HEC River Analysis System (HEC-RAS)
The Hydrologic Engineering Center (HEC) is developing next generation software for one-dimensional river hydraulics. The HEC-RAS River Analysis System (HEC, 1994) is intended to be the...
Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...
What is Computational Hydraulics?
Computational hydraulics deals with methods and techniques for the numerical simulation of water flows in natural or man-made systems with the aid of computers. Flow and transport modeling...
A Lagrangian Model for Surface Buoyant Jets
A model is developed to predict the trajectory of a surface buoyant discharge into a large receiving water body. A Lagrangian approach is used to trace the path of a `control volume' of...
Improved Hydraulic Features of the HEC River Analysis (HEC-RAS)
The Hydrologic Engineering Center (HEC) is in the process of developing a Next Generation (NexGen) of hydrologic engineering software. The goal in the area of river hydraulics is to develop...
MAC3D: Multiblock Numerical Model for Hydraulic Applications
The MAC3D computer code is a three-dimensional numerical model for incompressible flow. To enhance geometric flexibility, it uses multiblock grids, which are composite structured grids...
Numerical Simulation of One Dimensional Transcritical Flow
The term transcritical flow describes the existence of both subcritical and supercritical flow simultaneously within the computational domain. Transcritical flow situations are encountered...
Depth-Averaged Flow Model in Curvilinear Coordinates
Implementation of a depth-averaged model in orthogonal curvilinear coordinates permits to resolve questions about grid refinement, the representation of complicated boundaries, and the...
Design of Manning's-Rougness-Coefficient Study in New York State
Field-collected hydraulic data can be used to compute roughness coefficients for channels with different hydraulic characteristics. Suggested criteria for the design of a roughness-coefficient...
An Approach to the Calculation Method of Mean Sediment Size
Mean sediment size is an important parameter expressing the characteristics of sediment. Several calculation methods of mean sediment size which are popular at present almost have some...
Ambrose, R. B.
Numerous three-dimensional hydrodynamic models have been developed in the last two decades. The developers of each model have used their own methods to verify the codes before applying...
PSF-PM Verification of 3D Free Surface Flow Models
This paper reports an application of the Prescribed Solution Forcing (PSF) and Physical Modeling (PM) to the development of a systematic procedure for the verification of three-dimensional...
Multi-Reservoir System Simulation Design Using C++ and Object Oriented Programming
Scientists and Engineers intuitively perceive the world as objects with interactions and internal processes. Physicists may view there work as different particles exerting forces on each...
Historical Rainfall-Runoff Analysis Using the Antecedent Precipitation Index
A long term simulation of rainfall-runoff can be used when analyzing the potential for economic benefits or flood damages to result from changes in the watershed, for developing discharge-frequency...
Hocking River Sedimentation Study
The channel improvement project located on the Hocking River in Athens, Ohio is estimated to have prevented over 68 million dollars in flood damages since its completion in 1971. However,...
An Interagency Overview of Selected Stream Sedimentation Models
The author's experience in developing stream sedimentation models is presented. The interagency study consisted of three phases. Phase one involved making an inventory of the computer...
Development of an Experimental Watershed for Testing Nonpoint Source Pollution from Urban Runoff
The U.S. Environmental Protection Agency (EPA) National Pollution Discharge Elimination System (NPDES) stormwater regulation program prohibits non-storm water discharges into entering...
Salinity and Dissolved-Oxygen Dynamics in a Wind-Driven Estuary
Water levels, near-surface and near-bottom salinities, and near-surface and near-bottom dissolved-oxygen concentrations were measured continuously in the Pamlico River estuary, North Carolina,...
