Development of Storage Demand Relation for Reservoirs?A Probabilistic Approach
This paper presents a practical method for developing storage-demand relation for reservoirs by a probability analysis of the stream flow data. The method was employed by the author for...
Prescriptive Model for Missouri River Reservoir-operation Analysis
The six main-stem reservoirs of the Missouri river system are operated by the Corps of Engineers for flood control, navigation, irrigation, power, water supply, water quality control,...
Modeling of a Large-Scale Water Distribution System
Metropolitan Water District of Southern California (MWD) imports water from the California State Water Project and the Colorado River, providing for supplemental water demands for six...
The Challenge of Kissimmee River Restoration
Between 1962 and 1971, the Kissimmee River in central Florida was channelized by the Corps of Engineers as part of a flood control project. Channelization has resulted in degradation of...
Usefulness of Low-Cost Watershed Monitoring: A Case Study
A one-year monitoring study was conducted for Harford County, Maryland to identify water quality problems and sources in the 98 mi2 Bush River watershed....
A TVD MacCormack Method for Open Water Hydraulics and Transport
The Potential Fate of Particulate Contaminants from the Rehabilitated Ranger Uranium Mine
In the initial period after rehabilitation of the Ranger Uranium Mine most particulate matter released into Magela Creek will be wash load. 10% of the annual deposits on the backwater...
The OCEA Awards of Merit
Submerged rock weirs help tame the Mississippi River, high head pump storage provides power to a community safely and inexpensively, and the world's largest cantilevered hangar...
Waterfall Aeration Works
When they sought an alternative for instream aeration in Chicago's Calumet Waterway System, engineers at the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC)...
Electrokinetic Cleanups
Electrokinetic remediation of contaminated soils is a relatively new research area. Electrokinetic phenomena can be used to create barriers, and move particles, including pollutants such...
Predicting Sediment Loads
Many reservoirs in the U.S. and internationally have experienced unforeseen storage loss when sediment loads exceed those originally predicted during the design stage. This often results...
Cellular Sheet-Pile Floodwall
Williamson, W. Va., flooded 37 times in this century, will soon be guarded by a $41 million, 4000 ft floodwall being built by the U.S. Army Corps of Engineers. A series of 41 circular...
Sending Steel Down the River
Completed last October 1990, the Roosevelt Lake Bridge is now the longest two-lane, single span, steel-arch bridge in North America, spanning 1,080 ft. Also, the longest steel arch bridge...
River Ice Research in China
Hydraulic research in China has concentrated largely on free surface flows, sediment transport, large hydraulic structures, and hydraulic machinery. River ice research activities are expanding...
Evolution of Ice Cover Roughness
The formation of an ice cover on a river results in an increase of stage relative to open water stages at the same discharge. Due to the formation process, especially for freeze-up ice...
Ice Jam Configuration: Second Generation Model
An early model of ice jam configuration in wide, prismatic channels is generalized for applications to natural streams. Test runs are carried out to illustrate model performance and study...
A Conceptual Model for Vertical Frazil Distribution in Turbulent Flows
A conceptual model is presented for the evolution of frazil over depth in a turbulent flow. The net upward migration due to buoyancy of the frazil is opposed by intermittent mixing induced...
Heat Exchange at the Ice/Water Interface on Flowing Water
Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate...
A Two-Dimensional Surface Drift Model for River Ice
A two-dimensional surface drift model for river ice with low ice discharge conditions is presented. The model is applied to the Grass Island Pool area of the Niagara River and compared...
River Ice Cover Cracking for Various Boundary Conditions
The breakup of river ice covers is commonly initiated by the formation of cracks parallel to river banks. These cracks usually result from a change in the water level due to a rapid rising...
