Environmental Impact on Sepetiba Beach
This paper describes the erosive and sedimentary processes which have been causing damage to the most important beach on Sepetiba Bay in Brazil. Remote sensing techniques and data obtained...
An Update to CoastWatch?NOAA's New Capability for the Coastal Ocean
The National Oceanic and Atmospheric Administration's (NOAA) CoastWatch project was initiated in August 1988 in response to a red tide event off the North Carolina coast....
A New Approach to Ocean Data Management
Ocean Data Management is the collection, storage, analysis and dissemination of a wide variety of physical, chemical, biological and geological data useful for research purposes in the...
Detection of 2-D Nearshore Wave Patterns Using Linear Prediction and SAR Data
Extraction of wave parameters such as wavelength and direction on radar images is normaly done using fast Fourier transforms (FFT) on typical image size of 256 ? 256 which may not be appropriate...
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...
NOAA's Coastal Ocean Database and FOCOS Program
The NOAA Center for Ocean Analysis and Prediction (COAP) was recently formed in Monterey to support collection, distribution, and analysis of marine data for application to coastal ocean...
Numerical Simulation of Alabama's Weeks Bay Estuary
Weeks Bay system models describing water elevation, water circulation, salinity and BOD/DO concentrations are used to investigate two case study scenarios - a dredged ten foot deep boat...
Destruction Caused by Hurricane Hugo: A Timber Resources Damage Assessment in a Coastal Region
Damage assessments of large areas impacted by intense natural storms can be difficult. The purpose of this paper is to investigate the area and amount of damage to pine forests within...
Sediment Yield Location Maps
The West National Technical Center of the Soil Conservation Service is compiling a series of colored sediment yield location maps for the eleven western United States, as well as Alaska...
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...
Moving Muds in the Marine Environment
Fine sediments with cohesive properties abound in the marine environment. We review idealized relationships that are useful in understanding flow behavior of important components of marine...
Alongshore Sediment Transport Rate Distribution
The initial analysis of a new set of experimental data on alongshore sediment transport rate distribution is presented. The distributions were generally found to be bimodal but tended...
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...
Modelling of Cross-Shore Transport
The validity of cross-shore sediment transport modelling in terms of time-averaged velocities and concentrations has been investigated....
Simulation of Bedload Transport of Marine Gravel
Using combined current meter and acoustic measurements, detailed concurrent time series of instantaneous bedload transport rates and flow turbulence have been obtained. The duration, interval...
Bedload Transport Measurement by Imaging of Tracers
A dyed-sand tracer technique is developed for investigation of bedload under laboratory oscillatory flows. Imaging of the tracer with high speed photography allows the creation of time...
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...
