Abstract
The effect of the model for promoting surface layer flow, which was proposed in Part 8 of the study, when warm water is discharged into the main flow from a rectangular conduit in a side wall of channel is discussed. Calculations are made with the model to simulate the behaviour of warm water flowing into an open channel in the authors' laboratory and into a natural river. The Tennessee River in the United States is chosen as an example of a natural river because temperature distribution data measured downstream of the Widows Creek power plant by the Tennessee Valley Authority in 1967 is avairable. The computed results show that the model is effective for open channels or natural rivers where warm water is discharged transversely from the main flow. Information on the water surface temperature is necessary when the model is applied. Water surface temperature prediction methods are based on a bimodal model are also shown.
