Effects of Solute Transport Processes on In-Situ Denitrification for Nitrate Control in Ground Water
This paper discusses the effects of solute transport mechanisms on the effectiveness of biodenitrification in the subsurface environment. The only solute transport processes apparently...

The Potential Use of Genetically Engineered Microorganisms in the Remediation of Environmental Pollution
Naturally occurring microorganisms express a broad range of metabolic activities which are being successfully applied to the field of bioremediation. Genetic engineering will enhance such...

Influence of Soil and Sediment pH and Redox Conditions on Degradation of Toxic Organics
The presence of toxic organics in soil and sediments has raised concern over persistence and bioaccumulation. In the absence of oxygen, microbial degradation of toxic organics proceeds...

Modeling of Wetland Hydrodynamics and Transport in Coastal Louisiana
Modeling of hydraulics and transport of large wetland systems poses critical decisions between resolution of the complex geometry of a wetland and the testing required to meet study goals....

Issues and Challenges Facing the Effective Delivery of Scientific Visualization
The availability of economical hardware and software products for scientific visualization has stimulated implementation of scientific visualization within high performance computing environments....

Visualization of a 3D Model of Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic and water quality model (WQM) of the Chesapeake Bay and its major tributaries has been developed by the US Army Engineer Waterways Experiment...

GIS Visualization Techniques in Surface Water Resource Planning
Geographic information system (GIS) computer graphic displays of surface water resource conditions provides a means for valuation-by-visualization (VBV) of alternate plans. GIS display...

Measurements to Calibrate Suspended Sediment Model for Adsorbed Contaminant Transport Study of North Fork Holston River, Virginia
A daily suspended sediment (SS) and mercury transport model was developed for a 25-mile reach of the North Fork Holston River below Saltville, Virginia. Daily streamflow measurements;...

Animation of Automated Space Construction
This paper presents a discussion of Three-Dimensional Computer Animation as applied to the evaluation of Lunar/Mars construction. A number of applications for this type of tool are introduced....

3D Computer Modeling & Animation for Marketing of Project Services
Three-dimensional (3D) computer modeling and animation are increasingly being utilized in the Engineering and Construction industry for the marketing of project services. Like 2D, 3D modeling...

Integration of CAD and Material Control
The purpose of this paper is to address the relationship between CAD (Computer Aided Design) drawings and the material control software. Computer generated drawings have the ability to...

Coastal Sediments
This proceedings, Coastal Sediments '91, contains more than 180 full papers delivered at a specialty technical conference of the...

Nutrified Sludge
A new biological treatment process, Nutrification, enables a wastewater treatment plant to remove phosphorus from influent water at an operating and maintenance cost 35% less than that...

Measurement of Wave-Induced Turbulent Flow Structures Using Digital Image Sequence Analysis
The turbulent flow in water close to the wavy wind-stressed water surface has been examined quantitatively in a large circular wind-water tunnel with a flow visualization method using...

Airborne Remote Sensing of Breaking Waves with Implications for Gas Exchange
It is shown that airborne remote sensing can potentially relate gas mixing effects within a temporally evolving breaking wave to relectivity changes, and can identify the intensity of...

Mercury Behavior in a Wastewater Sludge Incineration Process
The Western Lake Superior Sanitary District (WLSSD) in Duluth, Minnesota utilizes solid waste as fuel to incinerate wastewater treatment sludge, conserving energy resources while reducing...

Stochastic Responses of Lifeline Systems Under Seismic Excitations
A wave superposition model is proposed to predict the field motion on the basis of the seismic records obtained from a strong motion array. By assuming the ground motion to be a homogeneous...

Inductive Loop Detection/Testing with DSP Techniques
Vehicle traffic control is recognized as an effective way to relieve mounting traffic congestion in large urban areas across the country. The most common method of vehicle detection is...
