Lake Photoplankton Model with Destratification
Publication: Journal of the Environmental Engineering Division
Volume 108, Issue 5
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 artifical deepened surface layer.
