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...

Reduction of Intake Flow Due to Ice Rubbling and Consolidation
Numerous seawater intakes have been designed for Arctic Coastal Waters. In these areas moving ice often causes rubbling and pile up of broken ice pieces against the shore. If this forms...

Hydraulics of Freeze-up
A classification scheme for freeze-up of a river is proposed based upon the response of indicated stage. A conceptual model is developed to describe the course of the indicated responses....

A Quantitative Assessment of Surface Water Resources for Coal Slurry Pipelines Originating in Southwest Virginia
In view of the high streamflow variability, preliminary quantitative assessment was made of the capacity requirements and low-flow frequency characteristics of offstream reservoirs needed...

River Basin Management: Role of Hydraulics and Hydrology
One of the major Illinois rivers originates in a neighboring state. The main stem of the river was channelized about 65 years ago, and is considered to be a 'drainage ditch....

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...

LTER and Management of the Upper Mississippi River
The Upper Mississippi River is managed for multiple use by two federal agencies and five states. System management objectives include commercial navigation, commercial fisheries, minimum...

Effects of Resource Development on Water Quality in the Big South Fork National River and Recreation Area, Tennessee and Kentucky
The South Fork Cumberland River begins in Tennessee at the confluence of the New River and Clear Fork. Strip mining for coal in the New River basin has been ongoing for decades with little...

Nebraska's Shrinking Platte River Channel: Biological Aspects and Implications
Since the completion of major water projects along Nebraska's Platte River system in 1941, vegetative encroachment and channel narrowing have substantially altered the central...

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...

Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...

Sedimentation in Small Hydropower Reservoirs
Small-scale hydropower projects, which usually include reservoirs of limited size, may inherently incorporate severe sedimentation problems. The ratio of reservoir volume to sediment inflow...

Planning a Resource-Compatible Low Head Waterpower Development
Responsible development of waterpower potential is a significant aspect of comprehensive water resource planning. Recent interest in small scale hydro projects has generated concern among...

Hannibal Hydroelectric Project Ecological Concerns
In January, 1983 the City of New Martinsville, West Virginia filed a license application with the Federal Energy Regulatory Commission (FERC) to construct and operate a 34 MW hydroelectric...

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...

Research in Hydraulics at California Institute of Technology
Activities are centered in the W. M. Keck Laboratory of Hydraulics and Water Resources. Research projects active at the Laboratory reflect a continuing commitment to traditional areas...

Current Research in Hydraulics at the Corps of Engineers Waterways Experiment Station
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...

Hydraulic Research--U.S. Geological Survey
Research at the Gulf Coast Hydroscience Center near Bay St. Louis, Mississippi, is being conducted in an indoor laboratory, and an outdoor laboratory. Much of the current indoor lab research...
