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....
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...
Large Scale Water Resources Systems Planning-Approach and Case Study
Planning approach for large scale water resource systems planning backed by models has been developed. Four hierarchial stages are identified and mulitlevel multiobjective models have...
Reliability and Risk Assessment for Water Supply Systems
Analytical methods for computing the reliability of water supply systems are described and demonstrated. A case study serves to show how risk, which is the economic loss due to shortfalls,...
The SRI Technique for Flood Frequency Analysis
This paper presents a technique for flood flow frequency analysis called the Storm Response Index (SRI), and a case study using the technique. The SRI method is based on the development...
A Case Study of Ground Water Quality Protection in California
Incidents of ground water contamination from improper disposal of industrial wastewater have been widespread throughout California. In late 1984 the State Water Resources Control Board...
Emerging Environmental Clean-Up Responsibility
This paper is a summary of the structure of regulations requiring clean-up of sites when closed or sold, specifically the State of New Jersey's Environmental Cleanup Responsibility...
True Cost Comparison of Landfilling and Incineration of Hazardous Wastes
An analysis of the 'true' costs of a series of discrete model situations representing hazardous waste management by landfilling and incineration was conducted....
A Systems Approach for Wasteload Allocations
A methodology for determining an optimal periodic permit for a single discharger situation was developed which accounts for effluent variability, as well as the variability of the receiving...
Direct Filtration of a Semiconductor Wastewater
A pilot plant study was conducted to determine the feasibility of direct filtration for the removal of metal precipitates from a semiconductor manufacturing wastewater. The pH of the acidic...
Treatment Plant Comparisons in Removing Molecular Weight Fractions of THM Precursors
This paper describes the performance of several types of water treatment plants in removing various molecular weight fractions of natural occurring aquatic organic matter, some of which...
Coastal Management Problems in the United Kingdom
Five case-studies from the East coast of England illustrate some of the obstacles facing more enlightened coastal management in the United Kingdom. All the examples demonstrate unsatisfactory...
Analysis of Odors from Polluted Bay Ecosystems
Facility effluents, runoff, sewage and manmade constituents entering bays and streams can provide a source of nutrients which can support the growth of odor producing benthic or planktonic...
The Arcata Marshes: A Case Study in Wetland Restoration
In Humboldt County, California, the City of Arcata has developed an innovative wetland restoration program. The three major projects were funded by the State Coastal Conservancy and consist...
Ocean Dumping at the Philadelphia Site; A Case Study
This study reviews the results of eleven years of investigation of the impact of ocean disposal of sewage sludge at the Philadelphia dumpsite. The site, located on the continental shelf...
The Protection and Management of Cultural Resources Through State Coastal Management Programs?A North Carolina Case Study
North Carolina's coastal management program attempts to protect and manage a broad spectrum of the state's coastal resources. These resources range from valuable...
Environmental Mitigation Planning for Impacts on Salt Marsh
This paper discusses two projects constructed or proposed on tracts which contain coastal wetland areas of environmental significance. Without proper planning, the impacts of these developments...
Studies in an Unproductive Coastal Lagoon in South Texas: A Case Against One-Time Sampling for Environmental Assessments
This study illustrates the problems inherent in attempting to write an environmental assessment based on inadequate or misleading data. Results can be biased against environmental preservation...
Mitigating Environmental Losses Through Project Planning
A significant amount of industry effort goes into project planning prior to preparation and submission of a permit application. Baseline studies are conducted, including preparation of...
Henderson Marsh Mitigation Agreement
The Henderson Marsh Mitigation Agreement is a legal document entered into by the U. S. Fish and Wildlife Service (USFWS), the Oregon Department of Fish and Wildlife (ODFW), and the Weyerhauser...
