Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...
Effects of Irrigated Agriculture on Groundwater Quality in the Corn Belt and Lake States
Irrigation of croplands has the potential to increase the rates at which water soluble substances are leached from soil into underlying aquifers. This paper evaluates the impact of irrigated...
Mangement Studies of Farmington Bay, Great Salt Lake
The primary objective of this study is to evaluate management options for the Farmington Bay area of the Great Salt Lake in terms of water quantity and quality. For the study, it was assumed...
Water Quality and Hydrodynamics in a Shallow Lake
Hydrodynamics and water quality are closely coupled in a shallow lake via horizontal transport and sediment resuspension. The latter process is examined thru modeling and in situ field...
Implications of Nitrogen Transport by the Okanagan River
The long-term mean of total nitrogen load estimated in the river channel above the inlet to Skaha Lake is 906 lb day** minus **1. The apportionment of ammonia and nitrate plus nitrite...
A Computer Model for Oil Slick Transport in Rivers
A computer model for simulating oil slick transport in rivers is presented. In the model the effects of advection, spreading, evaporation, and dissolution on the transformation of an oil...
Interaction Between the Technical and Political Processes in Solving Flooding Problems at the Great Salt Lake, Utah
The Great Salt Lake occupies the lowest point in a drainage basin of approximately 22,000 mi**2 (57000 km**2). Inflows to the lake occur as surface runoff, groundwater flows, and precipitation...
Changes in Management: International Great Lakes
Unprecedented changes in the binational management of the Great Lakes are underway. Problems and programs to solve them increasingly are being considered on an ecosystem (comprehensive,...
Seattle's Central Waterfront
The character and identity of Seattle are based largely on its extensive waterfront areas. The city has approximately 90 miles of shoreline, one of the benefits of possessing a varied...
Reflections on Racine's Rebound
The existing harbor in Racine has approximately 110 acres of water surface bounded on the north and south side by one-half -mile long concrete breakwaters and on the west by the city....
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...
Design and Testing of a 400 Ft Span Plate Girder Bridge
The paper describes design features and testing of the Madawaska River Bridge. The bridge is unique in being the longest span plate girder bridge in Ontario, having continuous spans of...
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...
