摘要：

Modelling the dispersion of non-conservative radionuclides in a given marine environment involves a wide set of complex processes: horizontal water movements (advection and diffusion), suspended matter dynamics, sediment composition, accumulation or erosion rates, continental water input and its dispersion pattern, evaporation-precipitation balance and the ionic exchange among the different phases. In this paper we present the conceptual and computational basis of a mathematical model which includes all the above processes. This model has been developed in different stages, in such a way that every new step includes the previously validated model and is subject to a further validation. Here, the sub-grid scale processes, such as the ionic exchanges and other activity transfers among phases, are included In the second part of this work, which is presented in a separate paper, the model is applied and validated using studies of Cs-137 and Pu-239+240 dispersion in the Irish Sea.
