Summary of Floods and Droughts in the United States
This paper describes a current national analysis of streamflow data being conducted by the U.S. Geological Survey to identify and map, in a consistent State-by-State format, the frequency...
Entropy as a Probability Concept in Energy-Gradient Distribution
The concept of entropy based on probability theory instead of thermodynamic principle has been applied to study the distribution of energy gradient along alluvial rivers. The formulas...
Discharge Measurement by Thermal Dilution
A flume study was conducted to develop and improve the thermal dilution method of discharge measurement in trapezodial channels. The study was performed in an indoor channel with dischages...
Flow Through Fish Bypass Intakes
Hydraulic and computational fluid dynamic models were used to investigate the cause of the unequal intake flow distribution observed entering the three vertical intakes of the patented...
Fatigue Reliability of Space Structures
This paper develops a methodology for calculating the probability distribution for rainflow cycles in a nonstationary Gaussian process. The up and downcrossing rates are estimated for...
Planar Space Structures
This paper describes a construction system which has a number of practical advantages for the development of space structures. It uses relatively thin materials folded into interpenetrated...
Non-Ionizing Radiation Exposure in Space Activities
Non-ionizing radiation exposure has received considerable attention over the past few years due to the potential health hazards involved. Different limits have been set with no international...
Probabilistic Methods in Civil Engineering
This book contains extended abstracts of papers presented at the ASCE Specialty Conerence on probabilistic methods held in Blacksburg, Virginia on May 25-27, 1988. The field of probabilistic...
Probabilistic Site Strategy for Transmission Lines
A probability-based geotechnical site characterization strategy is presented for transmission line structures. Because site-specific data are sparse for these structures, a Bayesian model...
Analysis of Berth Operability by Utilization of Agitation Models
Agitation models are utilized in order to predict the operability of berths for ship unloading purposes. Usually, in such models all ship displacements are measured and when one of them...
Forecasting Currents in Coastal Waters
A service for current and temperature forecasts has been developed for the coastal waters along the west coast casts has led to several improvements. Future modeling efforts are expected...
Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...
Simultaneous Releases from a Stratified Reservoir
The concept of simultaneously, selectively withdrawing water from multiple levels in a thermally, and therefore density, stratified reservoir is presented and its usefulness discussed....
Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Design Considerations for Hydraulic Jump Structures
The primary purpose of this paper is to define the areal distribution of large-scale pressure pulses acting on the containment structure of a hydraulic jump. The results presented are...
Minimum Energy Loss and Velocity Profiles in Pipes
Minimum energy loss in a flow is discussed. The concept is applied to derive velocity distributions for laminar flow through a circular pipe and steady uniform turbulent flow through a...
Joint Consideration of Pipe Breakage and Pipe Flow Probabilities
Two issues of distribution network reliability, namely, probability of pipe failure and probability of the design flow being exceeded have been discussed. Expressions containing measures...
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...
Analytical Simulation of Bulk Water Supply Network Reliability
The authors present an analytical method for estimating failure probabilities for a bulk water supply network with spatially dispersed supply, demand, and storage. The method examines...
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....
