Optimizing Dallas' Multiple Reservoir Supply System
Dallas Water Utilities (DWU) applies a mathematical computer model of its reservoir supply system to assist in making operational decisions to optimize supply operations. The model considers...
Microcomputer Tools for the Management of a Multiple Reservoir Water Supply System
In a Raw Water Management Plan study performed for the City of Newport News Waterworks, Camp Dresser & McKee developed a series of micro-computer programs that allow the City to...
Storage Reallocation Evaluation for Reservoir System
Reservoir storage capacity is allocated to various purposes prior to project construction. However, changing needs and conditions may warrant later conversion of storage capacity from...
Benefit/Cost Analysis of Stormwater Detention Systems
In the past, detention basins have been designed to control peak discharge rates. However, there is considerable interest in using the detention basin for control of nonpoint source pollution....
Reliance on Structural Controls for Water Supply Protection in Urbanizing Watersheds
The watershed is the source of pollutants which can contaminate the water supply reservoir. It is far preferable to implement an affordable watershed management plan that keeps contaminants...
Considerations for a Multiple-Use Stormwater Detention Facility
A 60-year-old neighborhood provides the unusual setting for the City of Tulsa's Turner Park-Will Rogers High School Stormwater Detention Facility. The 20-acre site is located...
The Genesis of Surface Water for San Antonio
San Antonio is the ninth largest city in the United States and the only one of that group that relies exclusively on groundwater. The Applewhite Water Supply Project is the first surface...
Groundwater Contamination from an Unlined, Poorly Capped Landfill
This paper presents a case study of groundwater and surface water contamination from a major, unlined, and poorly capped municipal landfill located in Western Washington. The landfill...
The Market Value of Water in the Ogallala Aquifer as Implied by Recent Farm Sales
As indicated by farm sales in the Ogallala region, the value of water in the Ogallala Aquifer has fallen. Market values have declined by 30 to 60%, following the recent downward trends...
Fuzzy Sets in Civil Engineering?A Tutorial
This tutorial is an introduction to the theory of fuzzy sets and its applications in Civil Engineering, including its use within the framework of knowledge-based systems. The techniques...
Risk Management for Groundwater Contamination: Fuzzy Set Approach
A methodology is developed for health risk management under uncertainty, using fuzzy sets. Groundwater nitrate contamination illustrates the methodology. A risk management framework is...
Bayesian Decision Theory and Fuzzy Sets Theory in Systems Operation
Operation of Water Resources Systems involves complex set of human decision. Many of the parameters involved in systems operations are random functions of time. Sometimes, the data needed...
Reservoir Reevaluation in TVA
Demands for the use of dams and reservoirs tend to change after the projects are completed. The Tennessee Valley Authority (TVA) works with State and local groups to try to increase the...
A Rational Basis for Determining Safety of Containment
Design of waste containment facilities may follow one of three tacts: (1) the liner and cover systems may have prescribed components of predetermined minimum thicknesses and hydraulic...
Estimating Earthquake Hazard of Municipal Water Systems
This paper uses the City of Memphis as a case study to present the seismic hazard evaluation of a municipal water delivery system. The horizontal peak bedrock accelerations resulting from...
Effects & Risk Analysis for Time Variable Exposures
The effects of toxicants on organisms in natural settings are a function of both the variations in exposure concentrations and duration of exposure. This paper present analysis procedures...
Water Measurement and Accounting of Lake Michigan Diversion
The diversion of water from Lake Michigan and the Lake Michigan Basin into the Mississippi River Basin has been regulated since the turn of the century. The U.S. Supreme Court Decree of...
Measuring Benefits of Water Supply Projects
Various approaches are used to determine the value of water supply projects. Deterministic methods will lead to biased valuation of additional supplies of water. Calculation of risk premium...
Contracting Provisions to Delay Capital Expenditures and Extend the Use of Available Water Supplies
A contractual means has been established of assuring equitable use of available water supply by the regional participants in the Williamson County Raw Water Line Project. A contract between...
Design of Sampling Networks for Water Table Monitoring
In the application to the monitoring of water tables the presence of temporal and spatial dependence is of crucial importance. Often the network will be used to collect data to estimate...
