Owens Valley, California Basin Management to Meet Both Water Resources and Environmental Goals
The City of Los Angeles imports over 60 percent of its water supply from the Owens River Watershed as part of the resources used in serving 3. 5 million people. As part of this operation,...
Mangement Studies of Farmington Bay, Great Salt Lake
The primary objective of this study is to evaluate management options for the Farmington Bay area of the Great Salt Lake in terms of water quantity and quality. For the study, it was assumed...
The Water Problems on the Penghu Islands in Taiwan
The Phengu Archipelago in the Taiwan Straits is composed of Pleistocene basalt with the accumulation of coral reefs without any significantly mountainous terrain on any of the islands....
Water System Reliability?Balance of Cost and Risk
Reliability of water distribution systems to perform adequately during stress situations is dependent both on operation/maintenance preparedness as well as the limitations of the physical...
Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...
Ground Water Strategy in California
There is great debate over when and how much new water California needs. Yet of the backbone supply, wells that could serve over 1 million people have been either removed from use or blended...
The Role of Local Government in Water Quality Management
To meet the challenge of providing safe drinking water at a reasonable cost, local governments, together with water utilities, must do more than merely fund the implementation of state...
What About the Point-of-Use?
Point-of-use (POU) granular activated carbon (GAC) treatment devices are being installed more frequently on community water sytems and on private wells. This article describes carbon filter...
Conjunctive Water Use Planning
The phase 'conjunctive use' refers to the integrated management of various water resources within a river basin or other geographic region. The objectives of...
A New Dam in California?Piece-of-Cake!
It initially appeared that a series of insurmountable roadblocks would prevent the City of Morro Bay from constructing a new dam and water supply reservoir on San Bernardo Creek near the...
Policy Screening Models for Water Supply Operation
It is possible to characterize the real time, short term operation of a metropolitan water supply system - including the surface and groundwater sources, treatment and pumping facilities,...
Flow and Sediment Transport in Curved Channels with Nonuniform Bed Material
Described is a scheme for controlling the exchange of grain sizes between bed and bed load in a curved alluvial channel. The scheme is an integral part of a model for simulating spatial...
Development of the Nauvoo Point Plant Beds
In Pool 19, Mississippi River, the accumulation of sediment has resulted in soft-substrate benthic communities or macrophyte beds. Three areas in the downstream 12 miles of the 46. 3 mile...
Taming a Pipe Network Analysis Computer Program
The use of a conventional network analysis computer program as an effective evaluation tool for routine operation of an existing water distribution system has several practical limitations...
Automated Control for Central Arizona Project Distribution Systems
Computer based automatic control for three extensive open channel water distribution systems is described. Radio telemetry allows a central computer to execute control logic at individual...
Energy Dissipation in Small Canals
Two approaches are used for energy dissipation in channels. In the first, the water is allowed to drop, thereby converting potential energy to kinetic energy. This excess energy is then...
Evolution of Water Organisations in England and Wales
Although by the early 1960's there was in existence a large body of legislation dealing with water matters, the Water Resources Act 1963 provided for the first time a significent...
Obstacles to Establishing an Effective Water Resources Planning Process in Developing Countries
Four obstacles stand in the way of effective planning: lack of agreement among participants on practical operating principles; misuse of local money-making opportunities by foreign contractors...
Benefit-Cost Evaluation of Minimum Instream Flows
In many cases, determinations of minimum desirable instream flows (MIF) are made without full consideration of economic costs and benefits. Benefits are frequently quantified in nonmonetary...
Water Supply and Sewage Disposal: Shanghai, China
This paper describes a joint research effort which took place between the Shanghai Bureau of Environmental Protection, Tsinghua University (Beijing), and the University of Michigan. The...
