Integration of 3D model THREETOX in JRODOS, implementation studies and modelling of Fukushima scenarios
(EDP Sciences, 2016)
The radionuclide transport model THREETOX was extended to include the multi-fractional sediments and two-step kinetics. The model was implemented into the decision support system JRODOS where forecasts of marine currents ...

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 ...

Modelling the mid-late Holocene evolution of the Huelva Estuary and its human colonization, South-Western Spain
(Elsevier, 2018)
The major changes that occurred in the southwestern estuaries of the Spanish Atlantic coast during the last 6500 yr BP were simultaneous to human settlement and therefore the understanding of their coastal evolution will ...

Floquet analysis of Kuznetsov-Ma breathers: A path towards spectral stability of rogue waves
(American Physical Society, 2017)
In the present work, we aim at taking a step towards the spectral stability analysis of Peregrine solitons, i.e., wave structures that are used to emulate extreme wave events. Given the space-time localized nature of ...

Assessment in marine environment for a hypothetic nuclear accident based on the database of tidal harmonic constants
(Elsevier, 2014)
The eleven nuclear power plants in operation, under construction and a well-planned plant in the east coast of China generally use seawater for reactor cooling. In this study, an oceanic dispersion assessment system based ...

The behaviour of I-129 released from nuclear fuel reprocessing factories in the North Atlantic Ocean and transport to the Arctic assessed from numerical modelling
(Elsevier, 2015)
A quantitative evaluation of the fate of 129I, released from the European reprocessing plants of Sellafield (UK) and La Hague (France), has been made by means of a Lagrangian dispersion model. Transport of radionuclides ...

U/Th dating of impure carbonates: 230Th/232Th activity ratios in detrital material
(Springer, 2019)
In environmental age dating the 230Th/232Th activity ratio is widely used as an indicator of detrital contamination. A clear relationship between this activity ratio and the carbonate sample’s age has previously been ...

A comparison of marine radionuclide dispersion models for the Baltic Sea in the frame of IAEA MODARIA program
(Elsevier, 2015)
Four radionuclide dispersion models have been applied to simulate the transport and distribution of 137Cs fallout from Chernobyl accident in the Baltic Sea. Models correspond to two categories: box models and hydrodynamic ...

Continuous families of solitary waves in non-symmetric complex potentials: A Melnikov theory approach
(Elsevier, 2019)
The existence of stationary solitary waves in symmetric and non-symmetric complex potentials is studied by means of Melnikov’s perturbation method. The latter provides analytical conditions for the existence of such waves ...

Numerical Modeling of the Releases of 90Sr from Fukushima to the Ocean: An Evaluation of the Source Term
(American Chemical Society, 2013)
A numerical model consisting of a 3D advection/diffusion equation, including uptake/release reactions between water and sediments described in a dynamic way, has been applied to simulate the marine releases of 90Sr from ...
