Laupahoehoe Harbor Planning, Design, & Construction
Laupahoehoe Harbor provides access to the fertile fishing grounds along the northeast or Hamakua coast of the island of Hawaii, Hawaii. The planning, design, and construction of Laupahoehoe...

Inner Harbor Wave Conditions due to Breakwater Overtopping
The results of this study have important application to the design of small boat marinas protected from incident waves by breakwaters that may be overtopped during extreme wave events....

Wave Barriers: An Environmentally Benign Alternative
This paper describes the history and development of the environmental wave barrier and the current planning and design being undertaken for a major expansion of the small boat harbor at...

Design, Construction, and Performance of a Baffled Breakwater
The Spud Point Marina breakwater is located within Bodega Harbor, a protected embayment on the northern California coast. Waves are attenuated by baffle panels hung between support piles....

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,...

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...

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...

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....

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...

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)...

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...

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...

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...

Monitoring of the 1985/86 Beach Nourishment Project at Bar Beach, Victoria Island, Lagos, Nigeria
Bar Beach, Victoria Island, is Nigeria's foremost leisure beach and has been the site of very active erosion following the completion in 1912 of two stone breakwaters perpendicular...
