Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Automated Data Collection for Reservoir Regulation
Various regulation changes in the Lake Winnebago basin have been proposed regarding the protection of wetlands and assurance of adequate outflows for water quality. To implement these...
Models for Lake and River Basin Analysis
This tutorial describes basic concepts, purposes and issues of mathematical models for lakes and river basins. Simulation and optimization models are discussed and their structure and...
Optimal Operation of a System of Lakes for Quality and Quantity
A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints....
Modeling of Reservoir Operations for Managing Ecological Interests
A network simulation model is applied to a three reservoir system to analyze the effects of alternative operating policies in response to such seasonal water demands as hydropower, pollution...
Great Lakes Water Diversion: Legal Issues
This article deals with state/provincial, regional, federal and international legal issues involved with protecting Great Lakes water. First, the article describes the institutions and...
Multi-Objective Planning: Great Lakes Water Policy Issues
This paper reports upon the development of computer algorithms for multi-objective planning for Great Lakes water policy issues. Sample applications are presented for the control of phosphorus...
Optimization of Flood Control Projects
Project optimization analysis techniques have become indispensable tools for the design, management, and administration of flood control improvements. The increasing complexity of engineering...
Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...
Predicting Lake-Chain Quality with Augmentation
Steady-state mass-balance models of lake phosphorus are analyzed with regard to predicting augmentation (or dilution) effects. One form of these models employs a retention coefficient...
Town Lake: An Environmental Impact Assessment
The City of Dallas, Texas, had little experience with environmental impact assessments of major capital improvements projects. Yet when deciding whether to build a 110,000,000 urban lake,...
Estimating Wastewater Capacity of a Cedar Swamp
The response of water table to rainfall provided the basis for estimating the wastewater capacity of a northern Michigan cedar swamp which had been used for disposal of 30 million gallons...
Factors Influencing Oxygen Depletion in Green Bay
Dissolved oxygen depletion in the lower Fox River (Wisconsin) and Green Bay (Lake Michigan) have historically been tied to discharges of organic matter from municipal waste treatment plants...
Effect of Santa Rosa Lake on Ground Water Flow to the Pecos River, New Mexico
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa...
Agricultural Nonpoint Source Control Program for Lake Erie
Congress mandated (PL 92-500, Sec. 108d and 108e) that the U. S. Army Corps of Engineers design and develop a program for the rehabilitation and environmental repair of Lake Erie. The...
Attitudes of Decision Makers in the Great Lake States Regarding Large-Scale Diversions
The issue of diversion has motivated leaders in the Great Lake states to hold conferences, sign resolutions, and create a task force to discuss the ways in which the region can prohibit...
Low-Cost Stacked Block Revetments for Great Lakes Shores
Two stacked-block revetments, the product of emergency conditions and budget limitations, were constructed at Illinois Beach State Park on Lake Michigan in April 1982. The revetments,...
Large Basin Runoff Forecasting on Small Computers
The Great Lakes Environmental Research Laboratory (GLERL) developed a semiautomatic software package for making deterministic outlooks of basin moisture storage conditions, basin runoff,...
On-Line Hydrologic Simulation of Lake Conroe Reservoir Releases for Downstream Flood Control
Texas A&M Watershed Model (TAMWM) is used to simulate the response of the Lake Conroe watershed following a storm event and to develop an operational policy for flood releases...
Lake Water Level and Sediment Management?Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...
