The City of Salem, Oregon is developing an Aquifer Storage and Recovery (ASR) system to provide a 20 mgd capacity, 440 mg volume, emergency storage and peak day supplementary supply. When...
Volunteer Organizations Use of Appropriate Technology in Developing Countries
The water and sanitation needs facing developing countries are formidable. This paper discusses the experience of a volunteer organization, the Water and Sanitation Consultancy Group,...
Eastern San Joaquin County Groundwater Management
An aquifer system of significant volume is located in Eastern San Joaquin County (ESJC), part of California's Central Valley. The industry in that region is primarily agriculture,...
Management of Stream-Aquifer Systems in the 21st Century
Many water agencies, especially those in the arid and semi-arid southwest of United States rely on stream-aquifer systems for a significant proportion of their water supplies. Wastewater...
Groundwater Flow Component of a Wetland-Dynamics Model
A 3-D groundwater flow model was developed to study the hydrology of groundwater-fed wetlands. Initial model results, including steady and unsteady simulations, compare well with existing...
San Diego County Water Authority's Emergency Storage Project: A Major Planning Achievement
The San Diego County Water Authority (Authority) has been actively working to maximize the security of the future water needs of the community it serves. The Emergency Storage Project...
The Standley Lake Protection Project
Until recently, there has been no physical separation between potentially contaminated runoff from the former Rocky Flats Nuclear Weapons Plant and Standley Lake, the nearby water supply...
Hydrodynamic Changes Associated with Navigation Traffic on the Upper Mississippi River System
Research has been conducted at the Illinois State Water Survey for the last five to seven years to collect field data from the Illinois and Mississippi Rivers to determine the extent and...
Better Management in the Water Supply Sector Through Indigenous Institutions
The following discussion briefly explores how improved institutional performance in Africa's water sector can be promoted through reconciliation of indigenous and formal institutions....
Wastewater Reuse: An Alternative for Potable Water
Adverse economic conditions throughout the world have resulted in a shift of priorities causing water supply and sanitation schemes to relegate down the list of adequately funded projects....
Sacramento Valley Conjunctive Use?Future Water Supply for the State Water Project?
In 1992, the California Department of Water Resources began an investigation of the potential to develop additional water supply for the State Water Project through conjunctive use programs...
Implementing a Successful Conjunctive Use Program
Over the past decade, water planners have come to the agreement that conjunctive use is a good strategy to help meet present and ftiture water needs. Storing water underground has many...
Analysis of Long-term Supply-demand Planning of Water Resources in Taiwan
The purpose of the present study is to analyze the long-term supply-demand planning of water resources in Taiwan under future conditions. Since last decade, the Water Resources Planning...
Risk Analysis of Joint Reservoir Operation in Central Taiwan
Risk analysis for shortage of water on the joint operation of Li-Yu-Tan Reservoir and Shih-Kang Dam (Reservoir) in central Taiwan is presented in this paper. Deter ministic simulation,...
Development of Islandwide Groundwater Pollution Potential for Taiwan
Using the modified DRASTIC and existing and newly surveyed data, groundwater pollution potentials for all 10 groundwater basins in Taiwan were calculated on 2 km by 2 km grids. This paper...
Transboundary Diversions, Water Law and Property Rights
Meeting water supply needs associated with population growth will require the increasing use of transboundary diversions of water. To regulate and control these diversions, both eastern...
Development and Implementation of a Capital Improvement Program for a Small Water Utility
The City of Las Cruces water utilities is being exposed to accelerated population growth and is faced with inadequate capital infrastructure to meet increasing demands. The City's...
Changes in Ground Water?Surface Water Interaction in the Santa Ana River Caused by Independent Water Resources Management Activities
For the past 18 years, ground water artificially-stored in the Chino Basin, has been managed as a zero-interest bank account. Recent water resources management studies show that losses...
Optimization Modeling of Complex Surface Water Collection Systems
The New York City (NYC) water supply system is currently being modeled using Linear Programming (LP) optimization techniques. A series of simulations were performed to investigate the...
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...
