Major oil and gas projects developed in Santa Barbara County are monitored for compliance with conditions of approval through various enforcement and compliance programs. the Resource...
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...
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...
Sedimentation Processes in Morro Bay, California
A series of field investigations and historical data analyses were conducted to determine historical sedimentation processes in Morro Bay, California. Three sources of sediment were identified:...
Grain-Shape Analysis of Littoral and Shelf Sands, Southern California
Estimation of the exchange rates and determination of transport mechanisms and pathways associated with the onshore-offshore vector is one of the greatest sources of error in sediment...
Observations of a Tidal Inlet on a Shingle Beach
An observation and measurement program was undertaken at Batiquitos Lagoon, San Diego County, California to better understand the paths and rates of shingle movement in the littoral zone....
The Oceanside Experimental Sand Bypass?The Next Step
Following the completion and successful operation of the first phase of the Oceanside Sand Bypass, the next step in the development of the experiment has begun. The Phase I plant is not...
Short-Term Characteristics of Coastal Lagoon Entrances in California
Methods of predicting the frequency of lagoon opening conditions and the cross-sectional area of the inlet channel are reviewed. The potential variation from these empirical relations...
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...
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...
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...
Monitoring of a Nearshore Disposal Mound at Silver Strand State Park
The migration of an underwater disposal berm constructed in December 1988 approximately six miles south of the entrance to San Diego Bay is investigated. The berm was composed of medium...
Sediment Budget at Oceanside, California, Calculated Using a Calibrated Shoreline Change Model
A quantitative sediment budget analysis was made for the shoreline segment extending from 4 miles north to 4 miles south of Oceanside Harbor using a calibrated shoreline change model....
Coastal Process Study on Beacon Shoreline
A sediment budget was developed for the Santa Barbara and Ventura County shoreline in Southern California as part of an overall coastal planning effort. The budget was analyzed primarily...
The Santa Cruz Littoral Cell: Difficulties in Quantifying a Coastal Sediment Budget
Beach compartments or littoral cells form the framework for our understanding of the sources, transport, sinks, and storage of sand in the nearshore zone. In general, along the California...
Impact of Proposed Radon Drinking Water Regulations on Groundwater Systems in California
This summer, the Environmental Protection Agency is expected to propose a maximum contaminant level (MCL) of 300 pCi/l for radon in drinking water. This anticipated MCL, if adopted, will...
Design Considerations for Control of Volatile Organic Compounds at Wastewater Treatment Facilities
New federal and state regulations require publicly owned treatment works (POTW's) to consider emissions of volatile organic compounds (VOC's) as potentially significant...
Continuing Effort to Eliminate Odors at Orange County's Wastewater Treatment Plants
The County Sanitation Districts of Orange County (CSDOC), California own and operate two wastewater treatment plants. Reclamation Plant No. 1, in Fountain Valley, treats approximately...
Redevelopment of Remediated Superfund Sites: Problems with Current Approaches in Providing Long-Term Public Health Protection
The normal primary objective of Superfund site remediation is the control of hazardous chemicals so that they do not represent a significant threat to public health and the environment...
Allocating Water Among Urban Users During Droughts
Beginning in the spring of 1987, California has been besieged by a drought that, as of this writing, has not yet abated. In response to this unprecedented drought, the San Francisco Water...
