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 ...

The Zanclean megaflood of the Mediterranean – Searching for independent evidence
(Elsevier, 2020)
About six million years ago, the Mediterranean Sea underwent a period of isolation from the ocean and widespread salt deposition known as the Messinian Salinity Crisis (MSC), allegedly leading to a kilometer-scale level ...

Three-dimensional modelling of the tidal dispersion of non-conservative radionuclides in the marine environment. Application to 239,240 Pu dispersion in the eastern Irish Sea
(Elsevier, 1999)
A three-dimensional model to simulate the tidal dispersion of non-conservative radionuclides in a marine environment has been developed. The model solves the three-dimensional hydrodynamic equations using normalized s ...

Modelling the dispersion of non-conservative radionuclides in tidal waters .2. Application to Ra-226 dispersion in an estuarine system
(Elsevier, 1996)
The Odiel river is an estuary system located in the south-west of Spain and affected by tidal dynamics. A phosphate fertilizer processing plant releases part of its wastes directly into the Odiel river. The model described ...

Wave Propagation in Periodic Metallic Structures with Equilateral Triangular Holes
(MDPI, 2020)
This paper studies wave propagation in a periodic parallel-plate waveguide with equilateral triangular holes. A mode-matching method is implemented to analyze the dispersion diagram of the structure possessing glide and ...

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 ...

210Pb distribution in riverwaters and sediments near phosphate fertilizer factories
(Elsevier, 1996)
two fertilizer factories operate at the estuary formed by the Odiel and Tinto rivers in Southwestern Spain. In previous work the authors have shown that such operation enhances the natural radionuclide background of the ...

Study of forward and backward modes in double-sided dielectric-filled corrugated waveguides
(MDPI, 2021)
This work studies the propagation characteristics of a rectangular waveguide with aligned/ misaligned double-sided dielectric-filled metallic corrugations. Two modes are found to propagate in the proposed double-sided ...
