The Fabric Dyers' Use of Recycled Water
Tuftex Industries manufactures both residential and commercial carpets. As a Division of Queen Carpets, Tuftex is the largest carpet manufacturer on the West Coast and part of the fourth...
Dye Concentration Distribution in a Turbulent Wake Using Video Imaging Technique
Application of Video Image Processing in the Study of Environmental Flows
Full-Field Dye Concentration Measurement Within Saturated/Unsaturated Thin Slabs of Porous Media
This paper presents a full-field dye concentration measurement technique that extends our experimental capabilities to the measurement of transient dye concentration fields within steady...
Infiltration into Thick Unsaturated Alluvial Deposits: A Preliminary Study
An infiltration and dye transport study in an unsaturated alluvial deposit was conducted using a square flooding type infiltrometer over a 50 hour period. Red and blue dyes were added...
Variability of Hydraulic Response of Constructed Wetlands
Dye tracer studies using Rhodamine WT have been performed on two field scale subsurface flow wetland units for further improvement of secondary treated municipal effluent at Byron Bay...
Water-Level, Velocity, and Dye Measurements in the Chicago Tunnels
On April 13, 1992, a section of a 100-year-old underground freight tunnel in downtown Chicago, Illinois was breached where the tunnel crosses under the Chicago River, about 15 meters below...
Using a Dye Study for Defining Diffusion in a Water Quality Model
Tracer Study for C*t Compliance Evaluation
A tracer study was performed with a fluorescent dye, Rhodamine WT, to determine the actual disinfectant contact time for the 36-mgd Courtney Bend Water Treatment Plant near Independence,...
Gas Transfer Measurements on an Ice-Covered River
Wasteload allocation for existing and proposed pulp mills in the Athabasca River Basin of northern Alberta, Canada, necessitated measurement of the atmospheric reaeration rate, K2,...
Random Sheets, Random Strings, and Oceanic Dye Dispersion
In Situ Determinations of Dispersion and Transport Parameters at Piraquara De Fora (RJ)—Brazil, With Help of a Fluorescent Dye Tracer
This paper deals with 'in situ' determinations of the transport and dispersion parameters at Piraquara de Fora cove, near the site where the first Brazilian nuclear...
The Turbulent Wake of a Recirculating Eddy in Shallow Waters
The wake, created by injecting dye into the recirculating zone of a sudden lateral expansion in a shallow open channel, is examined experimentally for a range of bed-friction influence....
In Situ Measurement of Preferential Flow
An experiment was performed that quantifies the variability of flow paths in the vadoze zone. Bromide tracer and an organic dye, which has many of the same transport characteristics as...
Pesticide and Nitrate Movement Under Conservation and Conventional Tilled Plots
Carbofuran, alachlor, atrazine, nitrate and bromide (a tracer) were applied to plots with conventional and conservation tillage. During the early part of the growing season the conservation...
Use of Tracers in Sediment Transport Studies
Unsteady Mixing of a Buoyant Jet into a Reservoir
A buoyant effluent was dyed with fluorescent dye on two occasions to determine its mixing characteristics and flow path through a small hydropower reservoir located in south central Arkansas....
Fluorescent Tracer Mixing Experiments in Glenmore Reservoir, Calgary
Mixing studies using salt and dye as tracers were conducted in Glenmore Reservoir which is the major water supply for the City of Calgary, Alberta. The purpose of the studies was to find...
