Management of Historic and Non-Historic Submerged Shipwreck Resources in California
The Abandoned Shipwreck Act of 1987 encourages states to establish management programs for historic and non-historic shipwrecks. Conceptually, a management program will consist of a regulatory...
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...
Review of Recent Coastal Research in the Soviet Union
Information about sediment suspension regularities, their distribution in the water column and ways of sediment transport is indispensible for the solution of ecological and sea culture...
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)...
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...
Phased Engineering Development and Multiple Agency Review of Public Safety Issues
Several Santa Barbara County agencies have key engineering review responsibilities for new development. The magnitude of issues raised and the level of engineering review required for...
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...
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...
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...
Neashore Sediment Transport by Slush/Brash Ice in Southern Lake Michigan
Bands of mobile ice are common features in the Great Lakes nearshore zone during the winter months. Samples were collected during December, 1989 to determine the sediment content in the...
The British Beach and Nearshore Dynamics (B-Band) Programme
A large scale collaborative field based research programme (B-BAND), aimed at measuring the small scale processes associated with nearshore dynamics on macro-tidal beaches, is currently...
Monitoring the Response of the Inter-Tidal Beach Profile to Tidal and Wave Forcing
The need for sets of beach profile and wave data of one year duration, sampled at sub-weekly intervals, is well recognised in the literature. Some of the initial data from a macro-tidal...
Effect of the Earth Rotation on Tide Induced Sediment Transport
Semi-enclosed seas are generally composed of narrow straits and wide basins, forming a strait-basin system. In the strait-basin system where tidal current prevails, the strong tidal current...
Modelling of Cross-Shore Transport
The validity of cross-shore sediment transport modelling in terms of time-averaged velocities and concentrations has been investigated....
Onshore/Offshore Sediment Transport and Morphological Modelling of Coastal Profiles
This paper presents a deterministic model for the morphological evolution of a coastal profile for direct incoming waves. The model contains description of waves across the coastal zone,...
Cross-Shore Sediment Transport Under Irregular Waves in Surf Zones
A numerical model is proposed to predict the free surface elevation and depth-averaged velocity in the surf and swash zones for normally incident random waves. Comparison of the numerical...
Bedload Transport Under Low Frequency Waves
The concept of a bedload spectrum, showing the distribution of energy with frequency in the bedload process, is proposed. The bedload process is thus analysed in the frequency rather than...
The Effect of Beach Slope on Oscillatory Flow Bedload Transport
The data for five laboratory sloping bed bedload sediment transport experiments are presented. Each consists of a series of half cycle transport rate measurements using the same waveform...
