Reservoir Reevaluation in TVA
Demands for the use of dams and reservoirs tend to change after the projects are completed. The Tennessee Valley Authority (TVA) works with State and local groups to try to increase the...
Estimating Earthquake Hazard of Municipal Water Systems
This paper uses the City of Memphis as a case study to present the seismic hazard evaluation of a municipal water delivery system. The horizontal peak bedrock accelerations resulting from...
Predicting Effects of Global Climate Change on Reservoir Water Quality and Fish Habitat
This paper demonstrates the use of general circulation models (GCMs) for assessing global climate change effects on reservoir water quality and illustrates that general conclusions about...
Benefits from Floodplain Management Activities in Relation to Operating South Holston Dam
Floodplain management activities have primarily been directed toward avoiding floodplain siting where practical; where siting is unavoidable, elevating structures, facilities, or equipment...
Oil Spill Impacts on Aquifers
This study attempts to evaluate the seismic hazards along a forty inch pipeline and the impact of a pipeline rupture in the recharge area of the aquifer serving most of West Tennessee....
Utility of a GIS in Watershed Management?A Case Study
A geographic information system data base was established for a small watershed in Shelby County, Tennessee, for both surface and subsurface water attributes. The surface water portion...
Modeling Erosion and Effects of Agricultural BMP's on a West Tennessee Watershed
The application of Hydrological Simulation Program FORTRAN (HSPF) to nonpoint source data was examined. The model is used to determine the effects of land management practices upon surface...
Radon Entry & Control Versus Indoor Dynamics
The measurements of air infiltration, interzonal transport and exfiltration as the diagnostic procedures have been significantly influential in the selection, implementation and evaluation...
Flood Impact and Management of Levees in Tennessee
The construction of private levees is causing flooding and erosion problems along several tributary rivers in West Tennessee. The severity of these problems is recognized by the State...
Drought in Tennessee: Implications on Irrigation System Capacity
Recent droughts in Tennessee have led to a study of the required irrigation system capacity for the state. Data from 1951 through 1988 were analyzed for probabilities of precipitation...
Implementing a Groundwater Control Board
Memphis, Tennessee, situated on the banks of the Mississippi river, has never utilized this vast resource for water supply. Instead, Artesian wells have supplied the Memphis, Tennessee...
Computer Support for TVA's Reservoir System Operations: Hardware
The current computer systems in use at TVA for hydrologic data collection and modeling are approaching ten years old. A study is in progress to determine the computer systems needed to...
Computer Support For TVA's Reservoir System Operations: Software
In the early 1980's, the Tennessee Valley Authority implemented its Water Resources Management Information (WATREMAIN) system to provide support for operation of its integrated multipurpose...
TVA Weekly Scheduling Model Application Experience
Development of TVA's Weekly Scheduling Model was completed in 1980. Eight years of experience covering a wide variety of applications has now been accumulated. Since the basic...
Water Quality Management During Low-Flow Periods: A Systems Analysis Approach
Water quality objectives may require water managers to consider deviations from original project purposes to provide downstream water quality maintenance during low-flow periods. The decision...
Meeting Environmental Commitments at Power Plants Using Real-Time Reservoir Scheduling
This paper describes two different real-time modeling systems that determine if scheduled hydro releases will affect meeting environmental commitments. The modeling system for John Sevier...
TVA: A Half-Century of Sedimentation Experience
The Tennessee Valley Authority (TVA) is a regional resource development agency, created by the United States Congress in 1933 and charged with bringing to the Tennessee River watershed...
Routing a Cold Water Release Through TVA Reservoirs to Control Intake Temperatures at a Power Plant
A volume of cold water was routed some 160 miles through the TVA reservoir system to keep a nuclear plant intake temperature within safety limits. Mathematical modeling of the operation...
Comparison of Tenn-V and TR-55 on TVA Watersheds
The storm hydrograph simulation models TENN-V and TR-55 were compared as to their respective abilities to reproduce 468 storms observed on 54 watersheds. TR-55 did not represent the Tennessee...
Extreme Flood Probability Estimates in Practice
Selecting the safety design flood for a dam or siting structures where flooding would cause severe social or economic disruption requires balancing the likelihood and consequences of failure...
