Sediments and Quaternary Study of the Coastal Lagoon of Unare (Venezuela)
The coastal Lagoon of Unare is located in the N.E. of Venezuela (62? 12' - 65? 25' W/10? 04' - 10? 08' N), it is 26 km long and 6 km...

3-D Modelling of Suspended Sediment Transport
A three-dimensional finite difference model has been developed for the numerical simulation of the physical process of horizontal and vertical convection, horizontal and vertical diffusion...

Shore Protection Conflicting Objectives in Decision Making
Shore protection, in an era of rising sea levels and declining sediment budgets, is emerging as a priority item in coastal management. Yet to the traditional conflict between man and nature...

Environmental Impact on Sepetiba Beach
This paper describes the erosive and sedimentary processes which have been causing damage to the most important beach on Sepetiba Bay in Brazil. Remote sensing techniques and data obtained...

Coastal Erosion in Ghana: Causes, Patterns, Research Needs and Possible Solutions
The pattern of coastal erosion in Ghana is described. The causes for spatial differences in the erosional rates on the shoreline are identified as coming from a combination of natural...

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...

Environmental Impact of a Power Plant: A Case From a Coastal Area in Venezuela
These are the results of a eight years study in which the ecological effects of Planta Centro power plant were assessed. Many aspects were included in this study, but we concentrate here...

Mercury-Contaminated Sludge Treatment by Dredging in Minamata Bay
To eradicate Minamata disease, caused by sewage containing methyl mercury accumulating in fish and shell-fish through the food cycle, a large-scale sediment disposal project was conducted...

Beach Change Magnitudes in Relation to Dynamic Phases on Dissipative Coasts
Dissipative-prone beaches are statistically and aethestically the most significant on open sea sandy coasts. These beaches owe their widespread occurrence to their temporal stability....

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...

Evidence for Eustatic Influence on Cenozoic Sedimentation of Coastal Washington and Oregon
Comparison of the absolute age boundaries of the West Coast biozonation with the Cenozoic global cycle chart indicates that 12 of the 15 zonal boundaries coincide with regressive sequence...

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...

Monitoring the Physical Evolution of Tidal Wetland Restoration Projects
Increased knowledge of the ecology, biology, and physical processes of wetland environments in the last several decades has improved the awareness of the critical role these environments...

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...

Review Notes on Cohesive Sediment Erosion
Comments are made on issues related to surface and mass erosion phenomena associated with cohesive sediment beds, and the entrainment of fluid mud. The rate process theory is recapped...

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...
