Fractal Crushing
This paper develops an approach to a two-dimensional fragmentation process, in which floating ice floes are driven against each other and break up into smaller floes. It first considers...
Fracture Resistance to Cracking in Ice: Initiation and Growth
The issue of notch sensitivity and brittleness of the test failure is used to forecast the necessary specimen size for a material property initiation toughness; a methodology is developed...
Frazil Ice Problems and Solutions at Hydro-Power Intakes
Active and passive frazil ice effects on hydroelectric plant intake design and operation are described and references are provided. The most frequently encountered problems and the basic...
Manasan Ice Control Structure Rehabilitation & Bypass Designs
Ice control works built on the Burntwood River at Manasan Falls were damaged during the 1985 spring break-up. The ice boom had broken and the lowered pond level indicated that the rockfill...
Australian Intergovernmental Relations and Coastal Zone Policy
Australia has the longest ice-free coastline in the world. The coast, of approximately 37,000 km, transcends a number of biogeographic regions and contains a diversity of marine habitats,...
A Particle Beam Simulation
A two-dimensional beam simulation is developed in which the beam is composed of uniform rectangular blocks. Internal forces in the beam are caused by relative motion between adjoining...
Unusual Spacecraft Materials
For particularly innovative space exploration missions, unusual requirements are levied on the structural components of the spacecraft. In many cases, the preferred solution is the utilization...
Glacial Icemelt in the Wind River Range, Wyoming
The Wind River Range of Wyoming contains the greatest concentration of glaciers in the American Rocky Mountains with two of the larger glaciers being Dinwoody and Gannett Glaciers. This...

Development of a Comprehensive Numerical River Ice Model
An Experimental Study of Oil Spreading in Ice Covered Waters
In this paper the experimental procedure and some preliminary observations from a new series of experiments on the mechanism of oil spreading under fragmented ice are presented. Laboratory...
Flow Distribution in Multiple Channels with Partial Ice Coverage
It is not uncommon for rivers to have multiple channels. The distribution of the total flow to the individual channels depends on their relative hydraulic characteristics of depth, width...
Discrete Element Simulation of River Ice Jams
The discrete element method provides an alternative to traditional analytical and experimental methods for studying river ice transport phenomena. In the discrete element method, the movement...
Under-Ice Plume Dynamics
Creep of Polycrystalline Ice
This paper discusses the extension of creep models for polycrystalline ice to include the effects of a non-monotonic loading history. Attention is focussed on cyclic loading since it is...
Notch Sensitivity of Ice
Few investigators have examined closely the fracture toughness of macrocrystalline and seeded columnar freshwater ice. There has been a wide scatter in the toughness values obtained even...
The Quest for Quality
an Engineer's View on Responsibility and Liability
This proceedings is the product of the 1990 Triennial Conference which is a conference series held every three years, alternating on each side of the Atlantic, originally between the American...
