In this work we explore the extension of the quasi-optimal sparse grids method proposed in our previous work \On the optimal polynomial ap- proximation of stochastic PDEs by Galerkin and Collocation methods" to a Darcy problem where the permeability is mod ...
Chlorinated ethenes (CEs) represent a major environmental concern in most industrialized countries. These compounds, used as solvents and degreasing agents since the 1940s, have been released accidentally into the environment. Being recalcitrant to aerobic ...
A numerical study was conducted to investigate the influence of tides on the fate of terrestrially-derived BTEX discharging through an unconfined aquifer to coastal waters. Previous studies have revealed that tide-induced seawater circulations create an ac ...
Intertidal wetlands are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on three-dimensional, variably satur ...
Intertidal wetlands such as salt marshes are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on 3D, variably ...
A contaminated alluvial aquifer, in a former gasworks factory and discharging to an adjacent river, was the object of field and laboratory investigations to assess pollutant attenuation and dispersion. Various organic and inorganic compounds were found in ...
Groundwater managers have often to face regional degradation of the quality of the groundwater under the pressure of diffuse pollution. One of the most problematic and widespread contaminant is certainly nitrate whose concentrations are found in many aquif ...
Marine and freshwater ecosystems are fundamentally different regarding many biotic and abiotic parameters. The physiological adaptations required for an organism to pass the salinity barrier are considerable. Many eukaryotic lineages are restricted to eith ...

Modeling groundwater flow and contaminant transport in industrialized and urbanized alluvial plains is challenging because of the dynamic nature of the strongly interacting river – groundwater system and the scarcity of data. An original combined regional ...
