Environmental and Hydraulic Considerations in the Design of a Circulating Water Cooling System
Environmental considerations play an important part in the design of a condenser cooling system. A once-through system may require assessment of a combination of events to determine the...
Verification of a Three-Dimensional Numerical Hydrodynamic Model of the C&D Canal and Adjacent Estuaries
A 3D hydrodynamic model of the C&D Canal and adjacent estuaries was developed by using the WES-CH3D code. CH3D uses a simplified second order vertical turbulence model based on...
Model Study of an Intake Structure
To increase the delivery capacity of an existing gravity-feed water supply pipeline in Orange County, California, modification of the existing structure and placement of a booster pumping...
Physical Model of a Floating Trash Boom to Control Aquatic Weeds at the TVA Widows Creek Fossil Plant
The Tennessee Valley Authority (TVA) Widows Creek Fossil Plant seasonally encounters adverse accumulations of aquatic weeds at the intakes of the condenser cooling water pumps. To reduce...
Application of a 2-D Water Quality Model (BETTER) to Manage Effects of Low Flow and Wastewater Effluents in Cheatham Lake, Tennessee
Applications of BETTER, a 2-D reservoir water quality model, have been made by the Nashville District Corps of Engineers (Corps) and by the Nashville Metropolitan Water and Sewerage Services...
Tracking Cold Water in a Large Reservoir System
The Tennessee Valley Authority (TVA) Environmental River Resource Aid (TERRA) is a computer workstation graphics display that tracks environmental variables in the power service area....
Reviewing the Operating Objectives of the TVA Reservoir System
Under the Tennessee Valley Authority's Lake Improvement Plan, approved by the Board of Directors in February 1991, minimum flows will be provided systemwide, the releases...
Visualization of a 3D Model of Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic and water quality model (WQM) of the Chesapeake Bay and its major tributaries has been developed by the US Army Engineer Waterways Experiment...
Scientific Visualization Techniques Applied to Water Quality and Transport
Applying the advanced-computer technology available at the San Diego Supercomputer Center (SDSC), researchers from SDSC and the U.S. Geological Survey (USGS) simulated and visualized numerical...
Dam Removal Methods, Elwha River, Washington
Preparation of an Environmental Impact Statement (FERC, 1991) for licence applications for the Elwha and Glines Canyon hydroelectric projects on the Elwha River, Washington, included evaluation...
Sediment Modeling of Dam Removal Alternatives, Elwha River, Washington
The new version of the U.S. Army Corps of Engineers (ACOE) 1-Dimensional sediment transport model, HEC-6 'Scour and Deposition in Rivers and Reservoirs', was...
Sediment Problems Associated with Dam Removal, Muskegon River, Michigan
This paper presents an analysis of sediment movement in Michigan's Muskegon River following the removal of Newaygo Dam. The analysis utilized a physical process simulation...
Predicted Fluvial Response to Dam Removal in the Kalamazoo River Valley, Michigan
Research has been conducted by the Michigan Department of Natural Resources (MDNR) to predict the fluvial response to dam drawdown and determine the distribution of recent deposits along...
Proposed Methodology to Update Embayment Sedimentation Data for TVA Reservoirs
The purpose of this paper is to evaluate the accuracy and usefulness of bathymetric data resulting from routine fisheries and aquatic biology hydroacoustic surveys in TVA reservoirs for...
Enhancing Effluent Water Quality of Sedimentation Basins Using Constructed Wetlands Technology
The Tennessee Valley Authority (TVA) has constructed twelve wetlands to treat acid drainage at reclaimed coal mines and fossil-fueled power plants. These wetlands are designed primarily...
Large Woody Debris Effects on Channel Friction Factor
A simple method for quantifying large woody debris (LWD) density and computing associated friction factors was developed and tested using data from the South Fork Obion River in western...
Ultrasonic Velocity Meter Used in Stream Gaging
Many streams and canals in Florida are affected by tides or control structures and experience very low flow velocities at times. For example, the St. Johns River in northeastern Florida...
Model Study of a Hurricane Surge Barrier Gate Valve
Physical model studies were conducted to determine the hydraulic performance of a unique vertical butterfly-gated structure. These studies were also used to determine the torque on the...
Model Studies of Outlet and Intake at McCook Reservoir
Two separate physical models were used to investigate the outflow and inflow into the proposed McCook Reservoir. The proposed reservoir will be located in McCook, Illinois, and will serve...
McClure Park: A Multi-Purpose Off-Stream Storage Facility for Tulsa, Oklahoma
The City of Tulsa is in the process of implementing a flood control plan for the 61 square-mile (158 km2) Mingo Creek watershed. The federally-assisted...
