A Physically Based Conceptual Model for Simulating Contaminant Levels in Subsurface Water
A conceptual physical model is developed to simulate solute transport and mixing in the vadose (unsaturated) and groundwater zones. The conceptual model couples lumped-parameters models...
Changes of Water Rights - The Colorado Experience
This paper describes engineering efforts which are involved with the judicial changes of water rights in the State of Colorado....
Integration of Water Rights and Salinity Considerations in Comprehensive River Basin Management
The TAMUWRAP Water Rights Analysis Package is a recently developed generalized reservoir/river system simulation model. Application of the model in a water supply reliability study of...
The Everett, Washington, Water Supply IRP
The City of Everett, Washington, supplies water to most of the population of Snohomish County, located just north of Seattle. The County is rapidly urbanizing, and preliminary review of...
Statistical and GIS Tools for Assessing Water Conservation Effects
The Automatic Meter Reading (AMR) devices provide us the ability to read a large number of meters in a short period of time. With the AMR we monitored weekly water consumption of several...
Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...
Simulating Water Supply Systems of the Raritan Basin
A recently developed interactive river-aquifer system model (IRAS) was used to study the Raritan River Basin as part of the effort to revise the New Jersey Statewide Water Supply Master...
Nakajima Subsurface Dam
A new water resource is generated by a subsurface dam. This paper presents the design, construction, and monitoring of a test subsurface dam in an alluvial valley of an island for both...
Designing Under Uncertainty When We Can Reduce Uncertainty: When is Another Observation Worth the Cost?
A method is presented that optimizes the selection of sites for observation of an uncertain parameter when that parameter is used in the risk-based design of an engineered system. The...
Convergence and Divergence Between Regulated Riparian and Prior Appropriation Provisions in the ASCE Model State Water Rights Code
Although there are two major American water rights systems-- riparian and prior appropriation--there are mixed systems and variations within each major type. The ASCE Model State Water...
Balancing Water Allocation and Water Quality: The Model State Water Code
The Model State Water Code (hereafter called the 'Code') currently being developed by an ASCE task committee is intended to provide a source of legal norms of water allocation for use...
Atmospheric Circulation and Snowpack in the Gunnison River Basin
Winter mean 700-millibar height anomalies over the eastern North Pacific Ocean and the western United States are related to variability in snowpack accumulations measured on or about April...
Climate Change Impacts on Boston's Water Supply
The analysis of the climate sensitivity of the water supply system of the Boston area indicates that the water supply has the potential to be dramatically altered by global warming. The...
Recreating a Process: The West Georgia Regional Water Supply Plan
This paper describes the planning process used to develop a long-range water supply plan for a five-county area northwest of Atlanta, Georgia. Demand for water in the study area is projected...
Water Policy and Management: Solving the Problems in Southern New Jersey
Southern New Jersey, which has relied solely on groundwater to satisfy its water supply needs, is depleting the primary source for that water. Symptoms of this depletion include declining...
Water Policy Change, Implications for Pyramid Lake
Pyramid Lake is part of and is surrounded by the Pyramid Lake Indian Reservation. The river system has been administered by a Federal water master serving the Federal court system with...
Understanding the Uses of History in Water Resources Planning and Management
Understanding how water resources decisions (technical, regulatory, structural, or managerial) have been made is necessary to provide the water industry with a perception of complex human...
Involving the Public to Reach Consensus in Water Resources Projects - An Interdisciplinary Perspective
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the reliability of the county's water supply in the event of an extreme emergency,...
Willingness-to-Pay for Alternative Shortage Probability Distributions
Mathematical programming is used to derive estimates of the willingness-to-pay of water service customers for improvements in water supply reliability. Reliability is represented as a...
Joint Optimization of Groundwater Remediation and Monitoring
We describe the challenge of devising optimization methods which optimize jointly the remediation and monitoring at a contaminated site. We refer to the dual control method as a promising...
