The quality of natural and induced storm water runoff from Oahu's Honolulu International Airport (HIA) and four outer island airports in Hawaii was evaluated for water supply...
Dual Source Water Supply Facilitates Power Plant Start-Up
The make-up cooling water supply for a four unit coal-fired steam turbine generating station required a peak demand of 28,000 gallons per minute (62. 4 cubic feet per second). Following...
A Systems Approach to the Assessment of Water Supply, Treatment, Storage and Distribution Systems
To focus on the needs of a system at present and in the future and to foresee potential problem areas prior to their occurrence, it is advisable for the management of a water utility to...
Studying Water System Operation by Computer
Computer modeling can greatly improve the planning and operation of water systems at relatively low cost. Time-dependent water system models can be used to refine improvements to a water...
Reservoir Planning Using Marketable Water Rights
The needs and approaches for developing efficient methods for the allocation of natural water supplies and efficient planning methods for the design and operation of reservoirs and other...

Ongoing activities in hydraulics research at the U. S. Army Engineer Waterways Experiment Station are described. The various areas in which research is under way are enumerated. Activities...
Will Southern California Revert to a Desert?
The nearly 13 million people in Southern California - one-half of California's population - face the prospect of water shortages in the near future. These people depend on...
Special Drought Operations of Oroville Reservoir
Special operations of Oroville Reservoir during the 1976-77 California drought resulted in good spawning conditions in the Feather River for migrating king salmon. Special cold water releases...
Development of the Rio De La Plata Hydrographic Basin
The rivers and climate of the basin are described. Available and developed hydropower sites are presented. The international consequences of various water management schemes are discussed....
Fluorescent Tracer Mixing Experiments in Glenmore Reservoir, Calgary
Mixing studies using salt and dye as tracers were conducted in Glenmore Reservoir which is the major water supply for the City of Calgary, Alberta. The purpose of the studies was to find...
Economics and Groundwater
The increasing use of groundwater has resulted in greater lifts, and coupled with increased energy costs is focusing more attention on the economics of groundwater use. The proceedings...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
Superhydro
In 1986, when its six turbine/pump-generator/motor units will be in operation, the Bath County Pumped Storage Hydroelectric Project in Virginia will be the world's largest....
Evaluating Pump Characteristics in Developing Countries
How do you assess normal operating characteristics for pumps used in small water supply systems when no information on the pumps is available and when the technicians have little technical...
Itaipu, South America's Grande Dame
When fully operational, the Itaipu hydropower project, located along the Parana River between Brazil and Paraguay, will be the world's largest. In 1989, it is expected to...
Research Needs Related to the Nation's Infrastructure
The engineering community, which designs and constructs infrastructure facilities, must look for innovative ways to do a more efficient job. Although some research has focused on problems...
Infrastructure Crisis: What the Media Are Saying
In the past year and a half the national media have performed the major role in spreading the word that the nation's public works, particularly in urban areas, have been neglected...
