The Effect of Beach Vegetation on Aeolian Sand Transport
The effect of coastal vegetation on aeolian sand transport is examined through consideration of the governing aerodynamic processes. Local scale processes without the effect of ground...

Littoral Dune Transport and Morphology Under a Variable Wind Regime
Most of the large dunes are generally produced by a permanent or quasi-permanent winds. Usually winds present strong concentrations of its directional spectrum around its mean direction....

Measurements of Suspended Sediment Transport: Prototype Shorefaces
Field measurements of local time-varying suspended sediment flux were obtained using rapid response velocity and sediment concentration sensors at a number of elevations under shoaling...

Field Measurements of the Vertical Structure of Suspended Sediment
The use of acoustic backscatter measurements to determine suspended sediment concentration gives a new view of the instantaneous sediment distribution as a function of height above the...

G6 Coastal Morphodynamics
The contents and the backgrounds of the European coastal modelling programme 'G6 Coastal Morphodynamics', in the framework of the EC-sponsored Marine Science...

The British Beach and Nearshore Dynamics (B-Band) Programme
A large scale collaborative field based research programme (B-BAND), aimed at measuring the small scale processes associated with nearshore dynamics on macro-tidal beaches, is currently...

Monitoring the Response of the Inter-Tidal Beach Profile to Tidal and Wave Forcing
The need for sets of beach profile and wave data of one year duration, sampled at sub-weekly intervals, is well recognised in the literature. Some of the initial data from a macro-tidal...

Effect of the Earth Rotation on Tide Induced Sediment Transport
Semi-enclosed seas are generally composed of narrow straits and wide basins, forming a strait-basin system. In the strait-basin system where tidal current prevails, the strong tidal current...

Sediment Transport by Strong Wave-Plus-Current Flows
A prediction formula is derived for the suspended sediment transport rate in coastal regions when the current speed and/or wave orbital velocity is large. It is based on generalised forms...

Effects of Fluid Accelerations on Sediment Transport in Surf Zones
Two hydraulic model tests were run in a wave flume using irregular waves to obtain detailed data on the cross-shore variations of the pressure gradient on a 1:20 smooth, impermeable slope....

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...

Mean Currents and Sediment Transport at DELILAH
Bailard's sediment transport model (1981) is used as a framework to test the hypothesis that mean currents can dominate nearshore sediment transport. The data acquired during...

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...

Process Variation Across a Barred, Tidal Nearshore
Detailed measurements of nearshore motions and morphologic change across the inner bar-trough of a barred, tidal beach were taken at Canaveral N.S., Florida. Tidal range was <1...

Shoreface Connected Ridges Along the Dutch Coast
Quasi-synoptic current measurements were obtained across the Dutch shoreface connected ridges using an acoustic Doppler current profiler. The measurements are used to evaluate the role...

Sand Ridges and Internal Waves on Continental Shelves
Large-amplitude internal waves generated by tidal fluctuations at the outer edge of the continental shelf propagate shoreward and interact with sediment on the shelf. A crude mathematical...

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...

Modelling of Cross-Shore Flow and Morphology
A one-dimensional, time-dependent model is presented which describes the evolution of wave groups and associated long waves over an arbitrary profile, in a short-wave averaged sense. Model...

A Model for Profile Changes During Storm Surges
In order to predict the amount of dune erosion due to a storm surge, a model for cross-shore transport during storm surges has been developed. During a storm with intensive wave breaking,...
