The Heartbeat of the Artery
One of the most ambitious infrastructure megaprojects in recent memory, Boston's $5 billion Central Artery runs the gamut of civil engineering disciplines. Design, highway,...

Dams Going Safely over the Top
Many older dams can't pass updated design floods without overtopping the embankment crest. Conventional upgrade methods, enlarging spillways or raising crests, are expensive....

Coastal Engineering?The Past!, The Present!, The Future?
The author discusses past and present practices of coastal engineering, and speculates on the diredctions that the profession will take in the future. Also discussed is the question of...

Numerical Beach Profile Modelling for Beachfill Projects
The use of beachfill in addressing coastal erosion problems is becoming increasingly popular. It is often more attractive than the conventional structural approaches for economic, aesthetic...

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...

Design of Protective Dunes at Dam Neck, Virginia
Dunes act as a primary coastal defense against inundation in the Netherlands and the Dutch Government has devoted considerable effort towards development of reliable procedures for the...

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
Logistical support of military forces in the theater of operations during conventional warfare by shipment of large volumes of containerized cargo requires sustained use of strategic port...

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...

57 Years of Coastal Engineering Practice at a Problem Inlet: Indian River Inlet, Delaware
This paper presents a review of Indian River Inlet's behavior in its natural state prior to jetty construction and summarizes the level of understanding of coastal processes and inlet-bay...

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...

South Jetty Scour Hole Stabilization, Ocean City, Maryland
Formation of a scour hole along the inlet side of the South Jetty at Ocean City occurred after jetty construction as a result of ebb tidal flow in the inlet. Analysis of historical bathymetry...

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 of a Mechanical Refuse Barrier
In the summer of 1988, beachgoers flocking to the New Jersey shore for relief from unusually hot, hurried weather were stunned by the grisly spectacle of hospital debris, industrial and...

Wave Forecasting for Construction in Mobile Bay
Wave heights were forecast for day-to-day pipeline construction operations in the Main Pass area of Mobile Bay. A low-cost forecasting procedure was developed using the wave generation...

The Talbert Channel Ocean Outlet Project
The Talbert Channel Ocean Outlet Project consisted of relocating and enlarging the outlet of a relatively narrow, shallow flood control channel in Southern California. Noteworthy aspects...
