Confidence Intervals for Flood Control Design
The line drawn and labeled as the flood frequency curve is seldom identified as to what confidence is associated to the plot. For example while flood control designs are typically based...

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...

An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Recent Developments of the Finite Strip Method
The finite strip method is approaching a state of maturity as a structural analysis technique, as the well known finite element method has done. Two comprehensive (although somewhat dated)...

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...

Engineering Hydrology
The Surface Water Hydrology Committee, ASCE Hydraulics Division, sponsored this first Symposium on Engineering Hydrology. The Symposium was held jointly with the ASCE National Conference...

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...

Advance Prediction of Flow-Induced Variations
Frequency analysis of hydraulic vibrations has been applied using a transfer matrix and impedance method. The computer program is given for the self-excited and forced vibrations, together...

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...

Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...

Frequency Domain Analysis of a Tank-Soil System
The dynamic response of an elastic cylindrical tank supported on a rigid base under a harmonic vertical excitation is analyzed taking into consideration its interaction with the foundation...

Adaptation of Modal Testing Procedure to Shaker Tables
This article presents a technique for adapting current modal testing procedures to shaker table tests commonly used for qualification tests of nuclear and space related equipment. It involves...

Stochastic Response of Structures with Appendages Containing Fluids
Following a perturbation technique a procedure is developed to compute the modal properties of a system consisting of a fluid containing appendage attached to a multi-degree-of-freedom...

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,...
