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...
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...
Conglomeratic Shoreface Deposits from the Cretaceous Cardium Formation, Alberta, Canada
Conglomeratic shoreface deposits of the Upper Cretaceous Cardium Formation are well exposed at an outcrop in northwestern Alberta. The conglomerates there compose over 80% of the total...
Gravel Spit Stabilized by Unusual(?) High-Energy Wave Climate in Bay Side, Tierra Del Fuego
A 17 km-long sand and gravel spit grew from the Atlantic coast of Tierra del Fuego in the late Holocene, semi-enclosing a large and deep embayment. Strong westerly winds generate high-energy...
Optimization of Maintenance for Coastal Inlets with Uncertainty
Maintenance dredging costs the nation roughly $400 million per year. Yet, relative to other areas of water resources engineering, little attempt has been made to apply operations research...
Net Late Holocene Emergence Despite Earthquake-Induced Submergence, South-Central Chile
Intertidal deposits show net late Holocene emergence along the Pacific coast near Maullin and Carelmapu, Chile (latitude 41.6?-41.7?S). The maximum amount of net emergence is about 1 m...
Historical Coastal Morphodynamics at St. Marys Entrance and Vicinity, Florida, U.S.A.
St. Marys Entrance is an Atlantic Ocean tidal inlel located on the Florida-Georgia state border. At the end of the nineteenth century rubble-mound jetties were constructed. Large-scale...
Sorting Characteristics of Tidal Inlets
An hypothesis is presented as follows: Littoral processes at a tidal inlet remove a disproportionately higher quantity of fine grain sediment than coarse grain sediment from the littoral...
Regional Sediment Transport in the Coastal Boundary Layer of the Central Alaskan Beaufort Sea
The characteristics of regional sediment transport in the Central Alaskan Beaufort Sea Coastal Ocean are defined by sources, marine sediment dynamics, and areas of net sedimentation. These...
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....
Large-Scale Coastal Evolution of Louisiana's Barrier Islands
The prediction of large-scale coastal change is an extremely important, but distant goal. Here we describe some of our initial efforts in this direction, using historical bathymetric information...
Processes of Shoreline Change Along the Nile Delta Coast of Egypt
A comprehensive program has been underway for more than a decade to collect nearshore data related to erosion problems experienced along the shoreline of the Nile Delta. The data include...
Sea-Cliff Erosion Along the Oregon Coast
Sea-cliff erosion is a problem along the coast of Oregon in that many communities have been built on terraces affected by bluff retreat. There is considerable coast-wide variability in...
Initial Shoreline Response at the Presque Isle Erosion Control Project
Construction of the Presque Isle Shoreline Erosion Control Project in Lake Erie at Erie, PA began October 1989 and consists of fifty-eight offshore segmented breakwaters with beachfill....
Development of an Input Data Set for Shoreline Change Modeling
Procedures and analysis techniques for pre-processing physical data sets in preparation for performing a numerical shoreline change simulation study using the GENESIS model are presented....
Beach Erosion in Japan and Its Classification
Beach erosion in Japan is investigated in a nationwide scale and the causes are classified into six categories. Of six categories the most important factors are 1) obstruction of continuous...
Littoral Environmental Considerations of a Barrier Island in Beach Fill Design: Key Biscayne, Florida
An analysis and understanding of morphodynamic and littoral processes along a coastal shoreline is important in design of a beach fill project. Morphodynamic analysis should include a...
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...
Cross-Shore Sediment Transport Determined by EOF Method
Laboratory and field data of beach profile changes are used to study the cross-shore transport rate. The Empirical Orthogonal Eigenfunction analysis is applied to separate the temporal...
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...
