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,...
Getting the Project Started
In 1987, the newly formed Washington Metropolitan Airports Authority began a long term Capital Development Program which will change how both Washington National and Dulles International...
The Future of the Past: Historic Preservation at the Metropolitan Washington Airports
The historic significance and unique architectural character of Washington National and Washington Dulles International Airports have presented the Metropolitan Washington Airports Authority...
Airport Terminal Design Challenges
In February 1989, the Metropolitan Washington Airports Authority began the process of designing and constructing a new terminal at Washington National Airport to address the needs of its...
Dulles International Airport Construction Challenges
The expansion of the Main Terminal at Dulles International Airport was anticipated and planned for during the original construction of the building in 1962. The most difficult portions...
Dynamic Loading of Airfield Pavements Caused by Aircraft Operations on Rough Runways
This paper presents results for dynamic pavement loading of various aircraft under takeoff and taxing scenarios. The data were obtained from computer simulation and applied to the Corps...
Implementation of Elastic Layered Theory for Design of Unbonded Overlays
The U.S. Army and Air Force have implemented the elastic layered theory for design of unbonded overlays for rigid airfield pavements. The procedure allows for design of unbonded overlays...
The Use of Crumb Rubber Modifier in Hot-Mix Asphalt
This paper summarizes the literature on the use of CRM as an additive in HMA. Wet and dry processes are discussed and the objective of each explained. Material, design and construction...
Modified Asphalt Binders - How Do They Compare?
This report summarizes some of the research that the US Army Engineer Waterways Experiment Station (WES) has conducted on asphalt modification of airport/airfield pavements. these laboratory...
Utilization of Phosphogypsum-Based Slag Aggregate in Portland Cement and Asphaltic Concrete Mixtures
This study centers around the potential utilization of phosphogypsum-based slag aggregate as a substitute for coarse aggregate in both portland cement and asphaltic concrete surfaces for...
