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...
Longshore Transport of Pebbles: Experimental Estimates of K
Three tracer experiments which provide estimates of the coefficient of proportionality (K) for the longshore transport of pebbles in the CERC equation are reconsidered. The values are...
Late Quaternary Geologic Framework, North-Central Gulf of Mexico
The geologic framework of the north-central Gulf of Mexico shelf is composed of multiple, stacked, delta systems. Shelf and nearshore sedimentary facies were deposited by deltaic progradation,...
Processes Controlling the Retreat of the Isles Dernieres, A Louisiana Barrier-Island Chain
The Isles Dernieres is a low-lying, transgressive barrier-island chain situated about 150 km west of the modern Mississippi delta. Much of the Isles Dernieres consists of highly dissected...
Sand Bypassing at Indian River Inlet, Delaware
To solve a beach erosion problem north of Indian River Inlet, Delaware, the US Army Corps of Engineers Philadelphia District and the State of Delaware have constructed a fixed plant sand...
Late Quaternary (Pre-Holocene) Coastal Systems of New Jersey
The coastline and the area adjacent to the present shoreline of New Jersey has not been explored as intensely as the same region of neighboring states for pre-Holocene high sea level stillstands....
Geomorphology and Sedimentation Patterns of Tidal Inlets: A Review
Tidal inlets are generally formed by either of two mechanisms: storm generated scour channels, and closure of estuarine entrances by growth of sand spits. On depositional, coastal plain...
Regional Beach Sand Volumes of the Pacific Northwest, USA
Eight small littoral cells ranging from 5-60 km in length have been surveyed by beach profiling and seismic refraction to establish active beach sand volumes in the Pacific Northwest region....
Physical Modelling of Pocket Beaches
The design of artificial beach systems is dependent upon the modelling criteria and on the selection of the sand material to be used for nourishment. In order to obtain a stable beach...
Spit Formation in Lake and Bay
A technique of superimposing beach profiles, as a method for analyzing the characteristics and deformation process of a sand spit topography, is proposed, and the morphological changes...
Post-
Hurricane Hugo caused unprecedented damage and extensive beach erosion in South Carolina on 22 September 1989. One week after Hugo, a plan was prepared to push up an emergency dune along...
New Dredging Technology for Inlets and Beaches: Move Sand to the Pump
Conventional dredging for channel maintenance and 'mining' of offshore sand for beach restoration and renourishment 'moves the pump to the sand'....
Monitoring of a Nearshore Disposal Mound at Silver Strand State Park
The migration of an underwater disposal berm constructed in December 1988 approximately six miles south of the entrance to San Diego Bay is investigated. The berm was composed of medium...
Articifical Nourishment at Varadero Beach, Cuba
Following severe storm damage at Varadero Beach during the winter of 1986-87, beach nourishment was carried out at Punta Blanca (17,000 m3), Hotel...
The Use of Aragonite as an Alternate Source of Beach Fill in Southeast Florida
The first full-scale use in the United States of imported aragonite sand for beach restoration was initiated at Fisher Island, Florida, in December, 1990. The project involved placement...
Controls on Sand Resources: Cape Canaveral Area, Florida
Analysis of Holocene stratigraphy and sediments of the continental shelf off Cape Canaveral Florida shows that three basic factors control the quality of sand resources. Antecedent topography...
Complex Principal Component Analysis of Wave-Like Sand Motions
Complex Principal Component Analysis is applied to bathymetric data from the SUPERDUCK experiment at Duck, NC. This approach is shown to describe more of the variation with fewer functions...
Integrated Photogrammetric and Geophysical Monitoring of Shoreline Instability in Littoral Cells in the Pacific Northwest, USA
Several factors have recently focused on the attention of government agencies, academic researchers, and the general public on coastal erosion and beach resource management in the Pacific...
The Santa Cruz Littoral Cell: Difficulties in Quantifying a Coastal Sediment Budget
Beach compartments or littoral cells form the framework for our understanding of the sources, transport, sinks, and storage of sand in the nearshore zone. In general, along the California...
