Relationships between Shear Wave Velocity and Depth of Overburden
Relationships between in-situ shear wave velocity and depth of overburden have been derived for various Quaternary age soils encountered primarily in Southern California. The geotechnical...
Case Histories: Evaluation of Drilled Pier Integrity by the Stress Wave Propagation Method
The Stress Wave Propagation Method (SWPM) was used to nondestructively investigate the integrity of straight-shaft drilled pier foundations at two sites in the Denver, Colorado area. Drilled...
Simulation of Rock Fracture with the 3-D SHALE Code
The 3-D SHALE code simulates the propagation of stress waves and the occurrence of fracture in brittle solids. The physical models and numerical methods in this code are similar to those...
Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...
Detection of Leakage Through Subsurface Barriers Using Guided Acoustic Waves
The primary method for preventing hazardous liquid and leachates from entering the groundwater is the use of a physical barrier. These barriers are susceptible to a number of mechanisms...
Health Effects Evaluation?Ocean Disposal of Sludge
Court rulings have recently allowed the ocean disposal of municipal wastewater sludge in certain cases. This paper describes a methodology which was developed to determine acceptable loadings...
Coast of California Storm and Tidal Waves Study: A Regional Coastal Zone Monitoring Program
An integral aspect of the Coast of California Storm and Tidal Waves Study (CCSTWS) was the implementation of a four year comprehensive regional coastal zone monitoring program in 1983....
After Action Report 1983 California Coastal Storms
The winter of 1982-1983 saw some dramatic changes in the worldwide weather patterns that have been attributed to the anomaly known as El Nino. During that winter California was attacked...
The Analysis of the Environmental Impact
Oil serves mankind. Winning such a valuable and necessary energy resource demands for stringent rules. It is not the oil which threatens the environment on earth, but the negligence of...
Coastal Management Problems in the United Kingdom
Five case-studies from the East coast of England illustrate some of the obstacles facing more enlightened coastal management in the United Kingdom. All the examples demonstrate unsatisfactory...
Prior Planning for Post-Hurricane Reconstruction
Planning for hurricane emergencies has focused upon the period immediately before and after the storm's arrival, emphasizing evacuation and disaster relief. Mitigation of...
Coastal Wetland Restoration ? Developers Challenge
National policy asks protection of wetlands regardless of condition and with no provision to return them to functional condition. Neither state nor federal agencies budget for capital...
Survival of Ocean Life: The Critical Balance
Several major problem areas in ocean management are in need of immediate and stringent address. Excessive erosion and sedimentation, stems from man's inadequacies in land...
Contained Dredged Material for Open Ocean Disposal
An intensive series of investigations were conducted on the sediments deposited in Craney Island, a 1012 hectare contained disposal facility in the Port of Hampton Roads, VA. Geographic...
Dredge Material Evaluation Through Harbor Characterization in New England
The New England Division (NED) of the Corps has recently developed a broad based methodology for simultaneously evaluating dredging projects that are in close proximity and which would...
Ocean Dumping at the Philadelphia Site; A Case Study
This study reviews the results of eleven years of investigation of the impact of ocean disposal of sewage sludge at the Philadelphia dumpsite. The site, located on the continental shelf...
Radioactivity in the Ocean: Laws and Biological Effects
This paper summarizes the literature on U. S. laws and international agreements, experimental and monitoring data, and ongoing studies to provide background information for environmental...
Moving Society's Wastes Through the Coastal Zone
This paper considers the use of incinerator ships for the destruction of liquid hazardous waste. Needless to say, such a system requires movement of wastes through the coastal zone. This...
Use of Remote Sensing to Assess Estuarine Habitats
Estuaries and lagoons are dominant features in Florida. They are among the most productive ecosystems on Earth and provide food and shelter for a large and diverse group of living resources....
Investigations of Day-Night Distributional Changes of Striped Bass in Hudson River Interpier Areas
As part of a Hudson River fisheries study, investigations were made in an attempt to assess whether onshore-offshore movements could change the number of juvenile striped bass using interpier...
