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...
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...
The River Ice Management (RIM) Program: Developing New Options for Waterways Operations in Winter
Most of the navigable inland waterways of the United States are utilized year-round. In northern portions of this network (mainly parts of the Ohio and Upper Mississippi River basins),...
A Shallow-Draft Icebreaker for the Upper Niagara River
The New York Power Authority (Authority) designed and built a special purpose, shallow-draft icebreaker in 1986 and 1987 for use in the upper Niagara River. The icebreaker is used during...
Radar Monitoring of Ice on the Upper Niagara River
A standard marine radar was used during the winter of 1987-88 to evaluate its potential to monitor the presence and movement of ice in the Grass Island Pool area of the upper Niagara River....
The PowerBarge
Following a brief description of the prefabricated floating PowerBarge concept, the range of application and expected cost and time savings is presented. Environmental benefits are described...
Hydropower in the Upper Ohio River Basin: A Decade of Effort at Risk
The Federal Energy Regulatory Commission (FERC) issued licenses on September 27, 1989 for construction of 16 hydroelectric projects in the Upper Ohio River Basin after up to 8 years of...
Brule Project Spillway Rehabilitation and Expansion
Brule Hydroelectric Project is located near Florence, Wisconsin, on the Brule River about 1.5 miles upstream of its confluence with the Michigamme River. The 80 year old dam developes...
Acid Mine Drainage: An Overview
In the United States, acid mine water adversely affects over 6,500 km (4,000 miles) of rivers and streams. This is, however, a significant improvement over the situation two decades ago....
Ash Disposal at Coal Creek Station
This paper outlines the effort of two utilities to minimize the impact of an 1100 megawatt lignite fired plant's waste stream on the environment. Current regulations, poor...
Vine Street Reborn
Following decades of controversy and a four-year construction effort that threatened to drive both engineers and local motorists crazy, Philadelphia's Vine Street reopened...
Dallas' Flood Caverns
Dallas' North Central Expressway floods during heavy rains, but the dense development that helps create excessive runoff also precludes large detention ponds. The high-quality,...
Formic Acid Requirement for Savannah River Site Defense Waste Processing Facility Melter Feed Preparation (U)
The Westinghouse Savannah River Company (WSRC) will vitrify the high-level radioactive waste into a borosilicate glass wasteform using a slurry-fed, joule-heated melter. Formic acid is...
Removal of Dissolved and Suspended Radionuclides from HWVP Liquid Wastes
It was determined during Preliminary Design of the Hanford Waste Vitrification Plant that certain intermediate process liquid waste streams should be decontaminated in a way that would...
Geographic Engineering Management System
The Memphis District Engineering Division is developing a GIS type data base as part of a Geographic Engineering Management System (GEMS) to assist both the District and the Lower Mississippi...
Use of Computers in the Management of Pecos River Compact
The Pecos River Compact between New Mexico and Texas did not define clearly what New Mexico's delivery obligation was. After a 14-year long litigation in the U.S. Supreme...
Can Negotiations Succeed? The Platte River Case
A study of the processes by which water is allocated in the Platte River system affords an excellent opportunity for studying decision-making processes. The case is not one where only...
Spreadsheet Model Development for the Apalachicola-Chattahoochee-Flint River Basin
In the beginning, water resources personnel scratched out their estimates of how different reservoir operations or system configurations would affect a river using pencil and paper. Many...
