Rediscovery of the Lower Duwamish River Estuary Solutions to Pollution by Point and Nonpoint Source Controls
Beginning in 1960, a series of point-source pollution controls, new sewage interceptors and treatment plant upgrades dramatically improved conventional water quality parameters in the...
Technique for Assessing Estuarine Sediment Pollutants
A technique was developed for the Mississippi Sound whereby all pertinent scientific data could be gathered and be assimilated in a format that would permit sediment pollution to be assessed...
Beach Preservation by Means of Offshore Submerged Mound of Dredged Materials
The beach - sediment - dispersion- offshore or alongshore under the effect of waves and wave induced currents, and inland by wind action may cause a net deficit in sediment budget which...
Nitrification in a Salt Wedge Estuary
Autotrophic nitrifying bacterial activity and numbers were measured in a salt wedge estuary receiving ammonium-rich effluent from a municipal secondary wastewater treatment facility. Instream...
Albemarle-Pamlico Sounds: Issues, Resources, and Management (
The Albemarle-Pamlico Sound complex, located in northeastern North Carolina, is the third largest estuarine complex in North America and the second largest in area in the United States....
Evaluation of Backshore Protection Techniques
The study site is Bethune Beach on the east coast of Florida in southern Volusia County which is experiencing severe and continued erosion problems. This shoreline erosion has become critical...
Nantucket's Broad Creek Opening
On September 20-21, 1961 a severe coastal storm, the remnant of hurricane Esther, formed a 1,200 foot wide, 20 foot deep opening in a barrier beach (Smith's Point at Broad...
Management Responses to Technical Uncertainty
Recent attention to management and regulation of contaminated waste materials has served to heighten awareness of the role of technical uncertainty in regulatory decisionmaking. Two distinct,...
The Impact of Suburbanization on an Urban River
A case study of the impacts of suburbanization on the water quality of an urban river was completed to detail the various impacts of suburbanization on the culture, economy and environment...
Tiered Sediment Quality Evaluations for Dredging Projects
Sediment and water quality are evaluated frequently for U. S. Army Corps of Engineers (CoE) dredging projects to assess potential biological effects, as required for compliance with environmental...
Use of Sediment Bulk Chemistry Data for Dredged Disposal Management in Puget Sound
Although no fully scientific approach for setting and interpreting sediment chemical levels is currently available, an effects-based approach for using bulk chemistry data was evaluated...
Assessment of Beach Nourishment Methodoliogies
Although artificial beach nourishment has become a common practice for mitigating beach erosion in the U. S. , it lacks clear rationales for achieving optimum benefits. Four recent large-volume...
Nearshore Sand Sources for American Samoa: An Alternative to Using Beach Sand
Using a combination of geophysical techniques, in situ observations, and sampling by scuba divers, we investigated along the south shore of Tutuila Island, American Samoa, for nearshore...
Northwest Regional Coastal Study: An Integrated Approach
The Northwest Regional Coastal Study as proposed consists of: (1) identification of problems; (2) inventory of available information; (3) prioritizing problems and study areas; (4) conducting...
Sand Rights, a Legal System to Protect the Shores of the Sea
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...
Monitoring of Coastal Environment for its Management
The paper briefly explains the features of four coastal laboratories established along the southwest coast of India in 1980 and the data gathered by them during 1980-84. Four coastal piers...
Computer Aided Simulation of Fluid-Structure Interaction Problems
The papers included in this book represent state-of-the-art developments in and applications of computer aided simulation of fluid-structure interaction problems in both the terrestrial...
Coastal Sediments
The two-volume Proceedings of Coastal Sediments '87 contain more than 150 full papers delivered at a specialty technical conference of the American Society of Civil Engineers...
Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
Air Chamber Surge Tanks in High Head Hydro Plants
The U. S. Army Corps of Engineers Alaska District considered an air chamber during the design of the 'Crater Lake phase of the Snettisham Project near Juneau, Alaska. A conventional...
