Synopsis

This book offers a detailed examination of the erosion and recession rates of the glacial till bluffs along the Illinois Lake Michigan shore. Beginning with a historical overview of the formation of the bluffs during the Pleistocene era, the author presents data collected from vertical and oblique aerial photographs, topographic maps, lake surveys, and field measurements to assess temporal bluff-line changes and determine the impact of high lake levels on bluff erosion. The book also explores the role of bluff characteristics, including bluff height, slope angle, and the presence of protective structures, in determining erosion rates. The author discusses the concept of an erosion threshold, whereby erosion rates increase rapidly when lake levels exceed a certain threshold, and the time lag between lake level changes and bluff erosion or stabilization. The book concludes by highlighting the significance of these findings for understanding bluff erosion processes and developing effective shore protection strategies, particularly in the context of ongoing high lake levels.
