Abstract : This report is the second of a series of reports on experimental and working water quality enhancement techniques. The methods included in this report are limited to operational or structural modifications to prevent physical and chemical problems typically encountered in CE reservoirs. Descriptive information on hydraulic structure types and their functional and structural characteristics is given. Enhancement techniques discussed include guide curve changes, inflow routing, supplemental releases, concentration of flow through one gate, release strategy optimization, hypolimnetic withdrawal, pneumatic destratification, underwater dam, aeration-oxygenation systems, turbine venting, submerged skimming weir, multilevel selective withdrawal, and localized mixing. The problem that each technique is designed to address is discussed, along with the theory and methodology; referenced applications, a summary, and references are included.
