Draft Chapter 2?Planning and Design Guidelines for Small Craft Harbors?Entrance Design and Breakwaters
The paper will present a very preliminary draft of the second chapter of an ASCE manual that is currently being developed. The new manual is entitled Planning and Design Guidelines for...
An Overview: Wetland Restoration, Protection, and Establishment by Beneficially Using Dredged Material
Dredged material has been used beneficially by mankind for many years; in the past two decades it has purposely been used to restore and protect existing wetlands, and to establish new...
Computer Support for Water Quality Management in San Diego Bay
At present, a variety of computer based systems and techniques, including mathematical models, data bases, information management schemes, statistical analysis packages, and graphical...
Engineering Aspects of Wetland Design
Successful wetland enhancement, restoration, or creation projects require integration of desired wetland functions, local hydrologic and soil conditions, and biological requirements into...
Bodkin Island Wetland Restoration Project Design
Bodkin Island in the Chesapeake Bay will be increased by 2 hectares through placement of dredged material to create nesting and brood habitat for black ducks. The enlarged island will...
Savannah International Airport Environmentally Minded Stormwater Master Planning
The proposed Savannah International Airport expansion required a coordinated effort between engineers and environmental scientists to develop a stormwater management plan which would utilize...
Wetland Restoration and Creation Guidelines for Mitigation
The majority of wetland mitigation projects built in the U.S. are failures. Reasons for failure include poor siting, improper design (including inadequate baseline data collection), inadequate...
Assessing the Reliability of the Water Supply to a Closed Basin Wetlands
In many reports, it has been predicted that the loss of the Cheyenne Bottoms as a wetlands area would have an adverse effect on a great deal of the North American migratory shore bird...
Delaware Estuary Nonpoint Source Control Program
Preparation of the Delaware Estuary Management Plan, sponsored by the EPA and the three states of New Jersey, Pennsylvania and Delaware, is part of the national estuaries program. As part...
Creating Wetlands
In the coming decades, many U.S. ports will require expansion and upgrading. Port officials must plan on mitigating the adverse impacts to local habitats. The restoration or creation of...
Experimental Studies for the Port of Bilbao Extension
The Port of Bilbao is the leading port in Spain concerning total traffic volume. It also holds a relevant position in the international context. The Managing Board recently approved an...
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...
The Greening of Greens
Until recently, most consulting engineers thought golf courses were fun to design, good for the portfolio, but not worthy of much serious thought. Environmental issues and competing uses...
A Wetlands Sewage Treatment System for the Community of Teslin
The Village of Teslin, with a population of 450, is located in south-central Yukon, approximately 180 km southeast of Whitehorse. Since 1977, the community has been trucking its sewage...
Wetlands for Acid Mine Drainage Treatment
Wetlands are being constructed on mined lands to treat acid mine drainage. Most of these wetlands remove a substantial amount of iron and sulfate from the water, but manganese removal...
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...
