New Methodology for Optimization of Freshwater Inflows to Estuaries
The objective of this paper is to present a new methodology for determining the optimal fresh water inflows into bays and estuaries to maximize fish harvest while satisfying the freshwater...
Using a Numerical Model to Evaluate Striped Bass Management Scenarios in the Sacremento-San Joaquin Delta, California
Since the mid-1970's, the striped bass, Morone saxatilus, population in the Sacramento-San Joaquin Delta, California has been declining. The primary suspected cause of the decline is associated...
Hydrodynamic Modeling for Channel Barrier Design
A two-dimensional vertically-averaged finite element hydrodynamic model was used at two scales to predict flow conditions for design of a proposed fish barrier: one for the general hydraulic...
Two-Dimensional Hydrodynamic Modeling with a Computer Graphics System
For more than a decade various divisions and district offices of the U.S. Army Corps of Engineers have been active in the development of graphic information system databases and computer...
Hydrodynamic and Toxic Contaminant Dispersion in the Lower St. Marys River
A numerical model that simulates the hydrodynamics and the transport of toxic contaminants in the Lower St.Marys River is being calibrated and verified using field data from the U.S. Army...
Wind Induced Circulation in Shallow Lakes
Clear Lake is a relatively shallow lake in Northern California. Natural flows are small but at times they do transport heavy metals into the lake. In order to predict water quality constituent...
Recent Developments in Three-Dimensional Numerical Estuarine Models
For a fixed cost, computing power increases 5 to 10 times every five years. The readily available computing resources have inspired new modal formulations and innovative model applications....
Integrated Planning Analysis for an Aggregate Mine
Planning and design work of an aggregate mining facility within the Sutter Bypass, a key component of California's flood control system, is being performed by multidisciplinary team of...
A Diffusion Hydrodynamic Model of a Shallow Estuary: Verification
Many of the hydrodynamic models used for estuary tidal flows and storm surges are based on two two-dimensional hydrodynamic equations which are obtained form the full three-dimensional...
Modeling Vertical Stratification in the Pamlico River Estuary Using Modern Hydrodynamics
A modern hydrodynamic model is applied to the Pamlico River estuary. Good agreement was obtained between measured and predicted water elevations and salinity distributions during the one...
An Engineering Assessment of Hydrodynamics and Beach Response at Little River Inlet, NC-SC
The Waterways Experiment Station's (WES) Coastal Engineering Research Center (CERC) conducted an analysis for the U.S. Army Engineer District, Charleston (SAC) of the monitoring data collected...
A Hydraulic Study of Venous Valve Closure
The functions of the veins is to convey blood from the periphery to the heart. The distribution and transportation of blood between different parts of the body is regulated by a host of...
NetCDF: A Public-Domain-Software Solution to Data-Access Problems for Numerical Modelers
Unidata's network Common Data Form, netCDF, provides users with an efficient set of software for scientific-data-storage, retrieval, and manipulation. The netCDF file format is machine-independent,...
Experiments with a Terrain-Following Hydrodynamic Model for Cobscook Bay in the Gulf of Maine
A terrain-following (sigma-coordinate) hydrodynamic model with 10 vertical levels and horizontal resolution of 225 m on a 70?60 grid has been applied to Cobscook Bay, located in the eastern...
