Success of Dune Restoration After Removal of UXO
The discovery of unexploded ordnance (UXO) at South Beach, a popular recreational beach on Martha's Vineyard island in Massachusetts, necessitated that the area be declared...
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...
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...
Submarine Sand Ridges: Unique Marine Environment and Natural Resources
Submarine sand ridges are large scale depositional sandy bodies on the inner shallow water continental shelves, which are mostly distributed in the macro tide area where the mobile sandy...
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...
Land-Use Issues Raised by Offshore Oil and Gas Development
While prudent development of offshore energy resources may provide benefit to the nation overall, it invokes several issues for local and regional planning. In particular, petroleum development...
Effective Mitigation of Air Emissions from OCS Sources
Unmitigated, platforms and associated facilities in the OCS typically emit large quantities of air pollution from power generation, drilling, transportation and other activities related...
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...
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...
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...
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...
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...
Sand Movement by Wind?Optimising Predictive Power
The aim of the work reported here was to develop a model for the efficient utilisation of standard anemometer data for the prediction of potential sand movement. Accurate aeolian sand...
The Effect of Beach Vegetation on Aeolian Sand Transport
The effect of coastal vegetation on aeolian sand transport is examined through consideration of the governing aerodynamic processes. Local scale processes without the effect of ground...
Functioning of Multi-Row Sand Fences in Forming Foredunes
Foredunes on sandy beaches are best developed through use of a series of fences by which dune height and width can be controlled. In a previous paper, the authors examined the functioning...
Littoral Dune Transport and Morphology Under a Variable Wind Regime
Most of the large dunes are generally produced by a permanent or quasi-permanent winds. Usually winds present strong concentrations of its directional spectrum around its mean direction....
Field Measurements of the Vertical Structure of Suspended Sediment
The use of acoustic backscatter measurements to determine suspended sediment concentration gives a new view of the instantaneous sediment distribution as a function of height above the...
Grain-Shape Analysis of Littoral and Shelf Sands, Southern California
Estimation of the exchange rates and determination of transport mechanisms and pathways associated with the onshore-offshore vector is one of the greatest sources of error in sediment...
Equilibrium Profile of a Beach with Varying Grain Size
The classical concave equilibrium profile shape proposed by Bruun (1954) and Dean (1977) is modified to incorporate a varying grain size across-shore. On most beaches the median grain...
