Abstract

With the help of a transport model, the issues of the distribution of neutrally floating particles simulating microplastic (MP) in Lake Baikal are studied. A three-dimensional model of the lake hydro-thermodynamics in the non-hydrostatic formulation is used to produce the fields of currents and the other necessary parameters for the transport model. To give generality to the conclusions, we use a set of parameters that are conditionally combined into hypothetical scenarios. In them, we design the "climatic" scenarios of external influences, in accordance to which the fields of currents and temperature in the hydrodynamic model are calculated. Depending of the goals of the study, we also formulate the specific tasks for giving the impurity sources in the transport model. The results of calculations are presented, in which some possible locations of an increased concentration of impurities in the lake were revealed.
