Finite Strain Consolidation for Vertical Drains
Consolidation equations for vertical prefabricated drains which consider finite vertical strain of the soil are derived. Estimated consolidation times are shorter when finite soil strain...
Performance of Wick Drains Installed by Vibration
Settlement and piezometer data from construction of fills on Route I-291 in South Windsor, CT is analyzed for total settlement and coefficient of consolidation. The results are compared...
Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...
Consolidation of Ground Reclaimed by Inhomogeneous Clay
A large amount of prefabricated band drain was installed to improve the ground reclaimed by soft soils at the enlargement project of the Tokyo International Airport. By analyzing data...
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...
Assessing Roughing Filtration Design Variables
Rural communities are affected by the surface water treatment rule and are looking for inexpensive filtration options which are easy to operate and maintain. This paper evaluates roughing...
Biodegradation of Phenanthrene in Sand Columns in the Presence of Nonionic Surfactants
The effects of three nonionic surfactants on phenanthrene (C14H10) removal and mineralization by aerobic bacteria...
Artificial Recharge of Aquifers
Artificial groundwater recharge is a means of replenishing groundwater supplies with surface water which might otherwise be lost. Artificial groundwater recharge has also been used to...
Ozonation as an Alternative to Mandatory Filtration
The increased levels of required disinfection along with more stringent disinfection by product control as outlined in the Surface Water Treatment Rule and the Disinfectant-Disinfection...
Heavy Metal Removal Using Peat/Wetland Treatment
The purpose of this paper is to present an overview of the mechanisms and application of a peat/wetland treatment system for heavy metal removal from wastewater. The mechanisms involved...
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...
A Gap in the Surface Water Treatment Rule: The Watersheds
Watershed control is required by the Surface Water Treatment Rule of the 1986 Amendments to the Safe Drinking Water Act for systems that do not provide filtration. Where filtration is...
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...
Predicting the Impact from Significant Storm Events on a Hazardous Waste Site
The Stringfellow Hazardous Waste Site is a former Class I industrial waste disposal facility located near the community of Glen Avon in southern California. In response to community concerns...
A New Set of Equations for Very Shallow Water and Partially Dry Areas Suitable to 2D Numerical Models
When a 2D model is used to compute the flood propagation over an initially dry area some difficulties arise due to the changes in the computational domain as large parts of it are flooded...
A Computerized Open Channel Flow Measurement Device
This is a technical information paper with the intention of introducing a new product. It is not the intent of the author to use this as a marketing tool. However, it is the intent to...
Transport Process of Surface Liquid Spills
A mathematical model simulating the scenarios of surface liquid spills is presented in this paper. This model describes the advance front and recession curves of surface spills based on...
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...
Nonlinearity and Free-Surface Flow
The Dupuit-Forchheimer (D-F) assumption is commonly considered a viable design criterion for water resources projects and, consequently, Darcy law is used to determine the locus of free...
