Cross-Shore Sediment Transport Modelling and Comparison with Tests at Prototype Scale
A series of prototype scale laboratory experiments have been performed at the Large Wave Channel (GWK) in Hanover to investigate the process of sediment transport over a horizontal bed...

Estimation of Overwash Bore Velocities Using Video Techniques
Overwash data were collected at a site on the Isles Dernieres, LA barrier island chain during Hurricane Gilbert in September 1988. A video technique was applied that allowed the quantification...

Engineering Methods for Predicting Beach Profile Response
This papers contains a review of so-called 'engineering methods' for predicting beach profile change based on equilibrium profile concepts. In the first part...

Problems Associated with Deterministic Modelling of Extreme Beach Erosion Events
Recent developments in numerical modelling of cross-shore sediment transport and beach profile evolution have generally been based on a deterministic approach to the problem. That is to...

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...

Computer Simulation of Shore-Normal Variations in Sediment Size
A computer simulation model is presented which is designed to predict the selective shore-normal sorting of grain sizes in the nearshore environment. The model simulates wave shoaling,...

Effect of Varying Sediment Size on Equilibrium Beach Profiles
Beach profiles from four field sites and accompanying data describing the cross-shore distribution of median sediment size are analyzed and compared to predicted profiles based on an equilibrium...

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...

Observations of a Tidal Inlet on a Shingle Beach
An observation and measurement program was undertaken at Batiquitos Lagoon, San Diego County, California to better understand the paths and rates of shingle movement in the littoral zone....

Spit Formation in Lake and Bay
A technique of superimposing beach profiles, as a method for analyzing the characteristics and deformation process of a sand spit topography, is proposed, and the morphological changes...

Beach Profile Response to Hurricane Hugo
The impact of hurricane Hugo on the beaches of South Carolina is examined by comparing beach survey data collected during the spring and summer of 1989 with post-storm survey data collected...

Numerical Simulation of Beach Profile Response to Hurricane Hugo
Beach and dune erosion caused by Hurricane Hugo at Myrtle and Debidue Beaches, South Carolina was simulated using an explicit finite-difference cross-shore sand transport numerical mode....

Beach Profile Modelling: Flume Data Comparisons and Sensitivity Tests
Some results from a deterministic computational model of beach and nearshore profile development are presented in this paper. Comparisons are made with prototype-scale flume measurements...

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...

An Artificial Perched-Gravel Beach as a Shore Protection Structure
Gravel beaches provide the backshore of coastal environments with a protective buffer from wave erosion. A case study is presented of the conceptual design and utility of an artificial...

Beach Stabilization Using Drains?An Experimental Model Study
The use of the drain concept may be an attractive new tool for beach stabilization because it provides an alternative to hard structures and may enhance beach nourishment practices. Two-dimensional...

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...

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...

Development of Optimum Beach Fill Design Cross-Section
Accurate beach profile surveys, wave information, and sediment data taken at Ocean City, Maryland provided an opportunity to evaluate four beach fill design alternatives using the beach...
