A Methodology for Coastal Monitoring
This paper sumarizes the routines which will be applied in order to create a methodology that will orient the 2nd phase of the Coastal Management Program in Brasil. The 1st phase, the...
HF Radar Ocean Surface Mapping in Monterey Bay as a Prototype for California Coastal Environmental Monitoring and Governance
A network of coastal HF radars is being established to provide real-time coverage of ocean surface currents, onshore waves, and ultimately wind fields over Monterey Bay. Data products...
A Portable Geographic Information System (GIS) for Coastal Mapping
The combined increases in portable computing power and storage with the availability of new software has enabled the development of a truly portable Geographic Information System (GIS)...
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...
Accurate Shoreline Mapping: Past, Present, and Future
Mapping historical shoreline changes and predicting future shoreline positions requires both accurate and precise analyses of time-dependent fluctuations in water levels and sediment volumes...
Mapping Barrier Island Changes in Louisiana: Techniques, Accuracy, and Results
Changes in shoreline position along Louisiana's rapidly changing barrier coastline were compiled using cartographic data sources and aerial photography from 1855 to 1989. An interactive...
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...
Keys to High-Accuracy Mapping of Shoreline Changes
For many years it has been difficult to overlay maps and aerial photographs with different scales and publication dates using conventional techniques. Large processing errors also made...
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...
Recent Evolution and Potential Causal Mechanisms of Cedar Island, Virginia, 1852-1986
Shoreline mapping was used to reconstruct the historical shoreline evolution of Cedar Island, Virginia in an effort to clarify the debate on barrier island response to sea level rise --...
Cavitation Noise Investigation of a Pump-Turbine
The results from cavitation noise detection measurements on a 35 MW pump-turbine are presented. Detailed information about the cavitation noise is determined including three-dimensional...
