Available in PDF, EPUB and Kindle. Book excerpt: Methods of aerating hydropower releases were reviewed based upon information from both published and unpublished sources. Techniques which aerated water as it passed through turbines and aeration techniques which were used in the reservoir itself to improve dissolved oxygen concentrations in the releases were the focal points of this review. Both American and European installations were investigated.

This book was released on 1987 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes various in-lake, in-structure, and downstream techniques to enhance the dissolved oxygen concentration of hydropower releases. In-lake and in-structure techniques appear to be the most applicable for Corps of Engineers projects because of the large discharges of most hydropower projects. Of these, the in-structure techniques, particularly turbine venting, appear very attractive considering cost and degree of improvement. Tests were conducted at the Clarks Hill Dam powerhouse to evaluate various aspects of turbine venting and thereby provide a data base to develop predictive and design capabilities for turbine venting systems. Test results indicated that, at most, the oxygen deficit in the penstock could be reduced by about 30%, i.e., if the penstock oxygen deficit is 8.0 mg/(l), then, at most, about 2.4 mg/l of oxygen could be absorbed into the release flow. Two reaeration processes that contributed to the overall oxygen transfer were observed: (a) due to the turbulence in the tailrace area and (b) due to the air bubbles (vented through the turbine) as they traveled through the draft tube. A numerical computer model was developed that included the impact of the changes in thermodynamic (pressure) state as the bubbles passed through the draft tube. By developing the 'pressure time history', the increased potential for oxygen transfer due to the increase in hydrostatic pressure was included in model formulation. Good agreement was obtained in comparing model predictions and oxygen uptake data from previous tests at Clarks Hill.

Available in PDF, EPUB and Kindle. Book excerpt: Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.
