A Flexible Structural Analysis Method for Computer-Aided Preliminary Design
This paper presents a new method for supporting structural analysis during preliminary design stage that is based on Gere's idea of 'moment distribution'. The extension is that in this...

Model Tests on Caissons
Laboratory tests were conducted on model caissons to better understand the settlement/deflection behavior of open ended caissons on sandy soil, with embedment depth, caisson diameter,...

When and How Can You Specify a Probability Distribution When You Don't Know Much?
This paper presents an excerpt from the proceedings of the above-named workshop, and gives an overview of both the workshop and the proceedings. Five papers with diverse and complementary...

Subjective De-Biasing of Data Sets: A Bayesian Approach
In this paper, we examine the relevance of data sets (for instance, of past incidents) for risk management decisions when there are reasons to believe that all types of incidents have...

Developments in Risk Analysis Commercial Software
There has been a marked increase in the number and type of commercial software packages available to support risk and uncertainty analysis. Monte Carlo simulations, the first such tool,...

Waste Minimization and Recycling by Microfiltration during Nitrocellulose Manufacturing
A plant survey was conducted to determine the amount of nitrocellulose (NC) discharged with process water from each of five sequential NC purification processes. Wastewater samples were...

Laboratory and Field Evaluation of Acoustic Velocity Meters
A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing...

Response of Velocity and Turbulence to Abrupt Changes from Smooth to Rough Beds in Open-channel Flows
Response of velocity distribution and turbulence characteristics to abrupt changes of bed roughness have been investigated experimentally with two-component laser Doppler anemometer (LDA)....

Optical Methods for Sediment-Laden Flows
A method of distinguishing between the signals from the liquid-seed particles and sediment particles, while using LDV in sediment-laden flows, is described. The validity of the method...

Anomalous Measurements in a Compound Duct
An anomalous velocity distribution on the 'flood plain' of a compound duct is reported and discussed. The tentative conclusion is that the phenomenon is to be explained by the co-existence...

Observations on the Growth of an Internal Boundary Layer with a Lidar Technique
The distribution of atmospheric water vapor across a step change in surface humidity (dry-wet) was observed by a Lidar measurement technique under neutral atmospheric stability condition....

The Great Lakes Forecasting System: An Overview
The Great Lakes Forecasting System is a full three-dimensional model-based system designed to make regularly scheduled predictions of the physical status of each of the Great Lakes. Due...

GLFSVIEW - GLFS Product Viewing Application
GLFSVIEW is a menu-driven Visual Basic application running under MicroSoft Windows. This application allows quick downloading, browsing, printing and display of two-dimensional data maps...

Nonlinear Hydrodynamic Pressures on Arch Dam Faces
A finite difference method was used to calculate the nonlinear hydrodynamic pressures on the rigid arch dam faces. The arbitrary reservoir shapes were transformed to a regular cubic by...

Size Characteristics of Debris Flow Deposition
The size distribution of debris flow deposition is extremely wide which may contain nearly all particles from clay and colloid to boulder. Particle size and composition have very important...

Effects of Particle Shape on Bedload Transport
The effects of particle shape on bedload transport in gravel-bed streams are examined using a similarity approach and fractional transport analysis for data from Piceance Creek, Colorado,...

A Mechanism of Pool Formation and Maintenance in Forest Streams
Laboratory and field investigations illustrate a hydraulic mechanism responsible for the formation and maintenance of pools associated with large, in-channel obstructions in forest streams....

Determination of Geometry and Stress Distribution of an Optimal Stable Channel
A numerical model which determines the geometry of a threshold channel was recently developed (Diplas and Vigilar, 1992). This is important in the design of irrigation canals, channelization...

Luo, Ming
The algebraic stress model of turbulence is employed to calculate the 2-D flow field of the Gongzhui reservoir region. The discharge distribution among the discharging structures is achieved...

Scour Hole Depth Downstream of the SAF stilling Basin
A Model to predict the maximum local scour depth downstream of the SAF stilling basin is presented. The model is based on stability analysis of a particle attacked by the hydrodynamic...
