Coastal Geomorphology and Sand Budgets Applied to Beach Nourishment
It is commonly assumed beach nourishment projects are more successful if applied over long distances of shoreline. Short projects tend to unravel at the ends as the bulge formed by the...
Experience with Beach Fill Equilibration and Recommended Design Guidelines
Well documented engineering procedures suitable for determining design berm dimensions subsequent to profile equilibration appear to be lacking. Failure to properly account for cross-shore...
Short Beach Nourishment Fill Performance on an Irregular Coatline
A review of the beach nourishment fill performance literature reveals that the accepted and proven theories of beach fill performance can be categorized as either one-line models or analytic...
Application of a Beach Plan Evolution Model in Sergipe, Brazil
An offshore breakwater 543 m long located at about 2.4 km from the shore at 10 m of water depth (above chart datums) provides protection to a liquid bulk terminal (Terminal Portuarlo de...
Coastal Processes and Engineering on a Micronesian Fringing Reef
In 1980, portions of the fringing reef flat protecting the village of Tafunsak, Federated States of Micronesia, were dredged to provide fill material for an airport runway access road....
Observation of the Post-Construction Performance of a System of Groins along an Eroding Beach
A system of six groins was constructed along an eroding coast of reversing sediment transport. This paper describes the performance of the groin system in terms of the evolution of the...
Military Techniques for Expedient Repair of Earthquake Damaged Harbor Infrastructure

Santa Barbara Harbor Assessment of Shoaling Frequency
The City of Santa Barbara is addressing the recurring problem of shoaling of its harbor entrance channel. The City relies on income generated from harbor businesses that in turn require...
Scour Hole Development and Stabilization at Shinnecock and Moriches Inlets, New York
A scour hole developed inside the Shinnecock Inlet channel near the tip of the west jetty. Over the years, this hole deepened to about 70 ft below the mean low water level with the average...
Longshore Sediment Transport Rate at Morro Bay, CA
Estimates of sediment transport rate in the vicinity of Morro Bay Harbor are needed as part of an investigation of possible modifications to the existing Federal project. Because the site...
Design Considerations for Small Artificial Islands in Franks Tract, California
Small, artificially-created islands may provide significant recreation and habitat benefits. Costs, however, can also be high. The initial dollar cost of creating an artificial island,...
Concrete for Sealing Voids in Rubble Structures
Permeability of rubble-mound breakwaters and jetties to sand transport and wave transmission results in increased costs for dredging and navigation. Guidance is provided for economically...
Environmental Constraints Associated with Dredging in Southern California
The U.S. Army Corps of Engineers, Los Angeles District, is responsible for the maintenance dredging of twelve harbors along the Southern California coast, ranging from Morro Bay in the...
A New Era In Transportation
Its passage into law was about as smooth as a rush-hour traffic jam, but the surprising thing about the new Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) is that it...
