Modelling the flux of radionuclides from the Rhone River into the Mediterranean Sea
(EDP Sciences, 2005)
A numerical model has been developed to simulate the input of radionuclides into the Mediterranean Sea through the Rhone River plume. The model is fully 3D. It solves the hydrodynamic equations, which include baroclinic ...

Measuring and modelling temporal trends of 226Ra in waters of a Spanish estuary affected by the phosphate industry
(Elsevier, 2005)
The presence and temporal evolution (1990–2001) of 226Ra in a tidal estuary affected by the phosphate industry has been investigated. Water samples collected in the course of four sep arate sampling campaigns were analysed ...

Modelling the suspended matter dynamics in a marine environment using a three dimensional σ coordinate model: application to the eastern Irish Sea
(Elsevier, 2002)
A numerical model to study the suspended matter dynamics in the sea has been developed. The model solves the three dimensional hydrodynamic equations, that are written in normalized σ coordinates so that vertical resolution ...

On the sensitivity of a marine dispersion model to parameters describing the transfers of radionuclides between the liquid and solid phases
(Elsevier, 2004)
The sensitivity of a marine dispersion model for non-conservative radionuclides, pre viously developed and validated for the English Channel, to parameters describing the exchanges between the liquid and solid phases ...

Demonstration of the stability or instability of multibreathers at low coupling
(2003)
Whereas there exists a mathematical proof for one-site breathers stability, and an unpublished one for two-site breathers, the methods for determining the stability properties of multibreathers rely on numerical computation ...

Inhomogeneous multiscale dynamics in harmonic lattices
(American Institute of Physics, 2005)
We use projection operators to address the coarse-grained multiscale problem in harmonic systems. Stochastic equations of motion for the coarse-grained variables with an inhomogeneous level of coarse graining in both time ...

Breathers in a system with helicity and dipole interaction
(American Physical Society, 2002)
Recent papers that have studied variants of the Peyrard-Bishop model for DNA, have taken into account the long range interaction due to the dipole moments of the hydrogen bonds between base pairs. In these models the ...

Testing the behaviour of different kinetic models for uptake/release of radionuclides between water and sediments when implemented in a marine dispersion model
(Elsevier, 2004)
Three kinetic models for adsorption/release of 137Cs between water and sediments have been tested when they are included in a previously validated dispersion model of the English Channel. Radionuclides are released to the ...

Neotectonics and shoreline history of the Rock of Gibraltar, southern Iberia
(Elsevier, 2004)
Several sets of staircased Quaternary marine deposits can be observed along the Gibraltar coast ranging from 1 to 210 m above the present mean sea level. Geomorphological mapping establishes, from the relationship between ...

Modelling the dispersion of radionuclides by a river plume: Application to the Rhone river
(Elsevier, 2005)
A numerical model to simulate the transport of radionuclides in a river plume has been developed. The model solves the hydrodynamic equations, including baroclinic terms and a 1-equation turbulence model, suspended ...
