The Effect of Beach Slope on Oscillatory Flow Bedload Transport
The data for five laboratory sloping bed bedload sediment transport experiments are presented. Each consists of a series of half cycle transport rate measurements using the same waveform...
Grain-Shape Analysis of Littoral and Shelf Sands, Southern California
Estimation of the exchange rates and determination of transport mechanisms and pathways associated with the onshore-offshore vector is one of the greatest sources of error in sediment...
Beach Profiles vs. Cross-Shore Distributions of Sediment Grain Sizes
In the present paper, field results are reported from various tideless beaches in Greece with mixed sedimentary environments. The two classical beach profiles are examined in terms of...
Equilibrium Profile of a Beach with Varying Grain Size
The classical concave equilibrium profile shape proposed by Bruun (1954) and Dean (1977) is modified to incorporate a varying grain size across-shore. On most beaches the median grain...
The Sedimentary Organisation and Behaviour of Drift-Aligned Gravel Barriers
Drift-aligned barriers formed of coarse clastic materials and described in terms of their organisational evolution at two levels, a) sorting and selection of clasts; b) development of...
Problems with Predicting the Transport of Pumiceous Sediments in the Coastal Environment
Pumice is often a major component of coastal sediments associated with subduction zone volcanic settings. Several recent studies in New Zealand have highlighted the difficulties of predicting...
Historical Morphologic Evolution and Sedimentation at Barataria Pass, Louisiana
Barataria Pass, Louisiana, one of the most commercially important tidal inlets in the Gulf of Mexico, has undergone several stages of development since 1840. The shore-parallel growth...
Processes of Sediment Transport and Ebb Tidal Delta Development at a Jettied Inlet
This paper deals with the development of the ebb tidal delta following the extension of jetties at a tidal river entrance. The growth rate and morphological change are discussed using...
Sorting Characteristics of Tidal Inlets
An hypothesis is presented as follows: Littoral processes at a tidal inlet remove a disproportionately higher quantity of fine grain sediment than coarse grain sediment from the littoral...
Numerical Modelling of Lower Lias Rock Failures in the Coastal Cliffs of South Wales
A model has been developed to evaluate slope failure in the interbedded limestone and mudstone Lower Lias series which outcrop for some 30 km in coastal South Wales. Computer simulation...
Model Testing of Shore Protection Schemes at Surfside-Sunset Beach, CA
A 1:75-scale physical hydraulic model was used to investigate the design of proposed structural modifications at Surfside-Sunset Beach, California, with regard to beach erosion at the...
Physical Modelling of Pocket Beaches
The design of artificial beach systems is dependent upon the modelling criteria and on the selection of the sand material to be used for nourishment. In order to obtain a stable beach...
Initial Shoreline Response at the Presque Isle Erosion Control Project
Construction of the Presque Isle Shoreline Erosion Control Project in Lake Erie at Erie, PA began October 1989 and consists of fifty-eight offshore segmented breakwaters with beachfill....
Rehabilitation of the South Jetty-Ocean City, Maryland
The south jetty at Ocean City, Maryland was rebuilt in 1985 to reduce the frequent shoaling in Ocean City Inlet. The project consists of a new jetty offset 30 feet south of the existing...
Redington Shores Breakwater: Beach Response
This paper presents the beach response at Redington Shores, Florida to a detached offshore breakwater constructed in 1986. This paper summarizes the initial shoreline response described...
Comparison of Shoreline Change Obtained with Physical and Numerical Models
This paper describes a study performed to compare numerical simulations of shoreline response to coastal structures to the response measured in a large wave basin. Two cases are modeled...
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...
The Interaction of Seawalls and Beaches: Four Years of Field Monitoring, Monterey Bay, California
Coastal protection structures have historically been the most common approach to dealing with the problem of shoreline erosion in the United States. Three potential impacts of these structures...
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...
Artificial Headland and Submerged Groyne for a Beach Improvement Project
The design approach that was used to determine the length and elevation of a submerged groyne as well as a system for providing adjustment to the elevation of the submerged groyne is presented....
