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...

Kinematics of Wave Overtopping on Marine Structure
Kinematics of transient wave overtopping on coastal breakwaters has been studied both experimentally and numerically. For the laboratory experiments, solitary waves with moderate wave...

Evolution of Breaking Directional Spectral Waves in the Nearshore Zone
Methods used in parabolic refraction-diffraction models for computing the evolution of monochromatic waves in the nearshore zone are used to construct a model for spectral wave conditions....

The Significance of Hydrodynamic Forces in Coastal Embankment Design
The dynamic forces of sea water and backfill soil acting on coastal embankment are analyzed by using a new finite-difference method. The Euler's equation and continuity equation are used...

ASA.WAVES: An Interactive PC-based Wave Forecasting Tool
An interactive PC-based system for wave refraction-diffraction in coastal regions has been developed, based on a Mild-slope equation finite element wave model. The system includes an embedded...

Joint Probability of Superelevated Water Levels and Wave Heights at Duck, North Carolina
Storm events are typically classified as a percent occurrence or return interval based on their peak storm elevation. The stage is the combination of storm surge, astronomical tide and...

Estimating Laboratory Wave Reflection Using Laser Doppler
Estimates of irregular wave reflection in two-dimensional laboratory wave tanks are typically accomplished using an array of spatially separated wave gauges. This paper presents a frequency...

Observations of Wind Wave Growth by ERS-1 SAR
Spatial variations of ocean waves can be observed from space-borne synthetic aperture radar (SAR) images of ocean surface. For a steady offshore wind, the growth of wind wave from an upwind...

Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...

Breaking Wave Measurement by a Void Fraction Technique
Breaking of steep surface gravity waves in seas under moderate to strong wind forcing always involves the entrainment of air into the water column below the air-sea interface. As such,...

Case Studies of Extreme Wave Analysis: A Comparative Analysis
Several methods of extremal wave analysis have been applied to two sets of deep water extreme wave data. One set consisted of three-hourly sea-state records collected during a nine year...

Design Waves and Wave Spectra for Engineering Applications
Thirteen years of hourly wave data measured at two of the National Data Buoy Center's (NDBC) buoy stations, one located in the northeastern Pacific and the other located in the northwestern...

Wave Transformation and Load Reduction Using a Small Tandem Reef Breakwater ? Physical Model Tests
The performance of several small reef breakwaters, and a tandem breakwater system (consisting of a reef breakwater positioned upwave from a surface-piercing main breakwater), are quantified...

The Evolution of Breakwater Design
The purpose of this paper is to present a view of the evolution of both the rubble mound and vertical faced breakwaters from the earliest design through the Iribarren and Hudson era. Determining...

The Determination of Typhoon Design Wave By Synthetic Probibility Method
In summer and autumn, typhoons always take place in the northwest pacific. in the northern hemisphere, the typhoon is a large, anticlockwise, atmospheric eddy. Due to the strong wind speed,...

Hydraulic Properties of Surface Runoff on Ash-Mixed Concrete Pavement
The disposal of incinerated sludge ash from wastewater treatment plants is becoming an increasingly difficult problem in highly populated cities. The feasibility of reusing sludge ash...

Optimal Operation of Soil Aquifer Treatment System
Mathematical models based on nonlinear programming are developed for operating soil aquifer treatment(SAT) systems. The objective of these optimization models is to determine the operation...

Retaining and Flood Walls
The engineering manual Retaining and Flood Walls from the U.S. Army Corps of Engineers provides guidance for the safe design and economical...

Random Vortex Models in Wind Engineering
Random vortex methods are Lagrangian particle-based numerical simulation schemes especially appropriate for Wind Engineering simulations. Vortex methods do not suffer from numerical diffusion...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...
