A multi-dimensional transport model based on the RMA series of finite element models has been developed utilizing a characteristic-Galerkin approach. This paper examines the application...

Boundary Forcing and a Dual-Mode Calculation Scheme for Coastal Tidal Models Using Step-Wise Bathymetry
Tidal energetics are persistent and important factors in almost all coastal regions. As such, it is important to employ techniques that can consistently reproduce observed tidal variations....

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...

Comparison of Eulerian-Lagrangian, Random Walk and Hybrid Methods of Modeling Pollutant Transport
An Eulerian-Lagrangian, a random walk, and a hybrid model were compared in terms of their accuracy and efficiency in simulating two-dimensional pollutant transport. Computer experiments...

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...

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...

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...

Estimation of Directional Spectra by ML/ME-Methods
The paper discusses the statistical Maximum Likelihood (ML) and Entropy (ME) methods for estimation of directional wave spectra. A combined ML/ME method is derived, and a reduced version...

Implementation and Validation of a Global Third-Generation Wave Model at Fleet Numerical Oceanography Center
The third-generation Wave Model (WAM) is currently being implemented at the U.S. Navy's Fleet Numerical Oceanography Center (FLENUMOCEANCEN) to replace the operational Global Spectral...

Comparisons of Directional Wave Analysis Methods
Four methods analysing directional wave spectrum were testes and compared through numerical simulation. The four methods are (i) the truncated Fourier series (TFS), (ii) the Longuet-Higgins...

Evolutionary Fourier Analysis of Wave Data
A new method is presented for analyzing nonstationary water level height time series. The usual assumption of pseudo-stationary intervals is avoided and the wave spectra can be changing...

Extensive Comparison of Directional Wave Analysis Methods From Gauge Array Data
In order to settle an efficient operational wave gauge array for estimating directional wave spectrum, several directional analysis methods are implemented and compared. These methods...

Kinematics of Wave Overtopping on Marine Structure
