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...
Green's Function Implementation for Pile Analysis
This paper describes the implementation of a new Green's function based on a layer stiffness approach in a boundary element analysis of harmonically loaded pile groups embedded...
Random Vibration of Mass-Loaded Rectangular Plates
The classical method of separation of variables in conjunction with the Green's function of the vibrating plate is used to obtain the solution of the free vibration problem...
Bounded State Control of Structures with Uncertain Parameters
The control of linear systems in the presence of set constrained external disturbances has been investigated maintaining the states in a prespecified region by estimating the maximum reachable...
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...
Effect of Particle Size on Sludge Dewaterability
Using a modified Buchner funnel apparatus to measure specific resistance and a sequential centrifugation/filtration procedure to fractionate a sludge, it was possible to more precisely...
Intelligent Central Database System for Synchronized Distributed Processing of Large Hydrologic Packages in Local Area Networks
The nodes of a local area network can be dedicated to the independent routines of a large hydrologic/hydraulic package. The server of the network can be dedicated to the control of the...
Sedimentation Problems of the California Aqueduct
The California Aqueduct crosses the alluvial fans of many intermittent streams on the west side of the San Joaquin Valley. At two sites where watershed sediment yields were underestimated,...
Erosion and Sedimentation Processes in Irrigation
Soil erosion occurs when fluid in motion detaches and transports soil particles. Sedimentation occurs when the fluid transport capacity decreases. Both the hydraulic forces of moving water...
Lagrangian-Eulerian Approach to Modeling Contaminants
A Lagrangian-Eulerian modeling approach predicts potential contaminant distributions resulting from the disposal of sewage sludge at the Deepwater Municipal Disposal Site off the northeast...
Irrigation in Mexico
Mexico has a great historic tradition in the construction of works for irrigation; irrigated agriculture has been practiced since the pre-hispanic epoch. The development of hydro-agriculture...
Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...
Solving Nonlinear Equations on a Hypercube
Certain classes of nonlinear systems of equations, such as polynomial systems have properties that make them particularly amenable to solution on distributed computing systems. Some algorithms,...
Optimization for Overall Stability
This paper synthesizes design of trusses for linear stability constraint as an optimization problem where linear stability is defined as a generalized eigenvalue problem and presents a...
The Use of ISMAUT in Determining the Most-Preferred Package of Alternatives
Multiattribute decision analysis serves as a useful model of alternative selection under risk. A specialized form of multiattribute decision analysis assumes that there is only one stage...
Influence of Surface Conditions on Surface Temperature
Geotechnical engineers working in areas of discontinuous permafrost are frequently faced with the necessity of designing facilities with a minimum of thermal disturbance. Construction...
