A basic framework for the elaboration of a model of the dynamics of phosphorus in Cuban coastal ecosystems is presented. We start from a zero-dimensional model, which includes several physical, chemical, and biological processes depending only on time. In this, first a relatively isolated ecosystem was considered, and then polluting loads from runoff were included. Then, the vertical space variable was introduced, given the importance of the interaction of phosphorus with the bottom in many coastal ecosystems. This resulted in a one-dimensional model of predominantly thermo-hydrodynamic model, coupled with a model of radiative transfer in atmosphere and ocean. The thermo-hydrodynamic frame of the model consists of a system of three partial differential equations whose solutions were found and turned out to be well behaved from a mathematical point of view. A preliminary application to a case study was done and analyzed. They were able to lay the foundations for the preparation of a Cuban hydrodynamic model. |
