Mathematical Modeling of River Ice Process
Computer modeling of flow and ice conditions in a river is an important element in the planning of water resources project in northern regions. River ice processes are closely related...
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...
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....
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...
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...
Nebraska's Shrinking Platte River Channel: Hydrologic Aspects and Implications
Biologists have proposed two hypotheses to explain recent channel narrowing and vegetative growth in flood plain habitat areas along the Platte River in Nebraska. One group contends, without...
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...
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...
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...
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...
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....
Modeling Pool and Riffle Sequences in Alluvial Channels
A one-dimensional mathematical model has been developed to predict the hydraulic characteristics of alluvial channels under low flow conditions. For a given steady discharge, channel geometry,...
Kinematic Shock: A Sensitivity Analysis
A series of numerical experiments is performed to determine the flow and channel characteristics that are most conducive to kinematic wave steepening and associated shock phenomena. A...
Alluvial Fans: Novel Flood Challenge
After disastrous floods hit Cabazon, Calif., engineers faced the challenge of balancing concerns about protecting property and life (by limiting or prohibiting construction) against the...
Dredging and Dredged Material Disposal
Waterborne commerce is a major factor in the economy of many countries. Because waterborne commerce depends on the ability of nations to provide adequate navigation channels to transport...
