"The development of a model for the three-dimensional simulation of thermal discharges into rivers is essential because of the anticipated growth of power plants and the great amount of idealism of many of the alternative techniques for predicting temperature patterns. Based on the fundamental conservation equations for hydraulic flow and the model for the computer code COBRA, which is used in the prediction of flow and energy distribution in nuclear reactor coolant channels, a model is developed for use on digital computers.

To demonstrate the feasibility and capability of the model, two types of thermal discharges are simulated, lateral surface and single-port subsurface. Simulation of multi-port subsurface discharges is possible with this model but not demonstrated. The lateral surface discharge is compared with field data from the Philip Sporn Power Plant located on the Ohio River, and the single-port subsurface discharge is compared with published calculated data for the proposed Rush Island Power Plant located on the Mississippi River.

Results indicate that the method of determining the dispersion of heated effluent developed in this investigation is promising and has the possibility of being a universally suitable method for describing the temperature distribution from outfalls into rivers. However, further development is required to handle situations involving significant buoyant spreading and sizeable momentum jet discharges"--Abstract, page ii.
