Research for New Water Table Management Systems
Water table management in the form of controlled-drainage and controlled-drainage/subirrigation is a feasible, yet under-utilized, practice in the Atlantic Coast flatwoods, the Ohio River...

Three-Dimensional Modeling of Transport of Fine Sediments and Contaminants in Lakes and Estuaries
The transport of fine sediments and contaminants due to currents and wind waves in estuaries and lakes have been studied by means of field experiment, laboratory experiment and a comprehensive...

A Modular Visual Interface for Computational Fluids Forecasting
A forecasting system is under development for predicting the three-dimensional physical features (e.g. velocity, temperature etc.) of large water bodies. Visualization and interface development...

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...

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...

Gropps Lake Dam
Gropps Lake Dam has a concrete ogee spillway with earthen abutments at either end of the spillway. The dam features an internal drainage system, outlet works, an energy dissipator, a steel...

Circulation Patterns Within the Near-Shore Region of the Southern Basin of Lake Michigan
The southwestern basin of Lake Michigan has been subject to extreme stresses because of its close proximity to large populations. A knowledge of the current patterns within this zone would...

Routing for Lake and Tidal Canal Drainage System
A routing method is presented for lake and tidal canal interconnected drainage system in coastal urban areas. Combing reservoir routing, channel routing, and discharge computation of the...

Fluid Mud Problems in Lakes, Reservoirs and Detention Ponds
An experimental study of wind induced surfacing of fluid mud bottoms in shallow water has been conducted. The experiments involved a channel placed within a wind tunnel, where a two-layered,...

Airborne Remote Sensing of Breaking Waves with Implications for Gas Exchange
It is shown that airborne remote sensing can potentially relate gas mixing effects within a temporally evolving breaking wave to relectivity changes, and can identify the intensity of...

Carbon Dioxide Pressure in Surface Waters of Canadian Lakes
Direct measurements of the partial pressure (pCO2) of carbon dioxide were made in lakes of three study areas: ELA (the Experimental Lakes Area) and...

Gas Transfer Velocities on Lakes Measured with Sulfur Hexafluoride
Gas transfer velocities have been determined on five lakes ranging in size from 0.13 km2 to 450 km2 using...

Hypolimnetic Aeration in Three Swiss Lakes
Eutrophication is quite common in low altitude Swiss lakes. Government agencies have set up phosphorus and oxygen limits for streams and lakes. Aeration equipment has been in use for up...

Experiment on the Efficiency of an Aspirator-Blower Type Aerator
An aspirator-blower type aerator was designed and tested successfully for small lake application. The experiment showed that significant amount of air flow can be generated by the aspirator...

Mercury Behavior in a Wastewater Sludge Incineration Process
The Western Lake Superior Sanitary District (WLSSD) in Duluth, Minnesota utilizes solid waste as fuel to incinerate wastewater treatment sludge, conserving energy resources while reducing...

Reef Breakwater Design for Lake Michigan Marina
An innovative breakwater concept consisting of a conventional breakwater and a submerged-reef breakwater operating in tandem has been designed for the southern end of Lake Michigan. The...

North Point Marina — A Case Study
North Point Marina is a full service, 1493 boat marina constructed by the State of Illinois on the shoreline of Lake Michigan to serve boaters from northeastern Illinois. Because of its...

Marina Flushing Along a Structurally Controlled Canal
Evaluation of flushing characteristics of a proposed marina located along a structurally controlled navigable canal is reported. This canal is operated to maintain the water level of Lake...

Racine's Reefpoint Marina and Festival Park—Sustaining Success Along the Lakefront
Racine County, Wisconsin, is a lakefront county os 173,000 residents located along the southwestern cost of Lake Michigan. A waterfront revitalization program, begun in 1982, has produced...
