Abstract

This paper presents mathematical model of expansion of bacterial pollution discharged by submarine outfall. Initial dilution is calculated using parametric models. Results of the model of initial dilution such as value of initial dilution and characteristics of the polluted plume were used as input data for 2-D model of secondary dilution. Model of secondary dilution consists of two submodels: the flow field model and the model of transport and transformation of bacterial pollution. Mathematical base for the flow field model is equation of potential flow. Mathematical base for the model of transport and transformation of bacterial pollution is 2-D form of the equation of convection and diffusion with adequately adapted boundary conditions. Equations are solved numerically usin
