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...

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...
