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,...

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;...

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...

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...

Moored Systems for Time Series Observations of Bio-optical and Physical Variability in the Coastal Ocean
Recently, multivariable moored systems (MVMS) have been developed to study the ecology and physics of the upper ocean. Concurrent MVMS measurements provide time series of beam attenuation...

Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...

Regional Monitoring in Southern California
Increasing concern about larger-scale, longer-term, and cumulative environmental effects has outstripped the ability of traditional point-source monitoring programs to provide useful information....

Mixing and Dispersion Processes in the Vicinity of an Ocean Outfall System in Southern California
Ocean wastewater plumes are important for the disposal of municipal wastes in Southern California. These plumes, which are discharged from sanitation systems, can be distinguished in the...

Offshore Oil Terminals?Potential Role in U.S. Petroleum Distribution
The construction of port facilities in deep water, several miles seaward from the nations's coastline, is one of the measures that have been suggested for reducing oil tanker...

Sea Water Environmental Remote Sensing Application on Daya Bay Nuclear Power Station
Owing to its extensive and complete characterization, remote sensing investigations have a special ability to analyze seawater environments and to monitor pollution at coastal nuclear...
