Design and Construction of Shinnecock Inlet, New York
Shinnecock Inlet is the easternmost of six coastal inlet which bracket the barrier island on the south shore of Long Island, New York. Through recent history, Shinnecock Inlet has exhibited...
Scour Hole Development and Stabilization at Shinnecock and Moriches Inlets, New York
A scour hole developed inside the Shinnecock Inlet channel near the tip of the west jetty. Over the years, this hole deepened to about 70 ft below the mean low water level with the average...
South Jetty Scour Hole Stabilization, Ocean City, Maryland
Formation of a scour hole along the inlet side of the South Jetty at Ocean City occurred after jetty construction as a result of ebb tidal flow in the inlet. Analysis of historical bathymetry...
Alternative Study for the Breakwater and Fishing Pier Rehabilitation at Playland Park, Rye, New York
An alternative study was conducted to determine that existing condition of a deteriorated timber pier and a rubblemound breakwater, and to develop alternative rehabilitation plans leading...
Development of Detached Breakwater Design Criteria Using a Shoreline Response Model
An evaluation of beach response to detached breakwaters was conducted using the numerical shoreline response model GENESIS. Functional design parameters such as structure length, gap distance,...
Application of a Dolos Structural Design Procedure
Dolos concrete armor units are widely used to protect coastal structures. New developments in armor unit strength design permit the armor unit designer to optimize the dolos parameters...
Concrete for Sealing Voids in Rubble Structures
Permeability of rubble-mound breakwaters and jetties to sand transport and wave transmission results in increased costs for dredging and navigation. Guidance is provided for economically...
Application of Extremely Low Altitude Photogrammetry for Monitoring Coastal Structures
Extremely low altitude mapping photography exposed from a helicopter is showing considerable promise in providing another method of extending the many benefits of photogrammetric data...
Value Engineering in Coastal Design
A formal procedure of value engineering can be applied to coastal design to refine a design and reduce the construction costs. Despite the relatively simple technology and materials used...
Sandbridge Virginia Oceanfront Seawall Arbitration Hearing: Some Lessons Learned for Coastal Engineers
A group of beach property homeowners claimed that their new oceanfront seawall was defective in design. A beefed-up design cost about $1.3 million more and they sought this amount from...
VOCs: The New Effluent
The Clean Air Act of 1990, in addition to many state and local regulations, has officials of publicly-owned treatment works (POTWs) shifting their focus, and funds, to air toxic emissions...
Flexible Porous Breakwater
This is a theoretical study of the reflection and transmission of linear waves by a flexible, porous and thin beam-like breakwater held fixed in the sea bed. The breakwater is idealized...
Screen Breakwaters
The diffraction of water waves by an offshore breakwater consisting of an infinite row of equally-spaced vertical screens is investigated theoretically. The reflected and transmitted wave...
Wave Induced Vortex Near Seashore
The vortex motion behind submerged breakwaters in the nearshore region is studied. The RCPWAVE model (Ebersole et al., 1986) is used to calculate the wave field and thus the radiator stresses...
Full Scale Application of Active Bracing Systems
A full scale active bracing system has been installed in a structure in Tokyo, Japan. The practical problems associated with the implementation of this system, and the corresponding solutions...
Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...
Impact of Breakwater Removal on Hydrodynamics and Water Quality in Flushing Bay, New York
Hydrodynamic and water quality models were used to simulate the potential effect of removing a breakwater to increase flushing and improve water quality in Flushing Bay, New York City....
Incorporating Corrosion in Reliability-Based Design of Anchored Bulkheads
Corrosion of steel is an important factor in the design of marine structures. A reliability analysis of anchored bulkheads showed that corrosion changes the critical failure mode from...
Deep Water Container Wharf & Crane Foundation
A deep water anchored steel bulkhead and a parallel-independent low-profile, pile supported crane rail foundation with special stowage areas are discussed from soils investigation, through...
Riprap Design in Marine Terminals
Navigation vessels in otherwise quiescent waterways sometimes generate forces that require stabilization of the bed or banks. Since riprap is an accepted and dependable means to armor...
