Wave Diffraction Patterns Behind Detached Breakwaters
This paper presents a theoretical model to examine the wave diffraction behind detached breakwaters subjected to regular oblique waves. The method of solution is an eigenfunction expansion...
Development of Offshore Breakwaters for the Marine Multipurpose Zone Project
Under these circumstances, the ministry of construction of Japan has launched the marine multipurpose zone (MMZ) project,and is promoting the effective use of seashores facing the open...
Development of the Long Caisson Type Vertical Breakwater
The width of the caisson of a breakwater is calculated based mainly on the wave force expected to act on the caisson. IN this calculation, the assumed wave force is the peak wave force...
Development of the Double Cylinder Caisson Breakwater
A double cylinder caisson breakwater was recently developed to create a calm sea area in deep and high wave open sea areas. In order to confirm some subjects on design method and construction...
Ecolocy-Conscious Submerged Breakwater
A submerged breakwater makes incident rough waves small when their heights exceed a certain level on the site, though the other waves lower than the level are not so much affected by the...
Laboratory Testing of Stone for Rubble Mound Breakwaters: An Evaluation
The quality of the final stone product hinges on the combination of two factors - rock properties and environmental conditions. The environmental conditions associated with production...
Improving Stone Placement Specifications
Thorough preparation of stone placement specifications can go a long way toward keeping projects on track. But developing well-prepared placement specifications is not easy. It requires...
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...
Durability of Stone for Rubble Mound Breakwaters

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...
An Overview of Segmented Offshore/Headland Breakwater Projects Constructed by the Buffalo District
Since 1977 the Buffalo District has constructed three segmented offshore breakwater projects and currently has one under construction. In addition, the District has recently completed...
Field Monitoring of a Modular Detached Breakwater System
A pair of modular concrete detached breakwaters was installed at a site on the New Jersey shore. This paper describes an eighteen month field monitoring program of the beach response to...
Bay Ridge, Anne Arundel County, Maryland Offshore Breakwater and Beach Fill Design
Construction of the Bay Ridge shoreline protection project was completed in July 1991 and consists of eleven offshore segmented breakwaters with beach fill. The breakwaters, located about...
Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the corps of Engineers' requirement for economic justification. The costs of these measures are much greater than the benefits...
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...
