Abstract

This report is intended to examine the ecological changes due to mixing in shallow water bodies. Physical, chemical, and biological changes are reported in literature. A literature search revealed the range of mixing nodes or processes. Assessment of ecological changes due to mixing by boating activities had been evaluated in a research project supported by the environmental Protection Agency and conducted at Florida Technological University. The examination of changes due to mechanical mixing on lake ecology simulated in fifty-five gallon drums indicated the sensitivity of such parameters as total Kjeldahl nitrogen, conductivity, pH, temperature, and dissolved oxygen. Problems of reproducibility and simulation are inherent in transporting sediments and water samples from a natural environment to an isolated barrel test. Even though care was taken to insure similar initial conditions for all water quality parameters in all of the drums, differences were recognized. The useful information from a pilot study of this nature comes f r o m the relative comparison of each drum before and after mechanical stirring.
