Field Application of a Numerical Model of Beach Topography Change
Discussion was made, on the basis of field data, on the applicability of the formula for local rate of sediment transport due to combined action of waves and currents presented by Watanabe...

Mathematical Model of Groyned Shingle Beaches
The paper describes the development of a mathematical model designed to be used by coastal engineers to study the effects of groynes on shingle beaches. The main task of the model is to...

Beach Erosion in Japan and Its Classification
Beach erosion in Japan is investigated in a nationwide scale and the causes are classified into six categories. Of six categories the most important factors are 1) obstruction of continuous...

Wave-Induced Scour Prediction at Vertical Walls
Scour at the foot of a vertical wall is examined for the special case of normally-incident, nonbreaking irregular waves that are perfectly reflected by the wall. The bottom is initially...

Monitoring of a Nearshore Disposal Mound at Silver Strand State Park
The migration of an underwater disposal berm constructed in December 1988 approximately six miles south of the entrance to San Diego Bay is investigated. The berm was composed of medium...

Mound Migration in Deeper Water and Methods of Categorizing Active and Stable Depths
Sustained shoreward migration of several dredged material disposal mounds, including one in 6-m depths off the Alabama coast, should encourage greater use of nearshore placement to conserve...

Design Guidance for Nearshore Berm Construction
Construction of nearshore berms has been gaining acceptance as a cost effective beneficial use of dredged material. This paper presents a systematic methodology for design and evaluation...

A Systematic Analysis of Disposal Site Stability
This paper describes a systematic methodology for predicting the stability of dredged material disposal sites over long periods of time, ranging from months to years. The approach is based...

Analysis of Transport Processes on Ocean Disposal Mound
Disposal site 'F', an ocean disposal site for dredged sediments from Coos Bay, Oregon was designed to be a dispersive site. The site has not demonstrated high...

Dredge Spoil and Inner Shelf Investigations off Tauranga Harbour, Bay of Plenty, New Zealand
Dispersion of dredge spoil from an inner shelf dump-mound in 11-17 m water depth, 3 km offshore from Tauranga Harbour, Bay of Plenty, New Zealand, was investigated as part of environmental...

Influence of Water-Level Variation on the Performance of Great Lakes Beach Nourishments
In an effort to evaluate the influence of Great Lakes water level change on beach nourishment profile adjustment, an extensive ten year monitoring study was conducted in southern Lake...

Littoral Environmental Considerations of a Barrier Island in Beach Fill Design: Key Biscayne, Florida
An analysis and understanding of morphodynamic and littoral processes along a coastal shoreline is important in design of a beach fill project. Morphodynamic analysis should include a...

Performance of a Beach Nourishment Project Based on Detailed Multi-Year Monitoring: Redington Beach, FL
A recent monitoring project of a beach nourishment project includes closely spaced profiles and sediment analysis which provides data on nourishment performance which can be used in management...

The Use of Aragonite as an Alternate Source of Beach Fill in Southeast Florida
The first full-scale use in the United States of imported aragonite sand for beach restoration was initiated at Fisher Island, Florida, in December, 1990. The project involved placement...

Controls on Sand Resources: Cape Canaveral Area, Florida
Analysis of Holocene stratigraphy and sediments of the continental shelf off Cape Canaveral Florida shows that three basic factors control the quality of sand resources. Antecedent topography...

Cross-Shore Sediment Transport Determined by EOF Method
Laboratory and field data of beach profile changes are used to study the cross-shore transport rate. The Empirical Orthogonal Eigenfunction analysis is applied to separate the temporal...

Higher Frequency Acoustic Measurements of Coarse Bedload Transport
Although sensors have been developed which provide high temporal resolution for the measurement of wave profiles, flow fields and suspended sediment concentrations within the coastal system,...

Standing Wave Measurements of Bedload Thickness: Feasibility in an Air System with Model Sediment
A novel technique would yield information about bedload thickness from measurements of a standing wave pattern produced by a sound source insonifying the bottom at normal incidence. The...

Integrated Photogrammetric and Geophysical Monitoring of Shoreline Instability in Littoral Cells in the Pacific Northwest, USA
Several factors have recently focused on the attention of government agencies, academic researchers, and the general public on coastal erosion and beach resource management in the Pacific...

Coastal Sediment Budget Analysis Techniques
Sediment budget analysis techniques developed by the U.S. Army Corps of Engineers Wilmington District are described. The basic procedure combines information on shoreline and tidal inlet...
