Validation of a Continental-Scale Storm Surge Model for the Coast of Delaware
Coastal structures are designed to provide protection against various forces of nature acting in the coastal zone. Structures such as seawalls are expected to provide onshore protection...
Numerical Modeling of Advective and Diffusive Transport in the Rappahannock Estuary, Virginia
A laterally integrated, two-dimensional real-time model, consisting of linked hydrodynamic and water quality models, was developed to study hypoxia in the tidal Rappahannock River, a western...
EPA's Environmental Monitoring and Assessment Program: Availability of Broad-Scale Environmental Data and Opportunities for Use in Environmental Modeling Applications
The Environmental Monitoring and Assessment and Program (EMAP) has collected a suite of environmental data over a four year period from estuarine systems in the mid-Atlantic and Gulf of...
Analyzing Larval Fish Distributions Using Hydrodynamic and Transport Modelling
Port Moller is a major spawning ground for Pacific herring. Coincident with extensive larval sampling in the estuary, data required for simulating three-dimensional hydrodynamics and transport...
Picturing Pollution
Kevin G. Coulton is a professional engineer and photographer who sees in the iridescent sheen of an oil slick on a rainy street a novel way to increase public awareness of water pollution...
Restoring the Everglades
Are constructed wetlands an effective management strategy for restoring and protecting the Everglades from phosphorus over-enrichment caused by agricultural stormwater runoff? The $13.85...
Boston's Backup Water Supply
For fifty years, Boston's sole real source of water has been the Hultman Aqueduct, but now final design is almost complete on the MetroWest Supply Tunnel, a new, larger conduit...
Federal Cleanups: Good News from Bad
Since the end of the Cold War the news about the Department of Energy has been grim: Thousands of acres poisoned with radioactive and toxic wastes, massive cleanup cost overruns due to...
NDBC Wave Data?Current and Planned
The National Data Buoy Center (NDBC) of the National Weather Service (NWS), operates a large number of buoy and fixed-platform environmental data reporting stations in geographical areas...
Implementing a National Wave Monitoring Network?Some Lessons and Plans
Most environmental problems involve a chemical and/or biological component and a physical processes component. A holistic approach must consider both components and the way they interact....
The TMA Wave-Energy Constraint and Cohesive Shore-Profile Shapes
A relation by Andreanov between wave-energy loss and nearshore slope, when combined with the TMA wave-energy constraint, is shown to closely approximate the classical Bruun/Dean shape....
Design and Testing of the NDBC Wave Processing Module
The U.S National Data Buoy Center (NDBC) has developed a new wave data acquisition and processing system, called the Wave Processing Module (WPM), using state-of-the-art technologies and...
Coastal Engineering Data Retrieval System (CEDRS)
The Coastal Engineering Data Retrieval System (CEDRS) is a menu driven microcomputer resident database which provides both hindcast and measured wind and wave data for use in the field...
Wave Attenuation at the Mobile Stable Berm
This paper describes work examining the ability of submerged berms to `filter' certain erosive wave energy while allowing accretionary type waves to pass unhindered. Analysis of wave data...
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...
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...
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...
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...
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...
