Getting Ahead of Snow and Ice
Winter maintenance is not the same anymore. New weather forecasting technologies are permitting snow and ice fighters to better predict when unsafe winter weather conditions will occur....

Snow and Ice Control in Japan and United States
Both Japan and the United States experience severe winter conditions that require major resources and large expenditures for maintaining highways. The maritime climate that prevails in...

Modeling of River Ice Processes for Hydropower Facilities in Cold Regions

A Semi-Discrete Element Approach to the River Ice Breakup and Jamming Process
A semi-discrete element approach was developed to simulate the whole river ice breakup and jamming process. In this approach, ice mass is treated as discrete elements, and the movement...

Coastal Erosion and Sea Level Rise: Residents' and Local Officials' Response
Recent concern about the possibility of the sea rising due to the warming of the atmosphere and the resultant melting of the polar ice caps has prompted attention to the question of how...

Oil Under Ice: Buoyancy Viscous Spreading

Quartzite—A Hard Rock Approach to Rubble Mounds
The quality of stone in rubble mound structures has always been a concern but seems to be more so the past few years. Breakwaters built in the 1920's using granite armour...

Size, Temperature and Rate Effects on the Fracture Toughness of Saline Ice
This paper presents the results of an extensive experimental study performed with the aim of investigating the effects of temperature, size and loading rate on the fracture toughness of...

Computation of Flow in Ice-Covered Dune-Bed Channels
A numerical method for solution of the Reynolds-averaged Navier-Stokes equations is developed to study the flow over sand dunes in two-dimensional channels. The method is applied to calculate...

A Discussion of the Numerical Modeling of Sea Ice Ridging
Pressure ridging, is the failure mechanism of the Arctic pack ice in compression. The large-scale compressive strength of the ice pack is determined by the aggregate of ridge building...

Decision Support System for Multiobjective Service Route Design

Lunar Farside, Mars Polar Cap, and Mercury Polar Cap Neutrino Experiments
Neutrino detection offers unusual Civil Engineering challenges for the inner Solar System, including: outposts and permanent bases on the Moon, a novel development within the polar caps...

In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...

Targeting of AgI in a Utah Winter Orographic Storm
A cooperative research program among the Utah Division of Water Resources, the National Oceanic and Atmospheric Administration, and the Bureau of Reclamation has investigated targeting...

Numerical Integration of Transient Creep Constitutive Equations for Polycrystalline Ice
A numerical time integration algorithm is developed to solved the system of coupled, first-order differential equations characterizing the physically-based constitutive model of Shyam...

Innovative Intake Design for Raritan River

The Effect of Loading Rate on the Bending Strength of Alluvium Reinforced Ice
Traditional building materials are often less than ideal for construction in remote Arctic locations. Their mechanical properties may be degraded in extreme cold, and costs associated...

Processed-Snow Foundation Design at the Summit of the Greenland Ice Cap
The design and construction of a processed-snow foundation berm for an elevated building located at the summit of the Greenland Ice Cap is described. Weather conditions and design provisions...

River Ice Research in China
Hydraulic research in China has concentrated largely on free surface flows, sediment transport, large hydraulic structures, and hydraulic machinery. River ice research activities are expanding...

Evolution of Ice Cover Roughness
The formation of an ice cover on a river results in an increase of stage relative to open water stages at the same discharge. Due to the formation process, especially for freeze-up ice...
