Tidal circulation, sediment and pollutant transport in Cádiz Bay (SW Spain): A modelling study
(Elsevier, 2013)
A numerical model to simulate the dispersion of particle-reactive tracers in Cádiz Bay (SW Spain) has been developed. It includes a hydrodynamic submodel to provide water currents, a sediment transport submodel, which ...

Testing models for predicting the behaviour of radionuclides in aquatic systems
(Elsevier, 2008)
The paper describes the main results of the international EMRAS model testing exercise for radionuclide transport in watershed-river and estuarine systems. The exercises included the following scenarios: multi-point ...

Assessment of state-of-the-art models for predicting the remobilisation of radionuclides following the flooding of heavily contaminated areas: the case of Pripyat River floodplain
(Elsevier, 2006)
The performances of models are assessed to predict the wash-off of radionuclides from contaminated flooded areas. This process should be accounted for in the proper management of the aftermath of a nuclear accident. The ...

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 ...

Modelling the tidal dispersion of 137 Cs and 239,240 Pu in the English Channel
(Elsevier, 2000)
A numerical model to simulate the tidal dispersion of non-conservative radionuclides in the English Channel has been developed. The model solves the shallow water hydrodynamic equations and, simultaneously, the suspended ...

Kinetic box models for the uptake of radionuclides and heavy metals by suspended particulate matter: equivalence between models and its implications
(Elsevier, 2008)
In recent years an increasing experimental effort has been paid to the study of the sorption process of radionuclides and heavy metals by particulate matter in aquatic environments. This has led to the development of ...

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 ...

A particle-tracking method for simulating the dispersion of non-conservative radionuclides in coastal waters
(Elsevier, 2002)
A particle-tracking method has been used to simulate the dispersion of non-conservative radionuclides in the sea. Three dimensional turbulent diffusion and the interactions between water, suspended matter and bottom sediments ...

Some considerations on the dependence to numerical schemes of Lagrangian radionuclide transport models for the aquatic environment
(Elsevier, 2023-05)
Lagrangian models present several advantages over Eulerian models to simulate the transport of radionuclides in the aquatic environment in emergency situations. A radionuclide release is simulated as a number of particles ...

The cumulative effect of three decades of phosphogypsum amendments in reclaimed marsh soils from SW Spain: 226Ra, 238U and Cd contents in soils and tomato fruit
(Elsevier, 2008)
Phosphogypsum (PG), a by-product of the phosphate fertiliser industries, has been applied as soil amendment to reduce Na saturation in soils, as in the reclaimed marsh area from SW Spain, where available PG has a typical ...
