Phased Engineering Development and Multiple Agency Review of Public Safety Issues
Several Santa Barbara County agencies have key engineering review responsibilities for new development. The magnitude of issues raised and the level of engineering review required for...
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...
Forcing Innovation in Air Pollution Control Technology from OCS Development
Air emissions from OCS development projects have been addressed in a three-staged process which involves: engineering to reduce the project's emissions as much as possible;...
Risks of Transporting Petroleum and Other Materials from Offshore Oil and Gas Development
Oil and gas development offshore Santa Barbara County has lead to the preparation and adoption of local policies and mitigation programs specifically addressing the risks associated with...
Monitoring and Mitigating the Socioeconomic Impacts of Coastal Oil and Gas Development
Santa Barbara County has required that all companies engaged in major offshore oil and gas projects participate in a Socioeconomic Monitoring and Mitigation Program (SEMP). Yearly impact...
How to Pay for Coastal Protection: Governmental Approaches
Beach erosion is a major problem in the United States, particularly in California. At the same time, coastal resource protection is becoming increasingly expensive as state and federal...
Accuracy Standards and Development of a National Shoreline Change Data Base
Data associated with mapping shoreline position provides baseline information used by scientists, managers, and planners for quantitative assessment of historical trends and prediction...
Mechanisms of Coastal Cliff Erosion in Ceredigion, West Wales, UK
Investigation of cliff recession along 20km of the West Wales coastline has recognised erosion processes and mechanisms. Mean contemporary recession rates of 13cm/year have been measured...
Seacliff Retreat and Coarse Sediment Yields in Southern California
Seacliffs are erosional slopes. They form when a receding shoreline impinges on coastal terraces, hills, or mountains. Wave-caused erosion at the base of a seacliff controls its long-term...
Numerical Modelling of Lower Lias Rock Failures in the Coastal Cliffs of South Wales
A model has been developed to evaluate slope failure in the interbedded limestone and mudstone Lower Lias series which outcrop for some 30 km in coastal South Wales. Computer simulation...
Model Testing of Shore Protection Schemes at Surfside-Sunset Beach, CA
A 1:75-scale physical hydraulic model was used to investigate the design of proposed structural modifications at Surfside-Sunset Beach, California, with regard to beach erosion at the...
Post-
Hurricane Hugo caused unprecedented damage and extensive beach erosion in South Carolina on 22 September 1989. One week after Hugo, a plan was prepared to push up an emergency dune along...
Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the Corps of Engineers' requirement for economic justification. The costs of these measures...
Initial Shoreline Response at the Presque Isle Erosion Control Project
Construction of the Presque Isle Shoreline Erosion Control Project in Lake Erie at Erie, PA began October 1989 and consists of fifty-eight offshore segmented breakwaters with beachfill....
Rehabilitation of the South Jetty-Ocean City, Maryland
The south jetty at Ocean City, Maryland was rebuilt in 1985 to reduce the frequent shoaling in Ocean City Inlet. The project consists of a new jetty offset 30 feet south of the existing...
The Interaction of Seawalls and Beaches: Four Years of Field Monitoring, Monterey Bay, California
Coastal protection structures have historically been the most common approach to dealing with the problem of shoreline erosion in the United States. Three potential impacts of these structures...
Artificial Headland and Submerged Groyne for a Beach Improvement Project
The design approach that was used to determine the length and elevation of a submerged groyne as well as a system for providing adjustment to the elevation of the submerged groyne is presented....
An Artificial Perched-Gravel Beach as a Shore Protection Structure
Gravel beaches provide the backshore of coastal environments with a protective buffer from wave erosion. A case study is presented of the conceptual design and utility of an artificial...
Beach Stabilization Using Drains?An Experimental Model Study
The use of the drain concept may be an attractive new tool for beach stabilization because it provides an alternative to hard structures and may enhance beach nourishment practices. Two-dimensional...
Design Guidance for Nearshore Berm Construction
Construction of nearshore berms has been gaining acceptance as a cost effective beneficial use of dredged material. This paper presents a systematic methodology for design and evaluation...
