Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
The Assessment of Armourstone for Shoreline Protection
To protect shorelines from erosion, Ontario Hydro is using armourstone at various Generating Stations along the perimeter of the Great Lakes. Armourstone is carefully evaluated prior to...
Service Records of Chicago District Breakwater Stone and How These Relate to Test Results
Breakwater stone production is limited to areas with geologic outcrops capable of producing large rocks. The most reliable breakwater stone is that which exhibits the highest degree of...
Quartzite?A Hard Rock Approach to Rubble Mounds
The quality of stone in rubble mound structures has always been a concern but seems to be more so the past few years. Breakwaters built in the 1920's using granite armour...
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,...
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...

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...
Mitigation of Harbor Caused Shore Erosion with Beach Nourishment Delayed Mitigation, St. Joseph Harbor, MI
St. Joseph Harbor MI. was the first Corps of Engineers Section 111 erosion-mitigation project to be built. Between 1 Jun 76 and 5 Aug 85, about 1,067,000 cy of fine sand was placed in...
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...
An Overview of Segmented Offshore/Headland Breakwater Projects Constructed by the Buffalo District
