Juvenile Fish Separator Design
Separation by size of downstream migrant juvenile salmonids at hydroelectric projects in the Columbia River basin is an integral part of transportation and bypass programs. However, separation...

Regional Groundwater Management with Health Risk Assessment
A regional groundwater system may have several areas which are contaminated with organic chemicals. In general, the objective of groundwater management is to supply the demand for water...

Optimization of Soil Vapor Extraction System Design
Soil vapor extraction is a cost-effective technique for the removal of volatile organic compounds (VOCs) immobilized in the unsaturated zone. The design of a soil vapor extraction system...

Effect of Surface Water and Ground Water Interaction on Atrazine Transport to Pumping Wells
High concentrations of agricultural chemicals in flood waters have been reported in many Midwestern rivers and streams. The public water supply wells of a number of riparian communities...

Use of Artificial Neural Networks for Agricultural Chemical Assessment of Rural Private Wells
The detection of agricultural chemicals in rural private wells has prompted for numerous studies at regional, state, and national levels. A principal concern arises from the fact that...

Simulation of Unsaturated Zone Virus Transport Adjacent to Municipal Wells
The EPA proposed groundwater disinfection rule for municipal wells would allow exemptions if, among other options, the necessary virus source setback distance could be maintained to provide...

Beneficial Aspects of Flood and Rain in Countries Where the Drinking Water is Naturally Contaminated with Fluoride Where Fluorosis is a Major Public Health Problem
Floods, although considered destructive, have beneficial aspects too. This report is about one such instance where flood waters are considered extremely beneficial in countries where drinking...

Effects of Ignoring Well Losses on the Specific Capacity Function
This paper combines these equations with the traditional step-drawdown equation to generate a more realistic relationship among discharge, specific capacity, and drawdown. Under both confined...

Experiences in Cleaning Up the Influence of Oil Spill on the Water Bodies
Experiences in cleaning up the influence of oil spill on water bodies of Komi Republic (European part of Russian North) and Dagestan Republic (North Caucasus) was generalized. In both...

Anaheim State-of-the-Art Water Treatment Plant—Six Years from Conception to Completion
After six years of intensive planning, budgeting, pilot testing, design, and construction, the City of Anaheim, California, has successfully completed the modifications to the 15 mgd Lenain...

Conjunctive Water Use Transforms a California Desert
An area doing multi-billion dollar recreational and agricultural business in the Southern California Sonoran desert owes its existence and well being to two things—wise water planning...

Use of δ¹8O and δD to Define Seawater Intrusion
On the basis of previous studies, more than 60 km² of upper aquifer system underlying the Oxnard Plain was believed to be intruded by seawater. Recent work has shown that there are sources...

Economic Impact of Managing Sea Water Intrusion
Sea water intrusion into a coastal aquifer may result from continued over extraction of the aquifer. In many coastal communities, sea water intrusion has led to artificial recharge programs...

Adhesion Kinetics of Fuel Oil #6 and Oil-in-Water Emulsions on Marine Sediments under Turbulent Mixing Conditions
Oil spilled in the marine environment is subject to a great variety of physical, chemical and biological processes, which determine its ultimate fate in the aquatic environment. Many of...

Simulation of Dilute Gas-Solid Flows in Horizontal Channels

Modulated Waves in Porous Media Saturated by Liquid and Gas

Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...
