Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "A recently-developed geometric model and associated computerized predictive methodologies designed to evaluate the impact of persistent changes in the ambient water level on the areal extent of marshlands were tested by a consideration of shoreline marshes in the Great Lakes basin. Historical airborne data dating from 1935 to 1985 and collected in a quasi-continual manner over reaches of Georgian Bay and the North Channel in Ontario, Canada were used, along with recorded values of ambient water levels during this period to compare the predicted marsh acreages of the conceptual mathematical model with the actual marsh acreages as measured from the aerial photography"--Abstract.
