Controlling River Ice to Alleviate Ice Jam Flooding
Many communities affected by ice jam flooding have accepted the event as unpreventable. Others have approached their problem as one of open channel flow and implemented standard projects...
Modeling Intake Performance Under Frazil Ice Conditions
A water intake was modeled in a refrigerated flume in an active frazil icing environment in order to evaluate alternative modifications to the prototype structure. Tests were run until...
Fisheries Engineering Program at Washington State University
Problems associated with the interrelationships of instream hydraulic structures, and migratory and resident fish, are in need of better analysis and design. This improvement can be realized...
Reservoir System Management for Hydropower
A study was undertaken to develop a comprehensive reservoir operation simulation model of the Cumberland River Basin, located in the states of Kentucky and Tennessee. Hydropower production...
Artificially Varied Flow: River System Management
Some of the major water quality problems are heat, color, organic sediment, and total dissolved solids. To dilute these and other pollutants, substantial augmentation of flows for water...
SCS Water Supply Forecasting Opportunities
SCS personnel have been surveying the mountain snowpack, collecting other hydrometeorological data, and providing water supply forecasts to users for nearly 50 years. Recently, the snow...
Forecasting for Management of Spring Runoff in the Columbia River System
The National Weather Service, Corps of Engineers, and Bonneville Power Administration are affiliated in the 'Columbia River Forecast Service' (CRFS) to more efficiently...
The SNOTEL Data Acquisition System Design, Operation, and Uses
The Soil Conservation Service (SCS), U. S. Department of Agriculture, coordinates measurement of the winter snowpack in the Rockies, Sierra Nevada, Cascades, and other major mountain ranges...
Forecasting and Warning for Mt. St. Helens Streams
The eruption of Mt. St. Helens in southern Washington on May 18, 1980, created great devastation both by the blast itself and by mudflows generated by melting snow and ice. Several hydrologic...
Small Hydropower Development for Mining Industry
In deep mines, large refrigeration systems are employed to condition the working air to help control temperature and humidity. Large quantities of water are required to be brought into...
Power from a Water Supply System: A Resource Which Can Be Tapped
There are numerous water supply systems from which hydroelectric power could be developed without impending the regular operational schedule. The basic principle of operation is not different...
Incorporating a Hydro Plant into a Municipal Water System
While recently reformulating water use strategy and policy in association with the development of a new water supply reservoir, a large North Carolina municipality was prompted to assess...
Development of Toxic Screening Models for Surface Water Supplies
A major interest of the U. S. Environmental Protection Agency has been the assessment or ranking of vulnerable water utilities. Until recently, no techniques have been available that quantitatively...
Modifications of Dams for Recreational Boating
Many existing dams and river structures require modification, and new structures may need to include designs to allow safe white water activities. The basic problem is safety, with a long...
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...
Current Hydraulics Research at the Iowa Institute of Hydraulic Research
The Iowa Institute of Hydraulic Research is engaged in fundamental and applied research on a broad range of fluid mechanics and hydraulics problems. The history and organization of the...
Bureau of Reclamation Hydraulic Laboratory
The Bureau of Reclamation used hydraulic models for the first time in 1930 in the laboratory of the Colorado Agriculture Experimental Station in Fort Collins, Colorado. In 1946 the Reclamation...
