Development of Data Quality Indicators for Indoor Air Pollution Measurements
Indoor air quality measurements pose a unique problem for the application of traditional Quality Assurance/Quality Control approaches. The lack of reference methods and materials in some...
Design of Final Covers for Landfills
Final covers or caps are incorporated into a completed landfill to limit the amount of moisture percolation through waste materials. A properly designed final cover system provides the...
Special Water Treatment in New Jersey
The New Jersey Department of Environmental Protection (NJDEP) performed a study on 'special water treatment'. The main goal of the project was to assess in detail...
Integration of EPA Guidelines Air Quality Models with Human Exposure/Risk Estimation Procedures
Techniques, based on dispersion models which are currently available, for performing population and maximum individual exposure and risk assessments due to ambient air emissions are described....
Removal of Radon and Uranium from a water supply
The removal of Radon and Radium from drinking water with the help of granulated activated carbon (GAC) adsorption was investigated. A packed bed column was used for the purpose. It has...
Models of Organics Transport Through Soil Columns
A mathematical model is proposed for the transfer of organic solutes in soil. Two cases are considered namely transport of non-adsorptive solutes and transport of adsorptive solutes. Comparative-study...
Health Effects,Risk Assessment and Guidance for Indoor Radon
Unlike many inorganic elements, radionuclides have no nutritional value. Radionuclides are carcinogenic and uranium is also known to be non-carcinogenic as well. This paper is primarily...
Treatment Facilities and Costs for the Removal of Radon from Ground Water Supplies
Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower...
Current Status of Flue GasDesulfurization in the United States
Flue gas desulfurization (FGD) systems have been in existence in the United States for only 17 years but they have made a tremendous impact in the operation of utility plants. At present,...
Engineering Methodology for Delineating Debris Flow Hazards in Los Angeles County
Utilizing historical and field data, elementary geomorphology and simplified hydraulics of debris flows, a mapping strategy has been developed. The delineation procedure includes defining...
Flood Risk Below Steep Mountain Slopes
Alluvial fans spread at approximately the critical hydraulic slope below apexes at canyon mouths. Periodic torrents that rage out of the canyons are devastating at the apex and have diminishing...
Debris Flows and Hyperconcentrated Streamflows
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that...
An Evaluation of Sediment Resuspension Parameterizations
The recent attention to managing surface water toxic substances has resulted in a number of modeling approaches, all of which to a great or lesser extent require accurate treatment of...
On the Ship's Waterways Passing Through Bridges
This paper reports on a study of bridge openings that serve as waterways, in view of the analysis of ship collision accidents. For the purpose of this study, cases of ship collision accidents...
Port Infrastructure Program in Mexico
In Mexico the policies, guidelines, goals and methodologies refering to transport, are the responsibility of the 'Secretaria de Comunicaciones y Transportes'...
Reservoir Sedimentation and Desilting in Taiwan
The island of Taiwan is infested with numerous flashy streams with steep slopes and huge sediment loads, thus, the major reservoirs have experienced heavy sediment deposit. The encroachment...
A Proposed Desilting Reservoir System in Taiwan
The paper discusses the design of a desilting system for Nanhwa reservoir, in which the reservoir is divided into two bays; water flows into the forebay for sedimentation and then over...
Sediment Penetration in Lakes as a Result of Dredged Material Disposal and River Sediment Loads
Pollutant transport within the coastal boundary layer is highly sensitive to the vertical current structure and to the magnitude of the vertical current, especially during upwelling and...
Sedimentation Processes in Hydrosystems, Numerical-Empirical Modeling
This paper presents the results of a newly developed computer simulation model for studying the sedimentation processes in a variety of hydrosystems. The most effective numerical methodology...
Sedimentation in the All-American Canal
During the planning for the All-American Canal, by the U. S. Bureau of Reclamation as part of the Boulder Canyon Project, works were designed at the head of the canal to remove between...
