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...
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...
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...
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...
Quantifying Mud Exchange Between the Eastern Scheldt Tidal Basin and the North Sea
Net transport of sediment < 53 ?m through the mouth of the Eastern Scheldt has been quantified. Combination of data on spatial and temporal variability shows that incertainties...
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...
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...
Morphodynamics of the Isles Dernieres Barrier Shoreline, Louisiana: 1984?1989
An aerial videotape mapping system was used to monitor spatial and temporal variability of the coastal morphology along the Isles Dernieres barrier shoreline. Between 1984 and 1989, nine...
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...
Beach Profile Response to Hurricane Hugo
The impact of hurricane Hugo on the beaches of South Carolina is examined by comparing beach survey data collected during the spring and summer of 1989 with post-storm survey data collected...
Beach Profile Modelling: Flume Data Comparisons and Sensitivity Tests
Some results from a deterministic computational model of beach and nearshore profile development are presented in this paper. Comparisons are made with prototype-scale flume measurements...
