Hail Concepts
Hail, the product of vigorous deep convection, requires those same conditions that are conducive to the development of thunderstorms. These conditions include water vapor, especially in...

Effects of Dissolved Air Flotation Hydraulic Loading Rate on Water Treatment Performance

Nothing Wasted
Anoxic gas flotation (AGF), a patented system for anaerobic digestion of organic slurry waste, can recover as much as 85% of the phosphorus and 23% of the nitrogen in slurry waste, while...

Monitoring Dissolved Oxygen and Total Dissolved Gas in Tailraces

Total Dissolved Gas in the Near-Field Tailwater of Ice Harbor Dam

Prediction of Dissolved Gas Concentration Downstream of a Spillway

Design of Spillway Deflectors for Ice Harbor Dam to Reduce Supersaturated Dissolved Gas Levels Downstream

The Effect of Climatic Change on Hydrologic Variables
There has been increasing concern about the threat of global warming affecting the earth's climate. This warming scenario, called the greenhouse effect, is believed to be...

Climate Change: What the North American Water Engineer Should Know
Long-range forecasts of future global warming have been made based on the increase in carbon dioxide and trace gases in the air from human activities. Potential changes which would especially...

Water Vapor Effects on the Corrosion of Steel

Adsorption Technology for Mercury Control in Flue Gases

Prediction of Dissolved Gas Supersaturation Below Spillways

Implementation of Dissolved Air Flotation Technology

In-situ Extraction of Lunar Soil Volatiles
Techniques for their recovery and utilization of the potentially valuable solar-wind elements embedded in the lunar regolith have been proposed. In order to acquire quantities of 3He...

Living in Space
Living in space will be the key project for the survival of the human species in the future. The world is becoming more polluted, suffering under the lack of living space, and if people...

A Gas Sampling System for Withdrawing Humid Gases From Deep Boreholes

Observations on the Growth of an Internal Boundary Layer with a Lidar Technique
The distribution of atmospheric water vapor across a step change in surface humidity (dry-wet) was observed by a Lidar measurement technique under neutral atmospheric stability condition....

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...

Columbia River System Operations — Water Quality Assessment
In mid-1990, the U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, and Bonneville Power Administration embarked on a Columbia River system operation review. Ten technical work...

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...
