New Directions in the Application of Probabilistic Concepts in the Seismic Analysis of Nuclear Power Plants
During the last 8 years, probabilistic concepts have been used in the seismic analysis of nuclear power plants. Probabilistic risk assessment (PRA) has been the primary vehicle for performing...

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...

Electronic Computation
The papers included in this book were presented during the thirteen sessions of the Ninth ASCE Conference on Electronic Computation. Topics addressed represent a wide spectrum of computer...

Probabilistic Study of SPT Liquefaction Analysis
The influence of earthquake magnitude upon the commonly used correlation between Standard Penetration Test (SPT) blow count and liquefaction potential is evaluated using a probabilistic...

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...

On the Ship's Waterways Passing Through Bridges
This paper reports on a study of bridge openings that serve as waterways, in view of the analysis of ship collision accidents. For the purpose of this study, cases of ship collision accidents...

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,...

The Reliability of Treatment Systems
The purpose of this paper is to present the results of case studies of zero and first order reactor systems and an activated sludge treatment system consisting of a primary settling tank...

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...

Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...

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...

Guidelines for Maintenance of Aging Water Pipes
Break failure patterns are investigated by applying a new methodology based on Proportional hazards and Poisson-type models. Application on two water distribution systems of North-Eastern...

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,...

Probabilistic Limit States Design of Moment-Resistant Frames Under Seismic Loading
This paper focuses on the development of a methodology for the optimal probabilistic limit states design of seismic-resistant steel frames. A mechanism for allowing the designer to include...
