Saline Intrusion in Marine Effluent Outfalls
The paper presents an experimental investigation of saline intrusion in long sea outfalls. This intrusion is caused by the influx of sea water that may occur during periods of low discharge,...
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...
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...
A Childrens' Oil Spill Preparedness Education Program
Following the Exxon Valdez incident, the Clean Seas oil spill cooperative received numerous requests for additional information on oil spill response procedures from local educational...
NDBC's Observations in the Coastal Zone
The National Data Buoy Center (NDBC) has been collecting data from coastal buoys since 1979. Measurements, taken each hour, include wind direction, wind speed, significant wave height,...
Coordinated Management of Coastal Waters in the New York-New Jersey-Connecticut Region
The U.S. Environmental Protection Agency Region II is currently funding three major water quality planning efforts for the coastal waters in the New York-New Jersey-Connecticut region....
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...
U.S. Environmental Protection Agency's Region IX Near Coastal Waters Program
The Environmental Protection Agency's (EPA's) Near Coastal Water Program began in 1985 when former Administrator Lee Thomas requested the development of the Near...
An Overview of Chemical Contaminants Throughout the Coastal and Estuarine United States
Informed decisions on the use and management of the nation's resources requires convenient access to current and reliable information. Since 1984, the National Oceanic and...
Evaluation of the National Coastal Zone Management Program
The Federal Coastal Zone Management Act has gone through nearly two decades of evolution since it was first enacted in 1972. In that time 29 states and territories have chosen to participate...
Basic Physical Models in Sediment Transport
Basic particle dynamics and cellular automata micromodels of clastic sediments are described and applications are illustrated in the areas of aeolian saltation, bedload transport, size...
Mechanics of Cohesionless Sediment Transport in Coastal Waters
Conceptual mechanics-based models for sediment transport processes in steady and unsteady turbulent boundary layer flows are derived and discussed. To the extent possible the predictions...
Infragravity Waves, Longshore Currents, and Linear Sand Bar Formation
A new hypothesis regarding the role of infragravity waves in controlling the formation and offshore migration of linear (2-dimensional) sand bars is presented. The hypothesis is dependent...
Long Wave Effects in Laboratory Studies of Cross-Shore Transport
A movable bed physical model study was conducted to investigate the influence of trapped low frequency energy on wave transformation and beach profile evolution. Using identical drive...
Sediment Transport in the Swash Due to Obliquely Incident Wind-Waves Modulated by Infragravity Waves
Swash is described by obliquely incident wind-waves superposed on, and interacting with, long standing waves. The wind waves of the inner surf zone are modulated in amplitude, wavenumber...
Effect of Long Waves to Local Sediment Transport Rate
When irregular waves travel to the shoreline, long wave component becomes important in the surf zone. In the surf zone, sands are transported by both wave motion and turbulence due to...
Critical Examination of Longshore Transport Rate Magnitude
Inconsistencies in the field data and predictions of longshore sediment transport (LST) rates associated with the CERC and Bagnold formulae are discussed. Practical errors in direct application...
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...
Relationship Between Longshore and Cross-Shore Transport
Radiation stress principles are shown to control both longshore and cross-shore wave induced stresses which in turn determine the major processes controlling sediment transport. Recent...
A Calibrated Longshore Transport Model for Richards Bay
In order to plan maintenance dredging at the Port of Richards Bay, different studies were carried out. These were to determine the extreme dredging rates required in the long term and...
