Uncertainty in Models for Environmental Management
In recent years, computer models have become increasingly popular as tools to aid the decision-maker in balancing complex, interacting factors in environmental management and pollution...
An Application of EPA EXTRAN Model to a Flood Management Study in South Florida
In performing the flood management studies, somewhat unique concerns in South Florida are the backwater conditions due to tidal or non-tidal tailwater, flow reversals from project canal...
Drop Test of Dolos Armor Units
Dolosse are concrete armor units used for the cover layer on many breakwaters and jetties. In order to study their complex loads and structural response, a prototype study at Crescent...
Environmental Engineering
The American Society of Civil Engineers annually sponsors a Specialty Conference on Environmental Engineering. The 1987 Conference was held in Orlando, Florida on July 7-9, 1987 with cooperation...
Harbor Revived
In Racine, Wis., officials' plans to turn a defunct commercial harbor into a recreational boaters' paradise have signaled an economic turn-around for a depressed...
Tunnel Saved by Flyash
When inspection early in 1986 showed that Detroit's Northeast Raw Water Tunnel was near collapse at one location, quick action and a unique use of flyash-cement grout or fill...
Coordinating Engineering and Environmental Activities in Hydropower Development
This paper reviews the role of hydropower project personnel, particularly the interaction between project management, engineering, and environmental sciences staff in project planning...
Preventing Fish Mortality at a Large Pumped Storage Plant
A field study program was initiated at the Truman Project to obtain a better understanding of which fish species in the tailrace area would be most susceptible to turbine passage, determine...
Finite Element Analysis of Concrete Armor Units Subject to Wave Impact
Concrete armor units are commonly employed for the protection of shorelines and rubble structures. Their design is primarily based on hydrodynamic stability. However, their structural...
DAPS: An Expert System for Damage Assessment of Protective Structures
An automated reasoning code for the damage assessment of protective structures (DAPS) is being developed within the Air Force. Protective structures in this context will be synonymous...
Precast Roofs for Blast Shelters
A shallow-buried reinforced concrete blast shelter has been constructed and dynamically tested at the U. S. Army Engineer Waterways Experiment Station (WES). Three thicknesses of precast...
An OCEANWHEEL Breakwater
The compression wall and tension spoke structural system (OCEANWHEEL) transfers lateral loads from sea surface to seafloor efficiently. It promises a wide variety of uses beyond the described...
Port Expansion of Eastport, Maine
A recent pier expansion now allows Eastport to provide 40 feet of water at low tide. The pier expansion consists of a concrete-decked steel pipe pile-supported extension to an existing...
Designing Marinas to Mitigate Impacts
The John Wayne Marina was permitted for construction only after certain design features were altered to accomodate major biological and water quality concerns. The moorage basin was relocated...
Perforated Wave Barriers in Small Boat Piers
Perforated breakwaters can be used to reduce the energy and the height of waves entering small boat harbors. By not extending the breakwater to the bottom interference with littoral drift...
Design Concepts for Floating Breakwaters
This paper describes a fundamental approach to the design of a floating breakwater based on the concepts of dynamic analysis of floating bodies. The process results in a relatively simple...
Fisherman's Wharf Breakwater Design and Construction
Fisherman's Wharf Breakwater is a precast prestressed concrete structure presently under construction. It consists of vertical sheet piles braced at the top by batter piles....
Innovative Bulkhead Design: Third Port Project?St. Croix, U.S. Virgin Islands
This paper describes an innovative design making use of a 'master pile' bulkhead to support the waterside rail for travelling container cranes as well as to retain...
Geotechnical Aspects of Waterfront Parks: Case Histories
This paper presents several case histories of waterfront developments, and describes the general approach that the geotechnical consultant should take in the design of these projects....
Innovative Repairs to Steel Sheet Pile Structures
Several unique and many unusual repair techniques have been used to structurally rebuild steel sheet pile walls. An example of a unique repair to a cellular cofferdam utilizing a suspended...
