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...
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...
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...
Riprap Design by Modified Safety Factor Method
The Safety Factor method for designing riprap is based upon straight forward physics combining rock properties and flow characteristics. M.A. Stevens developed the method by summing the...
Hydraulic Fill Structures
This volume contains 53 papers covering many aspects of hydraulic fill structures with special emphasis on geotechnical issues. The papers present an excellent review of historical development,...
Fly Ash Fills a Valley
The Pennsylvania Department of Transportation (PennDOT) recently placed narly 400,000 tons of fly ash in a structural fill along I-279 near Pittsburgh. The fly ash, believed to be the...
Breakwater Breakthrough�Bold New Breakwaters
A new rubble-mound breakwater design is a departure from the conventional approach detailed in the U.S. Army Corps of Engineers Shore Protection Manual. The new concept, called the berm...
Investigation of Excavatability in the Piedmont
The lateral and vertical variability of rock weathering in the Piedmont presents significant problems in evaluating the probable cost of excavation for deep basements, pipeline, road cuts,...
Design of Drilled Piers in the Atlantic Piedmont
The philosophy and methods of drilled pier foundation design in the Atlantic Piedmont are described. Consideration is also given to the unique characteristics of decomposed metamorphic...
Advanced Identification of Wetlands and Sensitive Aquatic Sites
Region III EPA has implemented advanced identification studies in various locations of its five state area with the majority of the studies focused within the coastal zone. Two such studies...
Mitigation Banking?A Balance of Interests
Mitigation projects are generally conducted on an independent basis. Each time a prospective developer applies for a 404 permit to fill coastal wetlands, he must submit to a lengthy mitigation...
Assessment of Beach Nourishment Methodoliogies
Although artificial beach nourishment has become a common practice for mitigating beach erosion in the U. S. , it lacks clear rationales for achieving optimum benefits. Four recent large-volume...
Restoration of a Construction-Scarred Dune
The rehabilitation and extension of the north and south jetties at the entrance to Siuslaw River required the contractor to stockpile jetty stone in nearby surge piles in order to maintain...
Foundations and Excavations in Decomposed Rock of the Piedmont Province
The five papers in this volume deal with foundations and excavations in the Piedmont Province of the USA. This is a region underlain by very old metamorphic rocks that are overlain by...
Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...
Gradation and Layer Thickness Effects on Riprap
Since riprap has become a costly and in some areas, scarce commodity, proper design maximizing the level of protection with a minimum rock size and layer thickness is an important goal....
Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...
Nuclide Migration from Areal Sources Into a Fracture
The authors show analytic solutions to the problem of hydrogeologic transport of radionuclides released from finite areal sources into a planar fracture. The authors illustrate the solutions...
Lights Out at Caribou
The Caribou powerplant restoration is one of the projects to receive an Outstanding Civil Engineering Achievement Award of Merit. On February 24, 1984 a rock slide on the ridge above the...
Wave Energy Research in Ireland
Measurements taken at several locations off the Irish coast show that the average power intensity available to Ireland well exceeds 20 kW/m. Several projects have been undertaken in an...
