Segregation of Sediment During Deposition
A laboratory experiment was conducted to investigate the segregation of sediment during deposition. Sediment eroded from an upslope source area of Blount silt loam was introduced to a...
Depleted Uranium Migration in Stream Bedload Environment
The objective of this paper is to present results of a comprehensive hydrologic transport study, designed to assess potential surface water contamination, resulting from the release of...
Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
Discrete Particle Computer Methods for Modeling Granular Flow
Dense Slurry Flows
The Importance and Measurement of Cavitation Nuclei
Combustion Sources of Residential Air Pollution: An Overview
Combustion by-products are a major source of indoor air pollution and have been measured in homes at levels above typical outdoor concentrations, and at levels which approach or exceed...
Effect of Particle Size on Sludge Dewaterability
Using a modified Buchner funnel apparatus to measure specific resistance and a sequential centrifugation/filtration procedure to fractionate a sludge, it was possible to more precisely...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Some New Approaches in Certain Aspects of Cavitation Research
Analytical Modeling of Sediment Particle Lift-Up
Erosion and Sedimentation Processes in Irrigation
Soil erosion occurs when fluid in motion detaches and transports soil particles. Sedimentation occurs when the fluid transport capacity decreases. Both the hydraulic forces of moving water...
Particle Diffusion in the Atmospheric Surface Layer
Fluidization of Biomas Covered Sand Particles
The expansion behavior of the fluidized bed reactor support medium is important in its design and analysis. Steady state and dynamic behavior of fluidized bed expansion were compared with...
Benefits of Particle Size Management for Biological Wastewater Treatment
Particle size distributions in wastewater can be used to monitor and model the transformations that occur during wastewater treatment processes. Typical size distributions of organic contaminants...
Coagulation in Natural Waters
The hydrodynamics and chemistry of particle-particle interactions can control the transport of particles and of particle-reactive pollutants. In lakes, particle deposition is accomplished...
Physical and Chemical Behavior of Chrysotile Asbestos Particles in Natural Waters
The paper reports on research to develop a better understanding of the chemical behavior and the influence of surface chemistry on the physical behavior of chrysotile asbestos and other...
Reactive Transport of Suspended Particles
Monte Carlo simulation of the total probability density function for each constituent easily handles non-linear reactions and has a cost that increases only linearly with the number of...
Sedimentation of Waste Particles in Coastal Waters
Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition...
Brownian Coagulation in the Initial Mixing Region of a Buoyant Plume
The paper discusses reactive systems that share the following common phenomenon: their reaction is either controlled by both kinetics and diffusion, or fully by diffusion. It reports on...
