Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...
Optimal Rehabilitation Model for Water Distribution Systems
The objective of this paper is to describe a new methodology which can select the pipes to be rehabilitated and/or replaced in an existing water distribution system and determine how much...
Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...
Watershed Management at Three Governmental Levels
Examples of holistic water resources management by the federal, state, and local levels of government illustrate practical application of basic principles of watershed management and public...
A Watershed Approach to Water Quality Criteria
Water quality has been managed historically using water quality criteria implemented through the NPDES permitting process. Many water bodies have water quality better than that defined...
The Impact of Global Warming on Water Resources: Overview and Implications for Coastal California
In the past two years, impressive evidence has accumulated that global warming is occurring and is related to the increase in greenhouse gasses. The impact of the warming process on water...
Impacts of El Ni?o in Western Washington
The climatic phenomenon called El Nino is described, and its impact on hydrologic conditions in western Washington is shown for two recent events. Impacts on water management during the...
A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...
Integrated Water Resource Planning?A Northwest Case Study
The City of Tacoma Water Division recently incorporated integrated resource planning into its comprehensive water system planning process. This method of planning considers demand-side...
Ground Water Management Standards and Protection Tools
Once local goals and objectives for ground-water protection have been defined, wellhead protection areas delineated, sources of contamination inventoried and assessed, management techniques...
A Planning Strategy for Safe Drinking Water Act Compliance
This paper presents a simple planning strategy for drinking water utilities that will allow them to move ahead with system upgrades and specific regulatory compliance programs even though...
National Study of Water Management During Drought Results Oriented Water Resources Management
This paper provides an overview of a four year national study of water management during drought and builds a foundation for the other papers in this mini-symposium. The primary objective...
Empowering Stakeholders Through Simulation in Water Resources Planning
During the past two years, researchers at the University of Washington (UW) have had the unique opportunity to facilitate and observe the development of drought planning activities associated...
The Potomac Experience?A Forerunner of DPS
Thirty years ago, dramatic events were about to begin in Potomac River basin with the publication of a report of study recommending 16 major reservoirs and hundreds of small ones to solve...
The Challenges of Interstate Water Planning and Management
This study is one of four primary basin studies as part of the U.S. Army Corps of Engineers National Study of Water Management During Drought, a four year study initiated after the Drought...
The James River Case Study
The James River was selected as a case study for the National Drought Study because it provided an example of an Eastern (riparian) river basin with relatively little storage, increasingly...
The Role of Object Oriented Simulation Models in the Drought Preparedness Studies
One of the major activities in the U.S. Army Corps of Engineers, Drought Preparedness Studies (DPS) has been the development of water resource simulation models for each study site. This...
Demonstrating Competition for a Limited Resource in the Cedar/Green Basins
An object oriented model building tool is used to develop two river basin simulation models. The models will be used to help manage the water resource during dry years in the Cedar and...
Including Expert System Decisions in a Numerical Model of a Multi-Lake System Using STELLA
During the drought of 1988, water users in the Kanawha River, West Virginia, became painfully aware of conflicting uses that have developed since the 1970s. A numerical modeling of the...
Multiparty Model Development Using Object-Oriented Programming
The Massachusetts Water Resources Authority (MWRA) has taken advantage of recent advances in object oriented programming to build a flexible input and output model of its water supply...
