The dispersion of heated effluents in three spatial coordinates was studied. Detailed results are described in a series of publications of which the report provides a summary. Results include a state-of-the-art review of temperature dependencies for various water quality parameters, a description of techniques used in the development of momentum and energy transport models, a coupling of the energy equation with mass balance equations for biochemical oxygen demand and dissolved oxygen, the verification of relationships in an experimental flume, and the development of a new momentum transport model.
