Modeling and Control of Tailwater Quality Downstream of Reservoirs A Review

The objective of this paper is to identify and briefly summarize the state-of-the-art in controlling and modeling the tailwater quality downstream of hydraulic. structures. The approach will be to discuss the physical, chemical and the transport processes in the reservoirs. This will be followed by a discussion concerning the prototype observations of tailwater quality and a discussion identifying the methods and techniques for controlling the quality of tailwater. Ultimately, a tailwater quality model (TWQM), developed by Waterways Experiment Station, Corps of Engineers, Vicksburg, Mississippi, will be studied. This paper follows closely the Corps of Engineers experience as documented in their reports from the Waterways experiment Station, Vicksburg, Mississippi.
