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...
Risk and Reliability of Water Resources Infrastructure and Engineering Approaches to Risk and Reliability Analysis
The paper summarizes the second session of the conference which discussed the risk and reliability of water resources infrastructure as well as engineering approaches to risk and reliability...
Treatment of Oil in Water Emulsions by Ceramic-Supported Polymeric Membranes
A novel membrane was developed by growing polymer chains from the surface of a porous ceramic support, resulting in a composite membrane which combines the mechanical properties of the...
Evaluation of Fe oxide-coated GAC for removal and recovery of Cu(II) from water
A composite solid, prepared by precipitating an Fe oxide onto granular activated carbon (GAC), was evaluated as an adsorbent for the removal and recovery of Cu(II) from water. Relative...
Chelating Composite Membrane: Its Application in Selective Heavy-Metal Solid-Phase Separation
Selective removal of small amounts of heavy metals from the background of large amounts of innocuous sludge or slurry is a challenging separation problem. Conventional fixed-bed sorption...
Modeling of Chemical Inhibition of Nitrification
This work contains two quantitative structure-activity relationships (QSARs) modeling chemical inhibition of nitrification, one for heterocyclic compounds and one for acetylenic materials....
Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...
DBP and Hardness Control by Membrane Filtration
Ultra (UF) and nanofiltration (NF) were evaluated for removal of disinfection by-product (DBP) precursors and hardness from Rio Grande water in New Mexico and Texas. In order to compare...
Treatment of Drinking Water Containing Bromate and Bromide Ions
Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate...
Effects of Molecular Oxygen and pH on the Adsorption of Aniline to Activated Carbon
This paper examines the influence of molecular oxygen and pH on the adsorption of aniline to F-300 Calgon Carbon. Molecular oxygen increased the adsorptive capacity of GAC for anilines...
The Evaluation of Empty Bed Contact Time on the Biodegradation of Pentachlorophenol using an Anaerobic GAC Fluidized Bed
The objective of this research is to evaluate the effects of decreasing the empty-bed contact time (EBCT) on pentachlorophenol and its intermediates utilizing an anaerobic granular activated...
NCASI Experiment Related to Validation of Equilibrium Partitioning (EP) Theory
A review of NCASI's technical studies related to evaluating equilibrium partitioning (EP) theory as it is commonly applied in regulatory setting is presented. Although interim results...
Activated Carbon as a Catalyst for Polymerization of Phenolic Compounds
Previous studies by the principal investigator showed that the increase in the adsorptive capacity of activated carbon for phenolic compounds can be attributed to polymerization (oxidative...
Plain flooding: near field and far field simulations
The paper deals with the problems met in the attempt of simulating the plain submersion produced by a levee breaking in the inertia dominated region (near field), scaling with the typical...
Finite Element Algorithms for Modelling Flood Propagation
The paper details the numerical solutions adopted in the TELEMAC-2D code that solves the shallow water equations. The numerical choices have been driven by the need for computational efficiency...
Object-Oriented Finite Volume Dam-Break Model
This paper is devoted to Object-Oriented analysis and design techniques to two computational modules in the field of dam-breaking. The C++ Object-Oriented...
New Methods for Modelling Dam-Break Wave
Recent developments in numerical analysis for hyperbolic equations have led to new methods which solve shallow water equations including complementary equations for hydraulic jumps. An...
Two-Dimensional Dam-Break Flow Simulation in a Sudden Enlargement
The paper presents the use of a two-dimensional depth averaged mathematical model for an unsteady dam-break flow simulation in a sudden enlargement. Continuity and two momentum equations...
Free surface flow modelling on a complex topography
The aim of this paper is to describe the different construction stages and the validation of a free surface flow model on a complex topography. This model is based on the two dimensional...
Using the SedBed Monitor to Measure Bed Load
An acoustic distance measuring device (SedBed Monitor) was developed to accurately measure bed surface transects in a sediment and water recirculating flume. From these transects the rate...
