A Re-Evaluation of Earthquake Hazards Within the California Coastal Zone: Lessons from the Loma Prieta Earthquake
The 7.1 magnitude Loma Prieta earthquake occurred on October 17, 1989, had a duration of 15 seconds, and took 62 lives. Among the lessons learned from this earthquake with regard to offshore...

An Offshore Seismic Data Network
Response to environmental forces is a major performance consideration in designing offshore oil and gas facilities. Climatic and oceanographic data are available for most offshore sites....

Earthquake Measures for California OCS Platforms
The ability of a platform to withstand earthquakes is one of the primary design factors for platforms on the California outer continental shelf (OCS). This paper discusses (1) the special...

Offshore Oil and Gas Support Facility Siting Study
It has been estimated that the Bodega Basin, which extends offshore of Sonoma County, contains four areas of high potential for oil production, with a total of up tp 195 million barrels...

The Economic Benefits of Hurricane and Storm Damage Reductiohn
The Mobile District of the U.S. Army Corps of Engineers is currently evaluating the feasibility of a hurricane and storm damage reduction project at Panama City Beach, Florida. Under Corps...

The Search for Public Access in New York State
Public access to coastal areas for recreational purposes is a declared policy goal of both Federal and State governments. Accomplishment of this goal involves issues of public versus private...

Geotechnical Failure of Revetments
A calculation method is developed to analyse the stability of a granular subsoil underneath a revetment under wave attack. This method leads to a minimum revetment weight per square meter...

Headland Breakwaters in the Chesapeake Bay
The purpose of this paper is to document and evaluate the use of headland breakwaters in the Chesapeake Bay. Headland breakwater systems have been installed in the Chesapeake Bay since...

Rehabilitation of Vertical Thin-Walled Breakwater
Physical hydraulic model tests were conducted to measure wave transmission and force characteristics of a partial vertical thin-walled breakwater. Tests were run for the breakwater in...

Ocean Mining with Shoreline Protection
This paper describes an existing construction system that permits building large concrete structures directly on the water in low-cost floating formwork with unskilled local labor operating...

Downdrift Effects of Navigation Structures on the California Coast
The impacts of navigation structures on adjacent beaches has been an important aspect of coastal engineering. The modern day birth of coastal engineering in the United States is considered...

Beach and Cliff Erosion Processes at Solana Beach, California, 1984-1990
Observations of back beach elevation changes, profiles and cliff erosion over a 7-year period from 1984-1990 provide a detailed local view of these processes and rates at a typical Southern...

Mitigation for Offshore Development/Fishing Conflicts
Three case studies, WestGold gold dredging offshore Nome, Alaska, Endicott Causeway off Alaska's North Slope, and Platform Irene offshore California, show that project related...

Coastal Erosion Problems in Romania
The paper presents some geomorphological features and erosion problems of the Romanian coast. We also reveal wind and wave climates. General characteristics of the sediments on the entire...

Field Experiment of a Wave Power Extracting Caisson Breakwater
The Ministry of Transport of Japan (MOT) is currently developing a fixed-OWC wave power converter called a wave power extracting caisson. This device can be used as caissons for composite-type...

Coastline Management: A Challenge for Developing Countries
Coastal erosion has been a worldwide problem of primary concern to coastal management and development. To arrest the coastal erosion processes along the coastline of developing countries...

Effects of Sea Level Rise on the California Coast
Although California is thought to be an emerging coastline which would be little affected by a change in sea level, a 5 foot rise over the next 100 years could have a significant impact...

Land-Use Issues Raised by Offshore Oil and Gas Development
While prudent development of offshore energy resources may provide benefit to the nation overall, it invokes several issues for local and regional planning. In particular, petroleum development...

Effective Mitigation of Air Emissions from OCS Sources
Unmitigated, platforms and associated facilities in the OCS typically emit large quantities of air pollution from power generation, drilling, transportation and other activities related...

Field Measurements of the Vertical Structure of Suspended Sediment
The use of acoustic backscatter measurements to determine suspended sediment concentration gives a new view of the instantaneous sediment distribution as a function of height above the...
