SQP Methods for Inverse Airfoil Design
We consider inverse design problems of systems governed by suitable discretizations of a boundary value problem (BVP). We present and examine a Sequential Quadratic Programming (SQP) method...
Simulated Circulation and Transport in Adjacent Wind-Driven Estuaries in North Carolina
The Pamlico and Neuse River estuaries, in North Carolina, display similar physical characteristics because of their proximity and physiographic setting. Yet, because of channel configuration...
Nowcast System Development for the Straits of Florida
As part of the inaugural program for the Ocean Pollution Research Center at the University of Miami, a nowcast system is being developed for the Straits of Florida. The nowcast system...
Effects of Flocculation on Particle Transport
On the basis of previous experimental and theoretical work on flocculation rates and the settling speeds of flocs, an accurate and computationally efficient model of the aggregation and...
The Formation of a Turbidity Maximum in an Estuary
In the present study, a numerical model is used to investigate the transport of sediments in a stratified estuary. The model includes sediment resuspension and deposition as well as three-dimensional,...
Numerical Simulations of the CCS under the Joint Effects of Coastal Geometry and Surface Forcing
Using the S-Coordinate Rutgers University Model (SCRUM) of Song and Haidvogel(1993), a coupled coastal (86 m depth) and deep ocean (4600 m depth) California Coastal region has been investigated...
Demonstration of the Wes New York Bight Hydrodynamic Model in Long Island Sound
Recently, a three-dimensional numerical hydrodynamic model of the New York Bight developed by the Waterways Experiment Station was applied to the Long Island Sound subregion, using NOAA's...
Observations Related to the Use of the Sigma Coordinate Transformation for Estuarine and Coastal Modeling Studies
One of the common techniques used in application of time-dependent, three-dimensional models addressing estuarine and coastal environmental problems is the sigma coordinate transformation....
Solutions of Primitive Equations for Three-dimensional Tidal Circulation
Readily available computing resources and new numerical methods have made it possible to reproduce detailed three-dimensional tidal circulation with very fine spatial resolution, and covering...
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...
Experimental Study of Undertow and Turbulence Intensity Under Irregular Waves in the Surf Zone
Experiments are performed in a two-dimensional wave tank with a sloping beach. Irregular waves are generated and the water particle velocity is measured in the surf zone with a laser Doppler...
The Time Dependent Ray Method for Calculation of Wave Transformation on Water of Varying Depth and Current
This focuses on an aspect of the numerical calculation of wave refraction using the ray tracing or the semi-Lagrangian approach. the conventional ray method for steady state depth and...
Second Order Irregular?Wave Generation in Flumes - Computation of Transfer Functions by an Asymptotic Summation Method
Recently the theory for second order irregular-wave generation (including superharmonics as well as subharmonics) has been rederived for a variety of different types of wave board motion....
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...
Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....
A Satellite Based River Forecast System for the Nile River
The initial version of the Nile Forecasting System developed by NOAA was used operational in July, 1993. Forecast System accuracy exceeded expectations. The Nile Forecast Center is now...
