Evaluation of Embankment Erosion at TVA's Chickamauga Project
Studies were made to evaluate the extent of erosion to be expected under probable maximum flood (PMF) conditions. The erosion studies were made using the EMBANK computer program. The results...
Overview of Autoventing Turbine Technology Development Project
Low concentrations of dissolved oxygen (DO) in the discharge of hydro plants represent one of the most significant environmental concerns confronting the hydropower industry. This is especially...
Experimental Difficulties Encountered in Testing Air/Water Mixtures
The Tennessee Valley Authority and Voith Hydro, Inc., are conducting a joint research project to study the effects of air admission on hydraulic turbines. Francis turbine models, homologous...
Application of Appropriate Technology in Hydroelectric Project Rehabilitation
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. A primary concern is spillway and stability inadequacies resulting...
Appropriate Technology in Infrastructure Development and Management
Infrastructure management principles apply to appropriate technologies used for hydraulic structures. However, some of the principles are more culturally sensitive than others, mainly...
A Review of Modeling and Analysis Approaches for Optimization of Reservoir System Operations
Numerous mathematical models have been developed for sizing reservoir storage capacities and establishing operating policies during project planning, for reevaluating the operating policies...
Seawater Delivery for Use in Aquaculture Development
Seawater is used extensively in industrial and aquacultural developments world wide, and aquaculture in particular requires large quantities of seawater. Development and design of facilities...
