Probabilistic Description of Ice Forces on an Offshore Arctic Structure
A probabilistic simulation model has been developed to describe the frequency and outcome of multi-year ice floe encounters with a fixed offshore structure located in the Beaufort Sea,...
Selection of Environmental Design Criteria for Arctic Structures
Where data are insufficient for calculation of extremes using probability theory, design criteria may be reasonable defined by combining available data, knowledge of physical processes...
Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Endochronic Constitutive Modeling of Frozen Soil
The static behavior of a permafrost type foundation, for a typical artificial island in the Arctic, is determined using endochronic axisymmetric finite element analysis. Endochronic constants...
Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...
Comparison of Wave Overtopping Prediction to Measurements from Large-Scale Model Tests
A recent large-scale physical model study was sponsored by Arco Alaska, Inc. , to evaluate slope designs for an Arctic offshore oil drilling island. The drilling island will be located...
The Sand Mattress Method of Slope Protection
The sand mattress concept offers promise as an economical alternative to sand bag armor for two distinct applications: (1) slope protection for exploratory islands and/or causeway facilities,...
Asphalt Revetments for Slope Protection in the Arctic
Experience in the Netherlands demonstrates that slope protection of coastal embankments subjected to heavy wave action can be accomplished with lining systems made of mixtures of asphalt...
Validation of the CICE Code for Ice Ride-Up and Ice Ridge Cone Interaction
The discrete element method is capable of analyzing multiple, interacting, deformable, discontinuous or fractured bodies undergoing large motions and rotations. The formulation solves...
Geotechnical Design of Caisson Islands
There are a number of areas where fundamental geotechnical research is required so that non-conservative, rational and safe design of artificial exploration islands can be achieved. Some...
Earth Pressure on Underground Rigid Pipe in a Centrifuge
A series of centrifugal model tests on underground pipes that simulate the actual construction process were carried out to investigate the earth pressure concentration onto the pipe (particularly...
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
MILHY?A Microcomputer Based Hydrologic and Hydraulic Model
MILHY is an interactive, single event, lumped parameter model used to estimate streamflows and water surface profiles. The model was designed for use on basins less than approximately...
Methods for Reliability Analysis of Water Distribution Networks
A detailed review of the literature reveals that there is currently no universally accepted definition or measure of reliability for water distribution networks. The purpose of this paper...
Initial Operation Model for the Central Arizona Project
A microcomputer program for operating uncompleted portions of the Central Arizona Project has been developed. Engineers may use this program daily to assist in scheduling pumping plant...
Local Pressure in Ice-Structure Interactions
Two models for the determination of local pressures during marine ice or iceberg collisions with bottom-founded structures are presented. The first model is a two-dimensional analytical...
Random Vibration Techniques
The paper presents a review of random vibration techniques for analyzing dynamic systems from the perspective of applicability to structural engineering. Problems involving linear or nonlinear,...
Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...
Chaparral Watershed Management: A Systems Approach
The predicted environmental and economic effects of partial chaparral conversion for increased water yield on an experimental watershed in the Prescott National Forest, Arizona, are examined...
Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...
