A Travel Time Template for Water Body Field Surveys
A LOTUS 1-2-3 spreadsheet application has been developed to help plan water body surveys. The template calculates travel times between sampling stations and outputs a time schedule for...
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....
Tucson, Arizona's 110-Year Water Resources Plan
The desert community of Tucson, Arizona, has just completed a state-mandated 110-year water supply plan. The plan includes conjunctive use of local groundwater and surface water imported...
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....
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...
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...
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...
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...
Groundwater Modeling of the Tustin/Irvine Basin
This paper describes the results of groundwater modeling in the Tustin/Irvine basin situated in the southeastern portion of the Tustin plain, which is the the southern extension of the...
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...
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)...
