Abstract : The compilation of papers presented herein represents the formal contributions of participants in the workshop on phytoplankton-reservoir interactions. The formal papers include an introduction describing the purpose and scope of the Waterways Experiment Station Environmental and Water Quality Operational Studies (EWQOS) research program, followed by technical papers. The first paper, by Bierman, provides a review of processes and formulations related to nutrient kinetics with emphasis on the comparison between fixed and variable stoichiometry models. The next paper, by Goldman, reviews current knowledge and practice related to the effects of temperature on phytoplankton behavior. The third paper, by Lehman, provides a discussion of current and suggested approaches to modeling zooplankton-phytoplankton interactions. The relative importance of mass transport as compared to kinetic factors using both theoretical concepts and field data is discussed by Di Toro. Megard discusses the importance of light and its relation to mixed depth in controlling algal production. A review of current models and approaches to combining the various ecological processes is provided by Park and Collins. A paper by Scavia then provides some important perspectives on the use and interpretation of model results. Particular attention is given to transfer rates between state variables. The remaining papers provide background on reservoir behavior and use of bioassay techniques.
