Ice Jamming in Upper Niagara River: Processes and Plan of Study
(American Society of Civil Engineers, 1995)This paper is intended to be the first of a series of papers presenting the results of a comprehensive study aimed at evaluating the influences of two large hydropower generation stations on ice transport and jamming in ... -
Numerical Simulation of River Ice Processes
(American Society of Civil Engineers, 1995)This paper presents the formulation of a one-dimensional river-ice simulation model RICEN. The model consists of two major parts: (1) An unsteady flow model for a channel network with ice; and (2) a thermal and ice condition ... -
Simulation and Analysis of Upper Niagara River Ice-Jam Conditions
(American Society of Civil Engineers, 1995)This paper presents the results of model calibration and a parametric study of the ice-jamming processes in the Tonawanda Channel of the upper Niagara River using the one-dimensional river-ice model RICEN. The model is ... -
Overview of Recent Program on Mechanical Properties of Sea Ice
(American Society of Civil Engineers, 1995)This paper describes field and laboratory measurements of the evolving physical and mechanical properties of first-year sea ice through a growth season. The primary objectives were to (1) examine sample size effects on the ... -

Soft, Low-Temperature Water-Distribution Corrosion: Yellowknife, NWT
(American Society of Civil Engineers, 1995)Presented are the results of a water-distribution corrosion study conducted for the City of Yellowknife, Northwest Territories, Canada. Conducted were water-distribution system corrosion tests, the evaluation of corrosion ... -
Hydrostatic Pressure Loading due to Ice Formation in Manholes
(American Society of Civil Engineers, 1994)The magnitude of the hydrostatic pressure that results from the growth of an ice layer at the top of a water‐filled manhole is determined using both analytical (for a thin ice layer) and finite‐element methods (for a thick ... -

Comparison of Methods Used to Create Estimate of Air-Freezing Index
(American Society of Civil Engineers, 1995)A climatography of 100-year return-period air-freezing indexes (AFIs) has been developed to accompany recommendations for the design of frost-protected shallow foundations (FPSFs) in the U.S. residential construction ... -
Effect of Cold Regions Climate on Composite Jacketed Concrete Columns
(American Society of Civil Engineers, 1994)The construction and maintenance of structures subject to subzero (<0°C) temperatures and in cold regions such as in the Arctic poses a variety of problems related to degradation of mechanical properties of exposed materials, ... -
Effect of Preagitation on Freeze‐Thaw‐Conditioned Sludge Dewaterability
(American Society of Civil Engineers, 1994)Sludge dewatering processes are usually preceded by sludge conditioning, which improves the sludge dewaterability. Although sludge conditioning is most commonly achieved by the addition of chemicals, freeze‐thaw ... -
The World is Coming to an End: E. B. Rice Memorial
(American Society of Civil Engineers, 1994)It is necessary to separate fact from fiction and help the general public understand what is happening to the environment, who is causing it, and what they can do to help. Alarmists who misuse science to promote fear, ... -
Breakthrough Loads of Floating Ice Sheets
(American Society of Civil Engineers, 1995)For safe transportation of loads on floating ice sheets, it is important to determine the breakthrough load of an ice sheet. At present, the breakthrough load is estimated using empirical relations developed from the results ... -
Microwave Thawing of Frozen Soils and Gravels
(American Society of Civil Engineers, 1995)Winter conditions in northern climates and permafrost regions make mining and excavation in frozen ground very difficult. Current methods of weakening frozen ground by thawing with combustible materials or electric heaters ... -
Fracture of River Ice Covers by River Waves
(American Society of Civil Engineers, 1995)The stresses induced in ice covers by river waves are investigated as a possible mechanism for causing transverse cracks during breakup. The maximum stress levels that river waves can cause in the ice cover are determined ... -
Bridge‐Pier Location and Ice Conveyance in Curved Channels
(American Society of Civil Engineers, 1994)Channel curvature and the presence of bridge piers, which may effectively subdivide the channel, affect the ice-conveyance ability of curved and sinuous rivers and may favor the initiation of ice jams. Preliminary results ... -
Creep Behavior of Saline Fine‐Grained Frozen Soil
(American Society of Civil Engineers, 1993)Creep tests were conducted on a fine‐grained frozen soil at different salinities ranging from 0 to 20 ppt (parts per thousand), at temperatures between −5°C and −17°C and at two total water contents of around 34% and 52%. ... -
