Weighting Factors for Transferable Discharge Permit Programs That Group Several Pollutants
Transferable discharge permit (TDP) programs for controlling several pollutants may manage such pollutants as several individual commodities or as a single weighted sum of the various...

Nonpoint Source Runoff and Urban Water Management
Urban nonpoint source pollution can be viewed from physiochemical, source, and impact perspectives. These and its dependence upon runoff pose important problems for pollution control management,...

Application of a GIS to Storm Water Quality Monitoring
Integration of an ARC/INFO geographic information system (GIS) with hydrodynamic water quality models (HEC-1 and HEC-5Q) helps quantify the water quality impacts of urban storm water runoff....

Stochastic Optimization of Conjunctive Use in Pakistan
This paper describes an optimization analysis of conjunctive use of ground and surface water that incorporates stochastic inflows and regional variations in groundwater quality and availability....

Real-Time Optimized Control of a Water Distribution System
The paper presents the design of a fully automated real-time computer control scheme for least cost operation of a water distribution system. The scheme includes modules for optimized...

Telemetry Data Considerations in Water Systems Control
The installation of increasingly sophisticated telemetry systems for data collection within the water supply and distribution networks has progressed rapidly in recent years. This has...

An Expert System for Control Curve Evaluation During Drought
This paper presents ongoing research into the automation of control curve generation and the development of an expert system for reservoir management for North West Water of Warrington,...

Minimizing the Risk of Unsuccessful Modeling Exercises
Monte Carlo simulation techniques were employed to relate input parameter uncertainties to the characteristics of model output accuracy and reliability, and to the probability of successfully...

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...

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...

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...

Water Reuse in Las Colinas, Irving, Texas
The largest urban water reclamation project in Texas that involves reuse of treated wastewater was implemented in July 1987, to provide an economical and drought-free supply of water to...

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...

Predicting Effects of Global Climate Change on Reservoir Water Quality and Fish Habitat
This paper demonstrates the use of general circulation models (GCMs) for assessing global climate change effects on reservoir water quality and illustrates that general conclusions about...

Modeling Groundwater Flow in San Joaquin Valley
Water supply, reallocation and conjunctive use options, within the San Joaquin and Tulare basins of the Central Valley of California, are being considered by Federal and State Planning...

Analysis of Uncertainty in Ground-Water Quality Monitoring Network Design
The paper reviews alternative approaches to ground-water quality monitoring network design. Four general approaches to network design are reviewed: (1) hydrogeologic, (2) simulation, (3)...

Optimization of a Groundwater Well Monitoring Network
An optimization model is presented for the design of a well monitoring network for groundwater quality and quantity parameters. The model utilizes a geostatistical procedure to estimate...

Modeling Volatile Organic Transport with Vapor Sorption
A flexible finite element simulation model is developed to predict the movement of volatile organic compounds in variably saturated subsurface regions. The model incorporates both the...

Groundwater Quality Network Design
This paper presents a methodology that uses optimization for designing a groundwater monitoring network. The methodology incorporates parameter estimation in conjunction with a numerical...
