Model for Water Quality in Periphery of Distribution Systems
A model is presented for water travel time and chlorine concentration in periphery dead ends of the water distribution system. The model is developed under the premise that residential...
Interruptible Option Contracts
Interruptible option contracts have been proposed and studied in numerous parts of the Western United States as an alternative supply option for water systems in an economically higher...
BASINS?A GIS-linked Watershed Analysis and Modeling Tool
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) is a GIS based tool developed by EPA's Office of Water to help States target and evaluate water...
Wetland Restoration in Southern North Sea Coastal Areas: The Experience of Britain and The Netherlands
Over the past 500 years, extensive reclamation of tidal wetland areas in the lowlands surrounding the Southern North Sea has taken place. In the Netherlands, reclamation has been an essential...
Water Based Land Use Regulations Using GIS Water Budgeting Model
Protection of water quality and supplies in developing watersheds requires maintenance of the natural water budget. Water budgeting model using GIS provides foundation for land use regulatory...
Sustainable Watershed Management in Developing Watersheds
In many parts of the country, land development at the fringe of major metropolitan areas has accelerated and is occurring in historically unprecedented land consuming patterns. This development...
Analyzing Water Balances and Ranking Maryland's Watersheds Related to Growth, Development and Loss of Habitat
One hundred thirty three watersheds comprising the entire state were analyzed for surface and ground water balance. Census population figures (1990) were allocated to the watersheds. Population...
Out of Control?
Once heroes in a popular battle against villainous despoilers of Mother Earth, to a growing chorus of observers environmental groups, EPA and other regulatory agencies have begun to look...
Water Water Everywhere
The city of San Diego is constructing a very large water reclamation plant that will use new methods to decontaminate water for industrial and agricultural uses. The plant is being built...
Rest in Peace
Engineers working on a subway connection project in the nation's capital successfully employed chemical grouting techniques--some never tried before--to protect a historically...
Optimal Groundwater Reclamation with Captial Costs
A dynamic optimal control model for groundwater remediation was extended to incorporate treatment facility capital costs. Incorporation of the capital costs had the greatest impact on...
Monitoring Water Quality and Use in Colorado
This paper presents the results of a two year study on the impact of irrigation water use on water quality near Greeley, CO. Data on irrigation application efficiency, deep percolation,...
Arizona Groundwater Management Alternatives
Sustainable groundwater management policies are examined through the use of a hydrologic-economic impact model of Arizona surface and groundwater use. Present water use practices were...
Statewide Consumptive Use Estimates
Methodology for estimating consumptive use and consumptive irrigation requirements on a statewide basis is summarized. The methodolgy has been used to update monthly and seasonal consumptive...
Surface Water Withdrawal Permits Programs for Humid Regions
In humid regions of the U.S., where control of surface water withdrawal is traditionally under the riparian doctrine, there are few strong regulatory programs to restrict water use. In...
Cooperative Game Theory in Water Resources
This paper presents a game theoretic framework for reassessing the operation and management of existing multi-purpose water projects subject to competing and conflicting water uses. Implicit...
Design Aspects of Modeling Reclaimed Water Use
The authors compare design aspects of modeling reclaimed water use with monthly and daily water balance protocols and review state regulations pertaining to use of reclaimed water. The...
Conservation Before and After: The Impacts of Increasing Block Rates on a Fully Metered System
Denver Water's inside residential consumption and revenues changed dramatically during a metering program and a conversion to inclining block rates. We analyze these two changes and make...
Wastewater Reclamation at Davenport, Washington
The City of Davenport, Washington went through an extended process to update their undersized wastewater treatment and irrigation reclamation systems for municipal wastewater. The process...
Administering a Regulated Riparian System of Water Rights
Western states, facing steadily increasing demands on limited water resources, have developed administrative regimes for regulating water use based on the judicially developed private...
