On the Generation of Infragravity Waves by Shoaling Multidirectional Waves
The generation of long period waves in shallow water by shoaling multidirectional waves is investigate using both numerical simulations and laboratory experiments. The numerical model...

Anomalous Dispersion Paradox in Shallow Water Gravity Waves Shoaling Over Slopping Bottom
Pecularities of celerity spectra of shoaling gravity waves are considered. The results of flume and field experiments focused on the measurements of celerity spectra of shoaling gravity...

A Comparison of Wave Statistics in Uni- and Multidirectional Shoaling Seas
the transformation of six unidirectional and multidirectional seas propagating over a 1:25 planar beach are examined in a series of laboratory experiments. In all cases, the mean wave...

Shoaling of Wave Spectra in Front of Reflective Structures
Breakwater and jetty design depend in part on the incident significant wave height expected to reach the structure. This height is not always known and must be estimated from a deepwater...

An Offshore Island Wave Sheltering Model
The wave climate along Southern California Coastal area is greatly modified by the existing systems of natural islands shown. As deep water wave approach the nearshore area, they generally...

Spectral Boussinesq Modelling of Breaking Waves
Random waves passing over a shallow bar are considered, in particular the amplification of bound harmonics in shoaling water, their subsequent release in deepening water, and the role...

One- and Two-Dimensional Analysis of Flow in Hotophia Creek, MS
A numerical experiment on the influence of a sand bar encroachment on the stream flow pattern is reported. The results of a two-dimensional analysis were compared with results of an equivalent...

Sandbar Formation in Side-Diversion Channels
Prediction of sandbar formation in side-diversion channels is desirable in a wide range of river engineering problems. However, the mechanism by which they form is still not well understood...

Calculating Erosion Rates: Using Long-Term Data to Increase Data Confidence
Computer cartographic techniques were used to produce historical shoreline change maps for two study areas: (1) an eight kilometer section of Calvert County, Maryland; and (2) an eight...

The North Black Sea and the Sea of Azov Coasts Under a Possible Greenhouse-Induced Global Sea-Level Rise
The first attempt is presented to compile a map of coastal evolution of the Black Sea and the Sea of Azov under the possible accelerated greenhouse-induced sea-level rise by 1m (medium...

The Magdalen Islands, Gulf of Saint Lawrence
The Magdalen Islands constitute the largest barrier-island system in the Gulf of Saint Lawrence. They represent 435 km of coasts at the 1:50 000 scale, two-thirds of which are sandy and...

Halloween Wave Transformation Near Virginia Coast
The Halloween Northeaster of October 29-31, 1991 generated a unique severe sea. The storm waves propagated through two wave stations which are 87 km apart. The wave spectra of the storm...

Santa Barbara Harbor Assessment of Shoaling Frequency
The City of Santa Barbara is addressing the recurring problem of shoaling of its harbor entrance channel. The City relies on income generated from harbor businesses that in turn require...

Shoaling and Breaking of Random Wave Trains: Spectral Approaches
We describe recent efforts to develop a model to predict the evolution of the spectra of random ocean waves shoaling and breaking on a natural beach. A model based on the full Euler equations...

Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...

Coastal Engineering Practice
This proceedings contains 70 papers presented at the American Society of Civil Engineers Specialty Conference Coastal Engineering Practice '92 held at Long Beach, California,...

Optimal Scheduling of Advanced Maintenance Dredging
This brief article discusses conventional and new procedures for nourishment of beaches taking advantage of recent years' development of more effective equipment of smaller...

Wave Shoaling on Uniform Currents
The purposes of this paper are to investigate the characteristics of waves coexisting with uniform currents on a sloping bottom. The theoretical calculations of the third order approximation...

Debris Removal and Channel Shoaling
Hurricane Hugo was one of the worst storms of the century to strike the east coast of the United States. The storm tracked a northwesterly course approximately 11:30 P.M. on Sep. 21, 1989....
