Wind Control of Algae Growth in Eutrophic Lakes
In eutrophic lakes, light and turbulent mixing near the water surface often controls the actual occurrence and disappearance of algal blooms. While nutrients provide necessary materials...

Presenting Trends in Lake Eutrophication
This technical note presents a procedure that was developed for defining probable trends in water quality in Skaha Lake, British Columbia, Canada, a lake that is becoming eutrophic. The...

Regional Analysis of Economic Activity, Resource Management and Lake Eutrophication: A Case Study of Itasca County, Minnesota

Nutrients and Aquatic Vegetation Effects
After eutrophication from natural and civilizational causes is explained, the term oligotrophication is defined as the (partial) reversal of the eutrophication process under the influence...

Stochastic Model of Dynamic Eutrophic Estuary
A stochastic model for a one-dimensional estuary has been formulated. It was found that with the addition of a single new parameter, a stochastic model can be built from its deterministic...

Deterministic Model of Dynamic Eutrophic Estuary
A stochastic model for a one-dimensional estuary has been formulated. It was found that with the addition of a single new parameter, a stochastic model can be built from its deterministic...

Response of Anabaena to pH, Carbon, and Phosphorus
The objectives were to study the roles of carbon and phosphorus in cultural eutrophication, and to investigate the observation that blue-green algal blooms are frequently associated with...

Rational Multivariate Algal Growth Kinetics
In general, bioassay results showing that the relationship between growth rates and nutrient concentrations that are applicable to mathematical models of the eutrophication process are...

Estimating Eutrophic Potential of Pollutants
Laboratory microcosms comprising approximately 7 l of lake water and 1 l of bottom mud with a species invasion pressure maintained by periodic addition of small quantities of fresh lake...

Nitrogen Losses From Alkaline Water Impoundments
Results of an investigation of gaseous ammonia nitrogen losses from alkaline water impoundments are presented. A method of field measurement of these losses is described and a comparison...

Predicting DO Variations Caused by Algae
Eutrophic environments are often dominated by planktonic algal populations (phytoplankton) which can cause diurnal variations in DO concentrations through respiratory activity and photosynthesis....

Measurement and Detection of Eutrophication
A fluorometric technique is described for measuring chlorophyll concentrations. The technique has application to any situation which requires the measurement of chlorophyll such as monitoring...
