Mathematical Modeling of Plankton Biomass Dynamics During the Spring Thermal Bar in Kamloops Lake

The mathematical model developed for simulating hydrobiological processes in a lake takes into account the diurnal variability of the heat fluxes and wind stress on the water surface. Study of the interaction of the biological components is accomplished by using the nutrient–phytoplankton–zooplankton–detritus model of Parker. The results of numerical modeling of plankton biomass dynamics during the development of the spring riverine thermal bar in Kamloops Lake, British Columbia, Canada, influence on phytoplankton concentrations in the upper layers of the lake. At the presence of wind stress, zooplankton populations increase by transport from the river mouth, but concentrations of phytoplankton reduce due to the supply of colder watersfrom the open lake
