Water Demand Forecast Uncertainty
This paper examines the effect of water demand forecast uncertainty on the operation of a city's water supply system. It is based on a number of years experience the author...
Underground Storage in Urban Stormwater Management
The use of underground pipe detention basins is discussed. These basins mitigate the frequency of localized flooding and sewer surcharging by effectively increasing the flow capacity of...
Resolving a Groundwater Conflict in Colorado
In 1985, the City of Lakewood, Colorado, submitted applications for permits to drill 20 wells in the Arapahoe Aquifer with the intent of appropriating 4300 acre-feet annually for eventual...
Resolution of Conflicts in Superfund Site Cleanups
In this paper, we present the typical sequence of tasks involved in the cleanup of a Superfund site under current regulations and guidance. We then pinpoint the areas where conflicts arise...
Administration of Water in the 21st Century in Accordance with the Appropriation Doctrine
In accordance with the appropriation doctrine it appears straightforward to distribute water during below-average supply, 'first in time of use, first in right of use'....
BMPs for Urban Stormwater Management in Virginia
This paper presents discussions on applying best management practices (BMPs) in Virginia as part of the Chesapeake Bay clean up program and future information needs....
Field Testing of Selected Urban BMP's
This paper presents the results of field sampling of two urban BMP's (Best Management Practice), namely, a wet detention pond and a level spreader/vegetative buffer strip...
Stormwater Management in Virginia
In the 1986 budget bill, the Virginia General Assembly directed the Virginia Department of Conservation and Natural Resources, Division of Soil and Water Conservation, to conduct a review...
GWPATH: Ground-Water Flow Path Analysis
GWPATH is an interactive software package for estimating horizontal fluid pathlines and travel time in fully saturated groundwater flow domains. GWPATH was developed for the IBM PC-AT...
A Vectorized Polynomial Preconditioned Conjugate Gradient Solver Package for the USGS 3-D Ground-Water Model
A vectorized polynomial preconditioned conjugate gradient (PPCG) numerical algorithm is presented as an additional solver package interfaced with the Modular Three-Dimensional Finite Difference...
Reported Results from 600 Cloud Seeding Projects
The authors conclude that cloud seeding is an effective way of increasing precipitation when applied to the appropriate clouds and climate. Reported results from research projects show...
Comparison of Storm Water Management for Phoenix and Washington, D.C. Urban Areas
The design criteria, the methods of analyses, and the estimated costs of construction are compared for two storm water management systems in the Phoenix, Arizona and the Washington, D.C....
Computer Based Master Plans Manage Water Resources
Scottsdale is pursuing water and wastewater master planning with the goal of implementing a proactive water resources management policy. To prepare dynamic master plans with the above...
Risk Assessment of Lake Shore Development of Devils Lake, North Dakota
In recent years, the advent of the flood insurance programs has forced developers, financiers, and planners to deal with future high water conditions and associated risks. A reliable method...
Vacuum Sewers: Fundamentals and Design Methods
Vacuum sewer (VS) systems have important advantages over conventional gravity sanitary sewers or septic tank-soil absorption systems when one or more of the following conditions hold:...
Alternating Direction Oxidation Ditches?A Cost Saving Technology from Denmark
A soon to be released EPA report claims that in Denmark, small alternating direction oxidation ditches (ADOD) save as much as 70% of the cost for conventional oxidation ditches. The alternating...
CLNET?A Computer Model for Tracking Movement, Decay, and Concentrations Throughout Water Distribution Systems
This paper describes a computer program package for modeling the spread and subsequent decay of chlorine for modeling as water travels throughout a water distribution system. This total...
Issues in Regional Water Resources Planning and Management: A Great Lakes Case Study
This paper focuses on the obstacles and opportunities inherent in regional resource management efforts, with the Great Lakes Basin serving as a case study. The following areas are addressed:...
Statistical Modeling of Space-Time Data
A common practice in hydrogeology is to draw contour lines to depict the occurrence of spatially distributed (i.e., regionalized) variables such as groundwater elevations, aquifer properties...
Movement of Chloride Ions in a Saturated Soil Sample
A series of laboratory experiments were performed to demonstrate and track the migration of chloride ions in saturated soil samples undergoing freezing. Results from these experiments...
