Portable data acquisition systems composed of IBM compatible PC/XT/AT computers and analog to digital conversion cards can be configured with relative ease. These systems have the flexibility...
3-D Hydrodynamic Model Verification Using ADCPS
A physically comprehensive, hydrodynamic model of the East River has been used for a continuous three year simulation. As part of the calibration process, detailed vertical profiles of...
Investigations on 3-D Flow Structures in Combined Systems of Groynes and Harbour Basins
The structure of the flow field in harbour basins shows significant three-dimensional (3-D) effects, e.g. variation of the direction of the horizontal velocity components with depth, existence...
Prescribed Solution Forcing Method for Model Verification
This paper describes a method for verifying the consistency and order of accuracy of a numerical implementation of a pde-model. We present an example of its application to a 3D hydrodynamic...
Application of a Geographic Information System to Estuarine Hydrodynamic Modeling
A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display,...
Two-Dimensional Hydrodynamic Modeling of a Reach of the Mississippi River in Pool 19
A depth-integrated finite-element model (RMA-2V) was applied on a section of the Upper Mississippi River to study the hydraulic characteristics of the floodplain-river system. The area...
Turbulence and Reynolds Stress Distribution in a Natural River
Turbulence characteristics of ambient flow velocities and their comparison with those generated by the movement of barge traffic within the channel border area in a navigation waterway...
On The Application of Artificial Viscosity in Computational Hydraulics
Artificial viscosity is a particular kind of truncation error that is either implicity present or explicitly added to the finite difference schemes. It is shown that the method of lines...
Uncertainty Quantification in Water Distribution Parameter Estimation
Calibration for water distribution system model parameters is usually undertaken with a minimal amount of field measurements so additional pseudomeasurements are assumed. Both the actual...
Modeling of Dispersion in Natural Streams with Pools and Riffles
The non-Fickian nature of the dispersion process in natural channels with pools and riffles has been investigated through both laboratory experiments and the numerical solution of a proposed...
Verification of WASURO Using the Puerto Nuevo Physical Model Study Results
The Jacksonville District, US Army Corps of Engineers, used the hydraulic design computer modeling program, WASURO, for preliminary design of the Rio Puerto Nuevo Flood Control System....
Daily Drought Monitoring by the Use of Existing Hydrologic Records
To manage water efficiently in case of drought, an effective drought monitoring method has been of interest. Drought durations and their conditional probabilities are estimated by applying...
An Engineering Analysis of Sedimentation in Tidal Inlets
The engineering comparative analysis of deposition and scour of noncohesive sediments in the neighborhood of bridges over tidal inlets is a unique problem which does not lend itself conveniently...
Numerical Modeling of Proposed Channel Designs (J. F. Baldwin III), California
Ship simulator studies of proposed improvements to navigable waterways are a very important part of any assessment. The John F. Baldwin Channel (JFB) Project (Phase III) is a ship channel...
Drought-related West Tennessee Channel Bank Failures
Massive bank failures occurred in 1988 along a 14-kilometer reach of the lower Obion River channel in Dyer County, West Tennessee where the river flows through an abandoned Mississippi...
Fluvial Recharge of Sand Mining Pit
Accuracy in modeling fluvial processes becomes increasingly important as development occurs along waterways. The FLUVIAL-12 (1, 2) model is used to simulate the recharge of sand mining...
Construction Product Performance, The Unexpected
Efforts made in the construction, industry to increase the quality of the constructed facility through the development of new materials and systems and through the reduction of labor intensive...
Computer Assisted Design and Construction
This paper presents a comprehensive package for conducting structural analysis, design, and project management on microcomputers. Several examples are presented to illustrate the usefulness...
