A Coastal Action Strategy for Southern Africa
The rapidly changing demands and circumstances in southern Africa are offering exciting new challenges in coastal zone management (CZM) and have highlighted the urgent need for effective...
Coastal Dune Blowouts?Dynamics and Management Implications
New approaches to coastal dune management have been advocated recently, including dune grading and dune destabilization. A management concern in the case of destabilization involves the...
Ecological and Geomorphic Impact of the Destruction of a Coastal Sand Dune System in a Sand Spit
Two main effects of the destruction of the coastal dunes at the sand spit of Estero de Punta Banda, (B.C., Mexico) were studied comparing unaltered and altered adjacent zones, The amount...
Restoration of Coastal Dune Systems in Southern California State Parks
Coastal dune systems in southern California possess little of their historical and biological characteristics. If not completely extirpated by development, then the loss of native plants...
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...
A New Panama Canal?
Based upon the 1977 treaty between the United States and Panama and an exchange of diplomatic notes among Panama, Japan and United States, a trinational feasibility study is being conducted...
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...
Moving Muds in the Marine Environment
Fine sediments with cohesive properties abound in the marine environment. We review idealized relationships that are useful in understanding flow behavior of important components of marine...
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...
Infragravity Driven Suspended Sediment Transport in the Swash, Inner and Outer-Surf Zone
Nearbed suspended sediment concentration and velocity measurements from 3 field sites in the mid-outer surf zone (low energy), inner surf zone (high energy) and swash (high energy) are...
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...
Longshore Sand Transport Rate Distributions Measured in Lake Michigan
Cross-shore and vertical distributions of longshore sand transport in the nearshore zone were measured in a field data collection project conducted at Ludington, Michigan, on the east...
