Stabilization of West Coast Sand Dunes
Control of dune activity and the introduction of European beachgrass have generated far-reaching effects on the West Coast landscape. Between 1900 and 1935, a series of small sand stabilization...
Foredune Management on a Developed Shoreline: Nedonna Beach, Oregon
Nedonna Beach and Rockaway Beach are adjoining oceanfront communities with foredunes that were developed before state policies went into effect. The foredunes in these two communities...
Beach Replenishment: The National Solution?
The records of more than 90 replenished beaches and more than 200 sand-pumping operations on East Coast barrier island shorelines, while fragmentary, reveal a wide range of experiences,...
Parameters Controlling the Success of Dune Revegetation at King Salmon, California
An eroded 9. 3 ha (23 acre) sand spit was restored through jetty construction and fill (using dredge spoils) by the Corps of Engineers at King Salmon on Humboldt Bay, California. An experimental...
Erosion and ErosionControl of a Silt-Muddy Beach
In China, many large and middle rivers such as Yellow River, Yangtze River, Pearl River, Liaohe River carry a large amount of fine sand into the sea, this results in extensive silt-muddy...
Evaluation of Sand-Filled Containers for Beach Erosion Control: an Update of the Technology
The use of large, sand-filled geotextile containers for coastal erosion protection has increased along Florida's ocean shorelines over the past five years. Technological advances...
Evaluation of Backshore Protection Techniques
The study site is Bethune Beach on the east coast of Florida in southern Volusia County which is experiencing severe and continued erosion problems. This shoreline erosion has become critical...
Nantucket's Broad Creek Opening
On September 20-21, 1961 a severe coastal storm, the remnant of hurricane Esther, formed a 1,200 foot wide, 20 foot deep opening in a barrier beach (Smith's Point at Broad...
Nearshore Sand Sources for American Samoa: An Alternative to Using Beach Sand
Using a combination of geophysical techniques, in situ observations, and sampling by scuba divers, we investigated along the south shore of Tutuila Island, American Samoa, for nearshore...
Sand Rights, a Legal System to Protect the Shores of the Sea
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...
Sea Level Change and Coastal Geomorphology of Padre Island, Mexico
Extending some 244 km from the Rio Bravo (Rio Grande) on the north to the mouth of the Rio Soto la Marina (at La Pesca) on the south, Padre Island, Mexico is comprised locally of several...
Canal Automation Using the Electronic Filter Level Offset (EL-FLO) Method
Beginning in 1969, the Bureau of Reclamation began testing and refining an electronic filter level offset (EL-FLO) control system for canal automation. The control system uses a proportional...
A Tidal Hydraulic Model of the C&D Canal
The Kalman filter combined with one-dimensional shallow water wave equation is applied to describe the tidal hydraulic behavior of the Chesapeake Bay and Delaware bay canal. This model...
Update: Fluidization for Tidal Channel Maintenance
Flow emanating from perforations in a pipe under a non-cohesive media, such as sand in the coastal environment, can fluidize the overlying media. The fluidized sand can be readily moved...
Modeling Sediment Yield Affected by In-Stream Sand Mining
Sediment yield refers to the amount of sediment having passed a given river section for a specified duration. While sediment will be stored in the borrow pit, it will also be depleted...
Evaluation of Sand as a Modeling Material Using Vellinga's Guidance
An experimental series of flume tests were conducted using three sizes of sand as modeling sediment in order to evaluate the effect of sediment grain size and the range of validity of...
Simulation Algorithms for Offshore Structures
A rational procedure for characterization of water depths for a random sea state is developed, in context with linearized wave theory. The importance of using the expressions for 'intermediate...
Blasting Densifies Sand
Constructing the Jebba Dam on Nigeria's Niger River required in-place densification of large volumes of loose sand to record depths of up to 131 ft. Vibrocompaction was used...
Determining Sand Strength by Cone Penetrometer
Evaluation has been made of several theories and methods for deducing sand strength from cone resistance. Bearing capacity theories, cavity expansion theory, and empirical methods have...
In Situ Testing of Calcareous Sand?Campos Basin
Sampling and in situ testing were used to investigate soil conditions for the installation of offshore platforms at the Campos Basin, Brazil. At these sites calcareous sand formations...
