Pricing Armor Rock for Rubble Mound Breakwaters
The pricing of armor rock by breakwater contractors is an inexact exercise. Each breakwater project is so site specific that standard costing methods are difficult to apply. The wide range...
Quarry Techniques for Dimensional Breakwater Stone
On the Texas Gulf Coast, there has evolved a unique design for breakwater and jetty structures. The Galveston District of the U.S. Army Corps of Engineers, the designer of these structures,...
Some Case Histories of Armor Stone Production
The blasting techniques used to produce armor stone, derrick stone, and underlayer stone [one to twenty tons] for the construction of rubblemound breakwalls and the confined Dike Disposal...
Recent Experience With Armor Stone Cracking in the Buffalo District
Accelerated deterioration of large armor stone on the Cleveland East Breakwater, Cleveland, Ohio has resulted in the need for more intensive monitoring of the entire armor stone production...
The 1984 Major Rehab of the Muskegon Harbor, MI South Breakwater: An Extreme Example of Misguided Design of a Stone Structure
It can be inferred from the Shore Protection Manual that the stability of any coastal structure is increased in proportion to the weights of the armorstones. The south breakwater at Muskegon...
RCC for Rehabilitation of Dams in the USA-An Overview
The use of roller-compacted concrete (RCC) has rapidly become a powerful new tool in the USA for engineers involved with the rehabilitation of existing dams. Starting in 1980, RCC has...
Roller Compacted Concrete Tailing Retention Dam
A roller compacted concrete (RCC) dam has been designed for gold tailing impoundment in southeast Alaska. To minimize up front capital costs, the curved gravity dam with multiple outlet...
Santa Cruz Dam Modification
Santa Cruz Dam was the first concrete arch dam in the United States to be modified using an roller compacted concrete (RCC) buttress. Innovative techniques included forming the stepped...

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...
Hampton, New Hampshire: Beach Nourishment Project
An ongoing program of beach nourishment at Hampton Beach, Hampton, New Hampshire is a success and has resulted in long term use of a recreational facility at one of the most popular resorts...
Beach Nourishment with Aragonite and Tuned Structures
The first full-scale use in the United States of imported aragonite sand for beach restoration was undertaken at Fisher Island, Florida, between December 1990 and April 1991. About 20,000...
Sea Defence System at Herne Bay, England
This paper reviews the investigations carried out into the design of the proposed now sea defences fronting the central area of Herne Bay on the North kent coast. The existing defences...
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...
Monitoring of the 1988 Boca Raton Beach Nourishment Project
During July and August of 1988, approximately 843,000 cm of sand was placed along a 2.3-km stretch of beach in Boca Raton, Florida. Post-cosntruction monitoring of the beach nourishment...
Gravel Equilibrium Beach Design for Arresting Shore Erosion at Flathead Lake, Montana
Erosion of the north shore of Flathead Lake, Montana, is caused by summer wind waves generated along a 22-mile fetch. The preferred method for arresting erosion there is a beach composed...
