Interfacing with the Public on Water-Related Issues—What TVA is Doing
Management of the water resources of the Tennessee River Basin has been a primary responsibility of the Tennessee Valley Authority (TVA) since its creation almost 60 years ago. In the...
Applying the ARMOS and MOFAT Models to a Major Oil Spill
A study was undertaken to evaluate the impact of a crude oil pipeline rupture in the recharge area of the aquifer serving most of West Tennessee. The main challenge was to model the volume...
Operation of the Tennessee Valley Authority Water Control System Under Extreme Drought Conditions
The Tennessee Valley region recently suffered through the most severe drought of record. As increasing demands were placed on the reservoir system, operating priorities were modified to...
Seismic Mitigation of the Memphis Water System
Memphis, Tennessee is located in zone 2 of the 1988 Standard Building Code, close to the New Madrid Seismic Zone. The probability of having a seismic event of significant magnitude is...
A GIS Based Synthetic Watershed Sediment Routing Model
For most watersheds, extensive water quality data are not available. Land use, topographic, edaphic and meteorological information is generally available; but without extensive water quality...
Facing the 21st Century with an Aging Hydro System
The Tennesse Valley Authority (TVA) has implemented a comprehensive study of their hydroelectric plants in order to extend their service life for the next 50 years into the 21st century....
Current Status of Wetland Protection and Management in Tennessee
In order to save the remaining wetland resources and to manage these wetlands to the benefit of all, the State of Tennessee currently is in the process of formulating a comprehensive state...

Evaluation of the FASTCHEM Model for Predicting Leachate Attenuation at Fossil Power Plants
The Tennessee Valley Authority (TVA) has applied the model FASTCHEM to identify retardation mechanisms and predict solute transport at two fossil power plants. FASTCHEM (acronym for fly...
Hatchie River and Schoharie Creek Bridge Failures
Within a 2-year period two large bridges collapsed into flooded rivers resulting in a total of 18 people plunging to their deaths. Both bridges had been inspected by probing, but had not...
Model Tests for the Evaluation of Auto-Venting Hydroturbines
The most significant environmental problem for many hydroelectric facilities is the water quality of turbine discharges. The primary water quality problem is often low dissolved oxygen...
Energy Losses Due to Air Admission in Hydroturbines
Admission of air at the exit of a hydroturbine runner is an attractive technique for raising dissolved oxygen levels downstream of a hydro plant. The air admission, however, is generally...
Numerical Modeling of Air/Water Mixtures for Internal Flows
The Tennessee Valley Authority (TVA) currently is working with several organizations to develop design tools for the aerating hydroturbine. Part of this effort includes the investigation...
Efficiency and Cavitation Effects of Hydroturbine Venting
Volkart and Bohac et al. have summarized much of the past work on aeration of hydroturbine releases to improve downstream water quality. Conventional alternatives for increasing dissolved...
Physical Model of a Floating Trash Boom to Control Aquatic Weeds at the TVA Widows Creek Fossil Plant
