摘要：

In the study described, the effect that dredging has on lake water temperatures and vertical mixing was analyzed by simulations with a modified version of the Minnesota Lake Temperature model. The simulation yields daily, 12 hourly vertical water temperature profiles, and graphs 12 hourly mixed layer depths, daily surface and bottom temperatures, and seasonal isotherm contours. The model was used to determine to which depths the lakes would have to be dredged to produce only one seasonal summer stratification which would suppress vertical phosphorus flow and therefore reduce the potential for algae growth. 19 refs.
