A modeling study of Ra-226 dispersion in an estuarine system in south-west Spain
(Elsevier, 1994)
A numerical model to study 226Ra dispersion in the Odiel River, in which two fertilizer plants release their wastes, has been developed. The hydrodynamic equations have been solved to obtain the instantaneous water state ...

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 ...

Three-dimensional modelling of the tide-induced dispersion of radionuclides in the sea
(Elsevier, 1998)
A three-dimensional marine dispersion model for radionuclides has been developed. ¹he model solves the three-dimensional hydrodynamic equations and, simultaneously, the three-dimensional advective—diffusive dispersion ...

Soil to plant transfer of 226 Ra in a marsh area: Modelling application
(Elsevier, 1998)
¹he Odiel river forms an estuarine system which surrounds a large marsh area. A phosphate fertilizer processing complex releases its wastes into the estuary. ¹he presence of 226Ra in soils and plants (Spartina Densiflora) ...

Uranium and thorium concentrations in an estuary affected by phosphate fertilizer processing: Experimental results and a modelling study
(Elsevier, 1997)
The Odiel river, in southwest Spain, forms an estuarine system which is affected by waste disposal from a fertilizer complex. Uranium and thorium concentrations in waters and suspended matter, activity ratios and distribution ...

U- and Th-isotopes in an estuarine system in southwest Spain: Tidal and seasonal variations
(Elsevier, 1996)
The presence of U- and Th-isotopes in suspended matter from an estuarine system which surrounds a phosphate fertilizer processing complex has been investigated. A clear radioactive impact from the complex has been confirmed ...

Distribution of natural radionuclides in sequentially extracted fractions of sediments from a marsh area in Southwest Spain: U isotopes
(Elsevier, 1999)
A study of the distribution of U in different fractions of intertidal sediments collected in a marsh area enhanced by the radioactive wastes discharged from a fertilizer complex has been carried out. The study has shown ...

A numerical model to simulate the tidal dispersion of radionuclides in the English Channel
(Elsevier, 1999)
A numerical model to simulate the tide-induced dispersion of conservative radionuclides in the English Channel has been developed. The model solves the shallow-water hydrodynamic equations and, simultaneously, the advection ...

Kinetic transfer coefficients for radionuclides in estuarine waters: Reference values from133Ba and effects of salinity and suspended load concentration
(Springer, 1998)
In estuarine environments there are important spatial and temporal changes in both salt and suspended load concentrations. An experimental procedure have been developed to produce kinetic parameters being representative ...
