Instituting Increasing Block Rate Pricing as a Water Conservation Measure
The objective of this paper is to demonstrate the benefits of an increasing block rate pricing policy as a water conservation measure. By changing the pricing structure, demands will change...
Great Lakes Levels: Toward Systematic Decision Making
The International Joint Commission (IJC) has authority given by the governments of Canada and the United States to use existing works to regulate the lakes system according to agreed-to...
Application of a GIS to a Ground Water Classification System
New more effective methods of ground water management are being developed by the New Jersey Department of Environmental Protection (NJDEP) including an anticipatory conceptual State ground...
TRUMPET: A TR20plus Watershed Model?Version 1.04
The TRUMPET watershed model is a microcomputer application which expands upon the widely used SCS TR20 hydrology computer program by providing user-friendly, interactive input and file...
An Investigation into Causes of Bank Caving
A series of investigations into bank caving along the Ohio River are described. These investigations include a study of the distribution of precipitation in the study region, derivation...
Forecast Uncertainty in Reservoir Operation
Bayesian decision theory can be of significant value to reservoir operation because of its flexibility in being able to incorporate new information and/or opinions and judgments of decision...
Water Demand Forecasting in Southern California
A study of annual water use in Southern California is made in order to determine the cause of unusually high demands in 1987. Regression analysis of the demands and analysis of ratios...
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...
Continuous Drainage System Modeling of Jones Run
A generalized package of hydrologic and hydraulic models has been developed for the quantitative analysis of watersheds and drainage networks. The package is called ODWAP (the Old Dominion...
Virginia Case Studies of Risk Based Drainage Design
The goal of this paper is to apply a practical engineering risk-based method of design of pavement and surface drainage systems to three Virginia case studies. The target systems include...
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...
Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...
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....
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...
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...
Introducing Geostatistics?Estimating Spatial Data
The theory of regionalized variables commonly known as geostatistics is now being applied throughout the community of engineering and sciences. Measurements taken at different locations,...
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...
Rolling Incinerators
The Illinois Environmental Protection Agency (IEPA) is using a mobile incinerator to clean up a former oil and solvent storage/transfer operation which was badly contaminated. The benefits...
Drawing up Waterproof Curtains
Curtain wall damage has recently become the number one source of building owner complaints. Until wall systems are designed with backup water collection systems and other details, leakage...
Skytrain Crosses the River
The cable stayed bridge that will carry Vancouver's light rail line across the Fraser River is the world's longest such bridge built solely for mass transit....
