Citizen Participation in Regional Planning Efforts
During the past 4 decades the formal role of citizens has become increasingly more apparent under changing legislative mandates. This paper examines citizen participation in developing...

Aerial Videotape Mapping of Coastal Geomorphic Changes
An aerial geomorphic mapping system was developed to examine the spatial and temporal variability in the coastal geomorphology of Louisiana. Between 1984 and 1990 eleven sequential annual...

Sonar Mapping of Giant Kelp Density and Distribution
The methods of estimating the density and distribution of giant kelp, Macrocystic pyrifera, and substrate type, using side-scanning and down-looking sonar are described. These techniques...

A recent investigation of the mass movement modified cliffs along the Bristol Channel coastline has been achieved by utilising ground survey data, historical and contemporary cartographic...

The Exxon Valdez Oil Spill: Update on Persistence and State of Alaska Activities
The Exxon Valdez incident of 24 March 1989 caused the oiling of over 1,100 miles of Alaskan coastline and over 11,000 square miles of coastal waters. The State responded immediately to...

Shear Velocity and Eolian Sand Transport on a Barrier Island
Nearly 18 months of simultaneous measurements of atmospheric shear velocity, sand transport quantity, and beach erosion survey were made to investigate the rate of eolian sand transport...

Observation of Suspended Sediments in Mobile Bay, Alabama from Satellite
As part of a comprehensive geologic study of coastal Alabama and Mississippi, the U.S. Geological Survey is investigating coastal sediment transport in Mobile Bay and the adjacent shelf....

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...

Late Quaternary (Pre-Holocene) Coastal Systems of New Jersey
The coastline and the area adjacent to the present shoreline of New Jersey has not been explored as intensely as the same region of neighboring states for pre-Holocene high sea level stillstands....

Processes of Sediment Transport and Ebb Tidal Delta Development at a Jettied Inlet
This paper deals with the development of the ebb tidal delta following the extension of jetties at a tidal river entrance. The growth rate and morphological change are discussed using...

Regional Beach Sand Volumes of the Pacific Northwest, USA
Eight small littoral cells ranging from 5-60 km in length have been surveyed by beach profiling and seismic refraction to establish active beach sand volumes in the Pacific Northwest region....

Monitoring of a Nearshore Disposal Mound at Silver Strand State Park
The migration of an underwater disposal berm constructed in December 1988 approximately six miles south of the entrance to San Diego Bay is investigated. The berm was composed of medium...

Integrated Photogrammetric and Geophysical Monitoring of Shoreline Instability in Littoral Cells in the Pacific Northwest, USA
Several factors have recently focused on the attention of government agencies, academic researchers, and the general public on coastal erosion and beach resource management in the Pacific...

Topographic Responses to the Construction of Large Port Structures on Oarai Coast
Large offshore breakwater and groins have been constructed at Oarai Port, Japan. As a result, the coast experienced significant topographic changes. In this paper, the responses of the...
