Modelling the Effect of Verticl Flow-Developer on Ice Cover

Analysis of Reaeration Equations Using Mean Multiplicative Error

Implementation of Dissolved Air Flotation Technology

Effects of Climate Change on Water Quality
This research explores the potential effects of climate change on the quality of waters in lakes. Temperature and dissolved oxygen were considered the primary water quality variables due...

A Gas Sampling System for Withdrawing Humid Gases From Deep Boreholes

Interlaboratory Comparison of UO2 Dissolution Rates

Comparison of Uranium Dissolution Rates From Spent Fuel and Uranium Dioxide

In Situ Photothermal Deflection Spectroscopy of Uranium Dioxide Dissolution

Effect of Roughness and Thickness of Biofilms on External Mass Transfer Resistance
The effect of roughness and thickness of biofilms on the dissolved oxygen (DO) concentration boundary layer thickness (DO CBLT) and the external mass transfer process in a biofilm system...

Modeling Full-Scale Diffused Aeration Systems
The purpose of this research was to show the direct relationship of the oxygen mass transfer coefficient (KLaT)...

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....

A Coupled GIS-Water Quality Modeling System
A modeling framework is developed which uses a geographic information system (GIS) to perform many of the time-consuming tasks needed to set up and run a general water quality model. The...

Development of Transport Model for Groundwater Planning and Management in Taipei Basin
The objective of this paper is to develop a groundwater model for contaminant transport simulation. The transport model, in conjunction with the previously developed flow model, is used...

Macro-Roughness Effects on Stream Reaeration
The gas transfer coefficient is key to modeling dissolved oxygen levels in streams. Engineers commonly predict it as a function of mean flow depth, velocity, and slope. Large errors are...

Reservoir Sediment Removal: Hydrosuction Dredging
Hydrosuction dredging is a relatively little-known method of removing sediment deposits from reservoirs. The method is similar to traditional hydraulic dredging except the difference between...

Salinity and Dissolved-Oxygen Dynamics in a Wind-Driven Estuary
Water levels, near-surface and near-bottom salinities, and near-surface and near-bottom dissolved-oxygen concentrations were measured continuously in the Pamlico River estuary, North Carolina,...

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...

Agitation Dredging Environmental Study

An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...

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...
