Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...
Rock Armouring to Unconventional Breakwaters: The Design Implications for Rock Durability
This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armored slopes. The derivation and use of a suite of engineering tests for...
Reshaping Breakwaters on the Stability of Roundheads and Trunk Erosion in Oblique Waves
The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at The Hydraulics laboratory, Department of Civil Engineering, University of Aalborg....
Hydraulic Performance of Berm Breakwaters
In recent years, the concept of unconventional rubble mound breakwaters, i.e berm breakwaters, has gained much attention among researchers and engineers as an economical method to build...
Application of Computational Model on Berm Breakwater Design
The development of a computational model on dynamic stability is summarized. The model is able to predict profiles of slopes with an arbitrary shape under varying wave conditions. The...
Experimental and Historical Verification of the Performance of Naturlly Armouring Breakwaters
A series of hydraulic model test were carried out to investigate the mechanism by which naturally armoring breakwaters, that is breakwaters in which the initial profile is adjusted into...
The Development of a Design for a Breakwater at Keflavik, Iceland
A breakwater design was developed to be built using local quarried rock and relatively simple construction methods. The design significant wave height was 5.8 and the maximum depth of...
The Design and Construction of a Mass Armoured Breakwater at Hay Point, Australia
The design and construction of a prototype mass armored breakwater is briefly described. The paper also explores the practicality of allowing the progressive interaction of design, physical...
Performance of a Berm Roundhead in the St. George Breakwater System
A new harbor under construction on St. George Island in Alaska's Bering Sea is using the berm breakwater concept for protection from wave attack. Three breakwaters are included...
Implementation and Performance of Berm Breakwater Design at Racine, WI
A large berm-type breakwater has been constructed at the entrance to Racine Harbor, Wisconsin, on the western shore of Lake Michigan. The breakwater is approximately 450 feet long, in...
Berm Type Armor Protection for a Runway Extension at Unalaska, Alaska
A proposed runway extension located on the Aleutian islands was designed to withstand forces of Bering Sea storm generated waves using a unique armor protection concept. The proposed runway...
Unconventional Rubble-Mound Breakwaters?Concerns
A Seminar on Unconventional Rubble-Mound Breakwaters was held in Ottawa, Canada, on the 15th and 16th of September 1987. This paper is an attempt to summarize the general discussion that...
EPA: Siting Permanent Solutions
EPA's SITE (Superfund Innovative Technology Evaluation) program is entering its third year. It is designed to speed up hazardous waste treatment technology. The program helps...
Speaking of RISK
With sensitivity, common sense and preparation, an engineer can explain risk effectively and fairly without alienating the public. Risk communicators should use a standard set of terms...
Lead: Taking it from the Tap
Medical evidence is lowering the definition of a safe concentration of lead. In turn, there has been an effort to reduce lead in drinking water. Solutions are complicated, as many lead...
The North Dakota Atmospheric Resource Program
For over a third of a century regions of North Dakota have conducted cloud seeding operations aimed at hail damage mitigation or rainfall enhancement. Cloud modification has become an...
Tennessee-Tombigbee Waterway and the Environment
An interdisciplinary studies process was instrumental developing the controversial Tennessee-Tombigbee Waterway in an environmentally responsible manner. The paper describes measures incorporated...
Intelligent Construction Machines for Initial Planetary Shelter Fabrication
There have been any number of artists panoramas of initial base and habitat construction on other planetary bodies, notably recently the moon. Most of these conceptual drawings assume...
Antarctic Research and Lunar Exploration: Useful Parallels
Review of the process of scientific exploration in the Antarctic may provide insights into areas that might pose problems to man when further exploration of the lunar surface is begun....
Berm Breakwaters
Unconventional Rubble-Mound Breakwaters
This book presents a state-of-the-art review of the design, analysis, hydraulic model testing, and prototype experience of a new class of coastal structures that produce economical designs...
