Optimal Design of Large Scale Water Distribution Systems
This paper presents a methodology for the design of least cost water distribution systems. The advantage of the formulation compared to the other techniques in the literature is that it...
Cellular-Automata for Hydrodynamic Modeling
A two-dimensional fluid continuum system can be modeled using a discrete field of particles that interact according to simple deterministic rules. The methodology is called Cellular Automata....
Discharge and Depth Behind a Partially Breached Dam
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated....
Segregation of Sediment During Deposition
A laboratory experiment was conducted to investigate the segregation of sediment during deposition. Sediment eroded from an upslope source area of Blount silt loam was introduced to a...
Depleted Uranium Migration in Stream Bedload Environment
The objective of this paper is to present results of a comprehensive hydrologic transport study, designed to assess potential surface water contamination, resulting from the release of...
Versatile Methodology for Flow Depth and Velocity Modeling in Stream Aquatic Habitat Assessment
The habitat assessment methodology developed by the IFG Instream Flow Group is a useful tool for evaluating instream flow needs. The methodology for basin flow modeling developed in this...
Physical Model Verification of a Coastal Discharge
A 1:75 scale physical model of a thermal discharge into a rocky, semi-enclosed bay was verified against extensive field data. The model accurately reproduced the prototype temperature...
Steel Plate Girder Alternate I-10/I-17 Interchange
The scope of the Phoenix I-10 Viaduct allowed extensive study for the optimization of this moderate span steel plate girder bridge. The value engineering studies lead to the use of the...
An Analytically Derived Distribution Function for Flood Volume
A general stochastic model is proposed to determine analytically the distribution function for flood volume. A flood event in this study is defined as an unbroken sequence of consecutive...
A Versatile Methodology for Flood Frequency Analysis
Many observed annual flood series exhibit reverse curvatures when plotted on lognormal probability paper. The occurrence of these curvatures may be attributed to storm and basin factors....
Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
The GEV Distribution in Drought Frequency Analysis
Three decades have passed since A. F. Jenkinson found the general solution to the Stability Postulate, which is the condition that all the extremes must meet, and after him that solution...
Deriving Streamflow Distribution Probabilities
Streamflow distribution probabilities are often involved in the stochastic analysis of water resources systems. Limited by data availability, certain probability terms can hardly be abstracted...
Impact of Temperature on Columbia River Winter Floods
During the course of an extensive study of the Columbia River drainage to evaluate a major levee system near Portland Oregon, it was noted that flood runoff produced by winter storms with...
Teacher Friendly Transportation Programs
This contribution describes a set of computer programs that has mainly been developed to demonstrate operating and possibilities of mainframe programs during lectures. The program set...
FEM-Flow Analysis in Hydraulic Turbomachinery Runners
Finite element calculations of the flow through distributor and runner of hydraulic turbomachines are presented. The method is quasi-3D and inviscid, but the deviations from a potential...
Simulation of the Pit 3, 4 and 5 Hydroelectric Project Using the USFWS Instream Temperature Model
The Pit River in Shasta County, California, is the site of the Pit 3, 4, and 5 Project (Project). A two-year Bald Eagle and Fish Study was initiated in March 1983. As part of the overall...
Computer Modeling for a Power Intake
This paper describes the application of an existing computer model to respond to environmental requirements for a small scale hydroelectric power plant being developed by Allegheny Electric...
Combustion Sources of Residential Air Pollution: An Overview
Combustion by-products are a major source of indoor air pollution and have been measured in homes at levels above typical outdoor concentrations, and at levels which approach or exceed...
Modeling Dispersion in Non-Homogenous Formations
A stochastic model of contaminant mixing in non-homogeneous porous media has been developed. The model is three dimensional and relates the contaminant distribution to the probability...
