Sponge Distribution at Arraial do Cabo, SE Brazil
Spatial and temporal distribution of shallow water sponges were studied on southeastern Brazilian rocky coasts by means of qualitative and quantitative samples made by SCUBA diving. Cluster...
Foundations and Breakaway Walls of Small Coastal Buildings in Hurricane Hugo
After Hurricane Hugo a survey of damage to small, coastal buildings was conducted in North and South Carolina. The performance of elevated foundations, breakaway walls and foundation cross...
Geotechnical Failure of Revetments
A calculation method is developed to analyse the stability of a granular subsoil underneath a revetment under wave attack. This method leads to a minimum revetment weight per square meter...
Headland Breakwaters in the Chesapeake Bay
The purpose of this paper is to document and evaluate the use of headland breakwaters in the Chesapeake Bay. Headland breakwater systems have been installed in the Chesapeake Bay since...
Field and Numerical Investigations on Siltation Mechanism in Kumamoto Port
Synthetic investigations on siltation mechanism in Kumamoto Port were carried out by field observations, laboratory tests, and numerical simulations. Natural conditions such as tides,...
Design and Implementation of a Coastal Resource Geographic Information System: Administrative Considerations
A Geographic Information System (GIS) is a data management and information analysis system that allows the capture, synthesis, generation, retrieval, analysis and output of spatial data....
Studies on Meiofauna on Rio de Janeiro Coast, Brazil
This work presents a preliminary survey of the meiofauna groups and the distribution, abundance and temporal changes of the community at Praia Vermelha (Rio de Janeiro, Brazil), in July...
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...
