Self-cleaning in an estuarine area formerly affected by 226Ra anthropogenic enhancements: numerical simulations
(Elsevier, 2005)
A numerical model of the Odiel–Tinto estuary (Spain) has been developed to study the self-cleaning process that was evidenced from 226Ra measurements in water and sediments collected in the period 1999–2002, after direct ...

A set of rapid-response models for pollutant dispersion assessments in southern Spain coastal waters
(Elsevier, 2010)
Three rapid-response Lagrangian particle-tracking dispersion models have been developed for southern Spain coastal waters. The three domains cover the Gulf of Cádiz (Atlantic Ocean), the Alborán Sea (Med iterranean), and ...

Modelling the environmental behaviour of pollutants in Algeciras Bay (south Spain)
(Elsevier, 2012)
An environmental study of Algeciras Bay is carried out through numerical modelling. First, a 2D barotrop ic model is applied to calculate tides and mean circulation. Results of this model are used by a sediment transport ...

Modelling of marine radionuclide dispersion in IAEA MODARIA program: Lessons learnt from the Baltic Sea and Fukushima scenarios
(Elsevier, 2016)
State-of-the art dispersion models were applied to simulate 137Cs dispersion from Chernobyl nuclear power plant disaster fallout in the Baltic Sea and from Fukushima Daiichi nuclear plant releases in the Pacific Ocean after ...

Marine radionuclide transport modelling: Recent developments, problems and challenges
(Elsevier, 2019)
A brief overview of the current status on the subject of numerical modelling of radionuclide transport in the marine environment is given: main transport processes occurring in the sea, basic approaches to solve such ...

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 ...

A modelling study on 137Cs and 239,240Pu behaviour in the Alborán Sea, western Mediterranean
(Elsevier, 2008)
A model for simulating the dispersion processes of 137Cs and 239,240Pu in the Alborán Sea is described. The model consists of two hydrodynamic models: a 2D depth-averaged model and a two-layer model which provide tidal and ...

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 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 ...

Modelling the transport of suspended particulate matter by the Rhone River plume (France). Implications for pollutant dispersion
(Elsevier, 2005)
A model to simulate the transport of suspended particulate matter by the Rhone River plume has been developed. The model solves the 3D hydrodynamic equations, including baroclinic terms and a 1-equation turbulence model, ...
