Innovtive Designs for Low-Level Nuclear Waste Disposal Trenches
Shallow land burial of low-level nuclear wastes presents many problems that are within the scope of civil engineering analysis and design. This paper presents the results of a U. S. Nuclear...
Snow Effects on Pile Design Temperatures
The construction of North Slope aboveground pipelines and gathering lines is generally from snow workpads constructed proximate to existing access roadways. The pile support centerline...
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...
Streamflow Generation from Subalpine Forests
Much of the hydrologic modelling done in the subalpine forest of the central Rockies is based on the Subalpine Water Balance Model. This paper reports on plot studies on the Fraser Experimental...
Snow Management at Ski Areas: Hydrologic Effects
Several types of snow management are practiced at downhill ski areas. Each of these activities has a variety of hydrologic consequences. The extent to which these management practices...
A Systematic Evaluation of Hillslope Subsurface Flow: The Effects of Slope Angle and Soil Parameter Variation
A two-dimensional finite element variably saturated flow model is used in conjunction with an automatic mesh generating scheme to simulate hillslope subsurface flow. Slopes from 2% to...
Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...
Probability of Stability Design of Open Pit Slopes
Uncertainty and risk have always been associated with mining. This is evidenced in the common mining terminology of proven ore, probable ore, and possible ore. From a geotechnical standpoint,...
An Application of Probability to Rock Slope Design
This paper describes the use of probability and statistics in the slope design process. An example is presented of a high rock slope in an open pit mine. This slope is a major concern...
Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...
Soil Nailing Supports Excavation
Excavation for the PPG Headquarters complex in Pittsburgh, Pa. was critical because the site is adjacent to three historically important buildings. Soil nailing, a method of in situ earth...
Critical Load Program
The elastic critical load of a structural frame is a fundamental parameter in assessing its stability. It is an upper bound to the failure load of the frame, in the same way that the Euler...
Innovative Management in a Period of Austerity: The Glamorgan Heritage Cost Experience in the U.K.
Restraint in UK economic growth gave rise to a new countryside management approach which was non-statutory, dependent upon voluntary agreements. In essence the land remains in private...
Regulatory Reform in Alaska: An Oil Industry Perspective
The State of Alaska recently implemented regulatory reform procedures to streamline the permitting process and ease the regulatory burden on the regulated community, as well as the burden...
Implementing Mitigation Policies in San Francisco Bay: A Critique
This paper documents and evaluates 58 permits in San Francisco Bay that required the implementation of wetland restoration projects to fulfil mitigation requirements. The 58 projects are...
Stabilization of Dunes with Flexible Mattresses
Dunes, constantly moving due to influences of sea and wind, are inherently unstable and in many, if not most situations, are best left in their natural state of change. Where there is...
Erosion of the Nile Delta Coast
The construction of the High Aswan Dam has resulted in a total absence of River Nile flow into the Mediterranean, and a corresponding loss of the sediment source for the Delta. However,...
Experimental Study on Sandbag Stability and Runup
Sandbag model tests are performed in a wave flume to examine the effects of berm-type slopes on the stability of sandbags and wave runup as compared to uniform slopes. Measurements of...
Improvement and Construction of Coastal Fishing Grounds in Japan
Development of coastal fishery has become one of the most important issue in the field of food supply. Basically, in order to promote coastal fishery, it is necessary to increase marine...
Project Mixes Oil and Water
The Prudhoe Bay Seawater Treatment Plant was nominated for an OCEA award, for its potential to coax from Alaska's north slope 1 billion barrels of oil which otherwise would...
