Water Quality Model of the Chicago Waterway
In 1992, the Metropolitan Water Reclamation District of Greater Chicago (the District) developed a QUAL2E water quality model of the Chicago waterway and Upper Illinois waterway. The model...

Modeling DO-BOD Dynamics in Johor River Estuary, Malaysia, Due to Agro-Industrial Discharge
This paper presents a summary of a study on the dynamics of dissolved oxygen in a tidal reach of the Johor River due to the discharge of agro-industrial waste subject to freshwater flow...

Evaluation of Dissolved Oxygen and Nutrient Trends in the Houston Ship Channel from Historical Statewide Monitoring Data
Dissolved oxygen and selected nutrient trends in the Houston Ship Channels (Texas Water Commission (TWC) segments 1007, 1006 and 1005) during the period of 1969 through 1990 were evaluated...

Distribution of Chlorophyll-a and Influence factors in Dapengao
The Present Paper majority describes the distribution and annual variational characteristics of the content of chlorophyll - a in the waters of Dapengao, Daya Bay of Guangdong Province....

Water Quality Modeling of Lower Green Bay
The impact upon water quality of the planned expansion of a confined disposal facility (CDF) located in lower Green Bay was studied using numerical hydrodynamic and water quality models....

Density Fluctuations and Use of the Krypton Hygrometer in Surface Flux Measurements
The magnitude of the of the Webb et al. (1980) density corrections on water vapor fluxes due to the flux of sensible heat is examined in terms of the Bowen ratio. The correction due to...

Observations of Artificial Destratification
Artificial destratification using bubble plumes is one means whereby low dissolved oxygen in the hypolimnion of lakes and reservoirs may be averted. Temperature and DO were measured at...

Chatuge Hydroproject Aerating Infuser Physical Model Study
The Tennessee Valley Authority is investigating the feasibility of a dual purpose reregulation and aeration weir to increase the dissolved oxygen in water releases and to provide continuous...

Modeling Vertical Stratification in the Pamlico River Estuary Using Modern Hydrodynamics
A modern hydrodynamic model is applied to the Pamlico River estuary. Good agreement was obtained between measured and predicted water elevations and salinity distributions during the one...

Dissolved Oxygen Analysis for Hydropower Additions on the Illinois River

Assessing the Quality of Citizen Volunteer Monitoring
Total-error profiles and quality control charts are presented as quantitative techniques to determine acceptability of methodology and analyses for volunteer water quality monitoring programs....

Diffusion of Carbon Dioxide Through Layers of the Unsaturated Zone at Yucca Mountain
The estimation of diffusive transport of gases through tuffs is important in order to asses the Yucca Mountain as an environmentally safe and acceptable repository for spent fuel and high-level...

Organic Carbon Input in Shallow Groundwater at ÄSPÖ, Southeastern Sweden
The variation in carbon and oxygen isotopes in calcite fissure fillings and dissolved carbonate from shallow groundwaters has been examined at Aspo, southeastern Sweden. The shallow water...

Aeration Using the Howell-Bunger Valve

Modification of the Stilling Basin at Arthur R. Bowman Dam, Oregon to Reduce Dissolved Gas Supersaturation

Non-Traditional Water Quality Approaches

In-situ Release of Solar Wind Gases from Lunar Soil
A concept is described which has the potential to perform the in-situ heating of the lunar regolith in order to release the solar wind gases. The poor thermal conductivity of the lunar...

Environmental Aspects of Lunar Helium-3 Mining
Three potential detrimental effects of lunar 3He mining have been identified; visual changes, atmospheric contamination, and solid waste disposal....

Extraction of Potable Water from Urine for Space Applications
A regenerative technology capable of managing water and wastewater on-board long-term manned space platforms is essential if the Bush Administration's Space Exploration Initiative (SEI)...

3-D Particle Tracking for the New York Bight
This paper describes the development and testing of a three-dimensional particle tracking model for the New York Bight. A number of particle tracking options have been developed to predict...
