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...
Parameter Identification in Water System Models
Parameter identification (PI) is an automatic model calibration technique with which the unknown physical parameters in a mathematical model are determined from a constrained optimization...
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...
Fate and Transport of Metals in a River System
A steady-state model was developed that describes the fate of metals in a shallow river system. Settling and resuspension of solids were defined through empirical equations relating a...
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...
Uncertainty in Unsaturated Zone Pollutant Transport
The portion of a pollutant spill transported to an underlying aquifer is uncertain due to the stochastic nature of precipitation and uncertainty in the geochemical properties of the contaminant...
Statewide Port Assessment?Louisiana Case
The Louisiana Statewide Ports Assessment (LSPA) has been conducted of significant changes in the economic environment of the State, Nation and world, which influences not only trade patterns...
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...
Sand Rights A Legal System to Protect The Shores of the Beach
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...
Examples of Sediment Distribution in the Italian Adriatic Coast. A Comparison Between the Shepard and the Nota Textural Classifications
Four sectors of the western Adriatic coast, each with a different feature, represent the test areas to evidence the differences between the two textural classifications of sediments by...
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...
Sand for Beach Nourishment in Lower Chesapeake Bay
The Virginia Institute of Marine Science designed and performed an inventory of the resources of sand in the southernmost portion of Chesapeake Bay. The primary purpose of the project...
