Crack Growth Stability in Ice
The mechanics of stable, time dependent crack growth as a function of geometry and increasing crack length in saline an freshwater columnar ice are examined in this paper. Experimental...
Instability in Granular Chute Flows
Numerical simulations showed that granular flows in a vertical chute can flow as a steady, uniform stream or as an intermittent slug flow. In numerical experiments slugs or grouping of...
Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...
Distant Eyes
A remotely operated vehicle is a miniature unmanned submersible that contains lights, a video camera, other instrumentation, and motor thrusters to move it through the water. The operator,...
In Situ Determination of Smith Soil Model Parameters for Wave Equation Analysis
A methodology for in situ determination of Smith soil model parameters for wave equation analysis is presented. The method uses a small-rod penetration test in conjunction with CAPWAPC...
Penetration Testing for Groundwater Contaminants
Recent advances in penetration testing technology have produced a variety of new penetration devices to measure groundwater conditions. This paper describes two specially designed devices;...
Measurement of Subsurface, Deep Foundation and Slab/Subgrade Conditions with In Situ Seismic, Sonic and Vibration Methods
Case histories are presented to illustrate quality assurance and forensic applications of nondestructive testing and evaluation (NDT&E) methods for in situ investigation of subsurface...
Wave Equation Modelling of the SPT
The stress wave propagation in the Standard Penetration Test (SPT) is described in this paper. It is shown that the SPT is a complex dynamic system and that both force and motion measurements...
Stabilization of Collapsible Alluvial Soil Using Dynamic Compaction
The effectiveness of dynamic compaction for improving collapsible soils was evaluated under field conditions using full scale load tests performed on 1.5 m square footings. Tests were...
Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...
Data Base of Seismic Body Wave Velocities and Geotechnical Properties
A data base of seismic velocities measured in soils and standard geotechnical engineering material properties has been established at the U.S. Army Engineer Waterways Experiment Station...
Meteorological Aspects of Hurricane Hugo
Despite recent improvements in the accuracy of hurricane forecasting at a rate of about one-half to one percent per-year over the past decade, the population growth in coastal mainland...
Performance of Building Resistance to Water, Waves and Erosion
Water damage to buildings due to Hugo was widespread and severe throughout low-lying coastal areas. Flood insurance claim payments have already exceeded $350 million, the largest payout...
Hurricane Hugo vs Critical Lifelines
Hurricane Hugo significantly affected the performance of critical lifelines in South and North Carolina. An overview of the performance of power supply, transportation, communication,...
Hurricane Hugo's Effect on Marina Structures
The author has visited over twenty-five sites along the South Carolina coast and in Puerto Rico to ascertain the effects of Hurricane Hugo on marina facilities. Types of structures evaluated...
Effects of Hurricane Hugo On Water and Wastewater Systems of the Charleston Commissioners of Public Works
Hurricane Hugo had a major impact on the operations of the Charleston Commissioners of Public Works in their effort to provide safe water and wastewater service to their customers. Through...
Lessons Learned by the News Media
The paper summarizes a few things learned from the news media's experience in Hurricane Hugo and which they will try to do differently the next time. These include: simulcasting...
CZMA Consistency Opinions: An Undiscovered Body of Law
The Coastal Zone Management Act allows states to block the issuance of Federal licenses and permits if the permitted activity would be inconsistent with the state's Federally...
Citizen Participation in Regional Planning Efforts
During the past 4 decades the formal role of citizens has become increasingly more apparent under changing legislative mandates. This paper examines citizen participation in developing...
The Dispersion of Ocean Outfall Plumes: Physical and Biological Dynamics
The discharge of municipal wastewater into the coastal ocean through large ocean outfalls is an important component in managing sewage wastes generated by heavily populated urban areas...
