A Mathematical Model of Blooms of Plankton Diatoms Blooms of plankton diatoms are of great importance for the management of drinking water reservoirs in the southern regions of the German Democratic Republic. A mathematical model has been developed by the author in order to find out optimal management alternatives. The model consists of coupled differential equations. The first step is a very simple model which is compared with a mass development of Asterionella formosa in the Saidenbach reservoir in the Erzgebirge. The dynamic properties of the improved model are examined with respect to the influence of various ecological parameters and that of initial values. It could be shown that loss rate and initial biomass of phytoplankton exert the greatest influence of bloom dynamics. In the last step, the results of the model are compared with a bloom ef Asterionella in laboratory cultures and with recent data obtained from the reservoir. A qualitative comparison between model behaviour and observations in the lake gives information about the validity range of the model parameters and provides ideas for further development. The applicability to water quality management of the model is considered.
