A New Concrete Armor Unit for Breakwaters: The Beta Block
The aim of this paper, is to present a new artificial block for the protection of breakwaters. This armor unit, named BETA, has been designed and tested in the Coasts and Harbors Studies...

Hydraulic Design of Offshore Breakwater in Sergipe, Brazil
A Petrobras (Petroleo Brasileiro S.A.) marine terminal was recently constructed in Sergipe, Brazil (Figure 1). The offshore breakwater was initially designed in a conventional way, but...

Stability of Accropode(R) and Comparison with Parallelepipedic Block
This paper describes the tests which were performed on physical models with irregular waves, to determine the hydraulic stability of the Accropode(R)...

Experimental Research on Groyne Stability Under Very Oblique Wave Action
Most of the experimental research concerning the stability of coastal structures is focused on normal wave incidence. However, many of these structures are subject to waves which run predominantly...

Mobile-Bed Physical Model Tests for the 1992 Olympic Harbour
The undistorted physical model is described which allowed the measurement of the wave induced velocity field along the main breakwater, and also in Somorrostro Beach (Barcelona). The current...

Human Intrusion Scenarios in Nuclear Waste Repository Evaluations
When promulgated, the Environmental Protection Agency (EPA) High Level and Transuranic Waste Standard (40 CFR 191) is expected to require consideration of human intrusion into a nuclear...

Status of WIPP Compliance with EPA 40 CFR 191, December 1990?SAND90-2424C
Sandia National Laboratories is conducting performance assessments for the United States Department of Energy to use in evaluating compliance of the Waste Isolation Pilot Plant with EPA...

Current Developments of the U.S. Great Lakes Shoreline GIS
The Computer Mapping Center of the Detroit District, U.S. Army Corps of Engineers (USACE), in cooperation with the State of Michigan Department of Natural Resources (MDNR), Land and Water...

Sediment Impediment to Boat Launching at Miller Park, City of Avon Lake, Ohio
In 1987 a boat launching facility was constructed at Miller Park, in the City of Avon Lake, Lorain County, Ohio (Figure 1). There have been problems with sediment buildup ever since it...

MORE-A Multi-Objective Ranking Environment for Risk Assessment
This paper explores the development of a computerized decision support system for ranking risks due to environmental concerns. The paper begins with a brief history a comparative risk...

Evolution of Nonlinear Long Waves After Interacting with a Breakwater
Three-dimensional evolution of nonlinear long waves after interacting with a straight thin breakwater is investigated in this paper. The primary interest is to apply a weakly nonlinear...

Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...

Induced Subsidence: Environmental and Legal Implications
Subsidence of coastal areas can be induced by withdrawal of fluids from shallow, unconsolidated horizons beneath the shore zone. In southern California, Huntington Beach, Torrance/Redondo...

Beach Politics?The Importance of Informed, Local Support for Beach Restoration Projects
The increasing utilization of our coastal areas by people and the development attendant to it have resulted in attempts to maintain or stabilize shorelines. In this paper the author emphasizes...

Public Involvement in Coastal Planning?The Long Beach Experience
A land use plan is often the creation of a professional planning staff prepared in response to the direction of public officials. When the City of Long Beach, California, was required...

Case Study: Downdrift Benefits Four Miles and Six Years from a Gravelly Beach Nourishment on Lake Michigan
A Corps of Engineers gravel feeder-beach nourishment at New Buffalo, MI, in late 1980 - early 1981 gave an excellent opportunity to observe the downdrift progress of the gravel. This paper...

Beach Creation by Integrated Shore Protection System
By thinking back to the past efforts of shore protection works against coastal disasters in Japan, the reasons why many sandy beaches have disappeared and why the present shore protection...

Dune Maintenance
Beach nourishment and stabilization may be achieved through the replacement of sand eroded from the dune. A generalized description of the physical processes and the storm protection benefits...
