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,...

Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...

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...

Flocculation Kinetics Using Fe(III) Coagulant to Coagulate Kaolin Clay in Water: Effects of Temperature
Flocculation kinetics using ferric nitrate as a coagulant to coagulate kaolin clay in water was examined using several experimental factors. Both the particle size distribution data obtained...

Thermally Enhanced Bioremediation of a Gasoline-Contaminated Aquifer Using Toluene Oxidizing Bacteria
The combined application of steam injection and vacuum extraction has proved to be very effective for the in situ remediation of a gasoline contaminated aquifer. It is expected that the...

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...

Testing Turbine Aeration for Dissolved Oxygen Enhancement
During August of 1993 the Bureau of Reclamation tested turbine aeration for dissolved oxygen (DO) enhancement at Deer Creek Powerplant near Provo, Utah. This test required a variety of...

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...

Short-Term Forecasts for Lake Erie
Short-term forecasts for Lake Erie were generated by coupling a mesoscale atmospheric prediction system with a lake forecast system. The modeling systems used were The Pennsylvania State...

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...

Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...

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....
