Abstract
The phytoplankton mass and available phosphorus during a destratification experiment, at Lake Calhoun, Minnesota, in 1972, are simulated by a numerical, multilayered, unsteady numerical model. A timescale of one day is used. The effects of surface mixed layer dynamics, PO4-P inflows from surface runoff, recycling of PO4-P from the sediments, available light, temperature, and mixing in the hypolimnion on phytoplankton productivity are analyzed. The model is used to: Hindcast the events of 1972; and explore the effects of other lake management alternatives such as the reduction of PO4-P from runoff, the elimination of phosphorus recycling, and the maintenance of an artificially deepened surface layer.
