Abstract
Publisher Summary A numerical model to simulate the dispersion of natural radionuclides in an estuary of southwest Spain is presented in this chapter. These radionuclides are released from a phosphate fertilizer processing complex. The dispersion of radionuclides in an estuarine system is studied. The chapter illustrates that, an ID model is used to study the general aspects of the movement of dissolved radionuclides in the estuary. Also, a 2D depth averaged model is applied to study, in detail, the dispersion of non conservative radionuclides in the area close to the release point from the complex. In addition, the transfers of radionuclides between the liquid and solid phases are described in terms of kinetic transfer coefficients. The model must solve, together with the equations whose solutions give the time evolution of specific activities in each of the four phases considered in the model, the hydrodynamic equations and the suspended matter equation, including the erosion and deposition terms. Further, it should be pointed out that these kinds of models are useful predictive tools that can be used in the assessment of contamination (radioactive, heavy metals, chemicals) following accidental or deliberate releases. Also, due to the predictive possibilities of the models, they can be applied for engineering purposes, to investigate, for instance, the effect of a potential dredging in the movement of contaminated sediment.
