45][46][47][48]. These surges can be comparable in magnitude to the effects produced by river discharges and could thus potentially contribute to controlling an intermittent estuary if the surge is directed toward the barrier. ...
