A Simulation to Noise Barrier
The problem related to noise barrier is simulated by a still, single frequency, three dimensional sound source located within two parallel screens with rigid back walls. The solution of...
Analytical Solutions for Determining the Location of the Saltwater Interface Below a Strip Barrier Island
Analytical solutions are developed to locate the position of the saltwater-freshwater interface below a barrier island....
Shell Island Evolution
In 1979, Shell Island was overtopped by Hurricane Bob breaching the barrier island with an opening that now has increased to a width of approximately 2.7 kilometers. Saltwater intrusion...
Resilience of Seacoast Bluestem Barrier Island Communities
Natural disturbance is an important force in population and community dynamics and barrier islands are paradigms of disturbance dominated ecosystems. They are formed, shaped, and moved...
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...
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...
Geologic Controls on the Formation and Evolution of Quaternary Coastal Deposits of the Northern Gulf of Mexico
A study of the barrier islands and wetlands in the deltaic plain of Louisiana is presented. Its purpose was to document rapid changes and to learn more about the processes responsible...
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...
Preservation Potential of the Delaware Atlantic Coast Barrier?Backbarrier System
Volumes of Delaware Atlantic barrier and shoreface lithosomes were digitized to evaluate preservation potential during transgression. Erosion during headland retreat of less than 0.5 km...
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....
Geomorphology and Sedimentation Patterns of Tidal Inlets: A Review
Tidal inlets are generally formed by either of two mechanisms: storm generated scour channels, and closure of estuarine entrances by growth of sand spits. On depositional, coastal plain...
Large-Scale Coastal Evolution of Louisiana's Barrier Islands
The prediction of large-scale coastal change is an extremely important, but distant goal. Here we describe some of our initial efforts in this direction, using historical bathymetric information...
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 --...
Institutional Barriers to IVHS Introduction
The introduction and application of Intelligent Vehicle/Highway Systems (IVHS) will help to mitigate the adverse safety, environmental, and economic impacts of traffic congestion on selected...
Role of Waste Packages in the Safety of a High Level Waste Repository in a Deep Geological Formation
The safety of a radioactive waste disposal facility lays on the three following barriers placed between the radioactive materials and the biosphere: the waste package, the engineered barriers,...
Effect of Barrier Beach Breaching on Harbor Dynamics and Storm Surges
This paper presents a summary of the flood insurance study, commissioned by the Federal Emergency Management Agency, to determine the 100-year flood elevation for Chatham, a seacoast town...
Shell Island Restoration
Shell Island is a barrier island along the Louisiana coast that protects back bays and marsh land south of New Orleans. In 1979, the island was breached by a hurricane, exposing the back...
Management of Drumstick Barrier Islands
Three major problem areas exist on these barrier/inlet systems: 1) the updrift inlet which tends to migrate and erode the upland barrier, 2) the narrow, low and sediment-starved downdrift...
Barrier Beach Water Table Management
The solution to the water table elevation within a barrier beach, subject to the assumptions of a homogeneous and isotropic phreatic aquifer, is an ellipse with its long axis oriented...
Barrier Islands: Dynamic Coastal Landforms Requiring Complex Management Decisions
Barrier islands and spits are found along ten to twenty percent of the world's coastline, and are the predominant coastal landforms composing about eighty-five percent of...
