A computer model is developed to rapidly simulate dissolved oxygen content in the Cuyahoga River under varying conditions of flow and biochemical oxygen demand. It is composed of three separate models: Model I is based upon Streeter-Phelps equations (Streeter and Phelps, 1925); Model II is a revised and expanded version of the Delaware Estuary finite difference model (Thomann, 1972); and Model III is a time-variant model. These models, which have been used to simulate present and projected dissolved oxygen levels for the entire length of the Cuyahoga River, show that the municipal and industrial treatment programs to be implemented by 1978 will result in improved dissolved oxygen conditions in the Cuyahoga River. However, run-off and benthic oxygen demand will still result in a severe oxygen sag in the navigation channel during summer low flows.
