Reliability of Model Prediction for Pump and Treat Strategies
For the remediation of aqueous phase plumes extending over large areas simulation models are often used to predict the response of the aquifer system and the contaminant concentrations...
Methods for Designing Hydraulic Aquifer Remediation Techniques
This paper reports on recent research to develop methods for accommodating uncertainty in designing hydraulic remediation systems for contaminated aquifers. The methods rely respectively...
Statistical Analysis of Ground Water Quality Data
The Resource Conservation and Recovery Act (RCRA) requires owners and operators of hazardous waste facilities to utilize design features and control measures that prevent the release of...
Adaptive Control of Groundwater Hydraulics
Adaptive control has been extensively applied in industrial settings for the control of unknowns systems, systems with uncertainty in the parameters. The approach is recursive, the response...
Management of Subsidence in an Urban Environment
Houston, Texas is the fourth largest city in the United States and with its metropolitan area included, comprises a population of almost four million people. Large quantities of groundwater...
Ground Water Management in the Memphis, Tennessee Urban Area
In 1887, the first known water well was placed in the aquifer which presently supplies almost 100% of the water used by the Memphis Urban Area (MUA). Since that time, the MUA has developed...
The Managemet of Storm Water Runoff Associated with Industrial Activity
Section 405 of the Water Quality Act of 1987 mandates that municipal and industrial storm water discharges are point sources of water pollution and are subject to regulation under the...
Stormwater Quality Issues for Jefferson Parish
Jefferson Parish has a unique set obstacles to overcome in the operation of the drainage system. Situated in a coastal area and surrounded by water, the area has been developed through...
Source Identification and Ranking of Wet Weather Discharges in an Urban Area
A study has recently been completed to characterize the pollutant loadings to the Providence River, RI during wet weather conditions. A total of 11 land based sampling stations including...
Evaluation of Stormwater and CSO Impact on Portland's Columbia Slough
A team of consultants studied the impacts of stormwater and combined sewer overflows on an urban drainageway to determine if increased beneficial stream uses were attainable. Planning-level...
A Simulation to Noise Barrier
The problem related to noise barrier is simulated by a still, single frequency, three dimensional sound source located within two parallel screens with rigid back walls. The solution of...
Numerical Modeling of Pollutant Transport in Estuaries
A robust numerical solution to the pollutant transport phenomenon in an estuary is presented. The fractional step algorithm is employed to split the physical process into convection step...
Microscopic Modeling of Shear Strength of Contaminated Soils
The degradation of shear strength of soils due to prolonged contamination of soils is an emerging problem. The experiments conducted at New Jersey institute of Technology showed a gradual...
Penetration Testing for Groundwater Contaminants
Recent advances in penetration testing technology have produced a variety of new penetration devices to measure groundwater conditions. This paper describes two specially designed devices;...
Reliability Analysis for Time of Travel in Compacted Soil Liners
Time of travel through compacted soil liners is difficult to predict because numerous factors confound the analysis. In this paper, the influence of spatial variability and uncertainty...
Effects of Hurricane Hugo On Water and Wastewater Systems of the Charleston Commissioners of Public Works
Hurricane Hugo had a major impact on the operations of the Charleston Commissioners of Public Works in their effort to provide safe water and wastewater service to their customers. Through...
Citizen Participation in Regional Planning Efforts
During the past 4 decades the formal role of citizens has become increasingly more apparent under changing legislative mandates. This paper examines citizen participation in developing...
The Dispersion of Ocean Outfall Plumes: Physical and Biological Dynamics
The discharge of municipal wastewater into the coastal ocean through large ocean outfalls is an important component in managing sewage wastes generated by heavily populated urban areas...
Moored Systems for Time Series Observations of Bio-optical and Physical Variability in the Coastal Ocean
Recently, multivariable moored systems (MVMS) have been developed to study the ecology and physics of the upper ocean. Concurrent MVMS measurements provide time series of beam attenuation...
Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...
