SUMMARY:Lake Michigan water-level changes and their impacts on shoreli
 nes and shoreline property owners\, Chaos & Complex Systems Seminar\, 
 Dave Mickelson\, UW Department of Geology
DESCRIPTION:The Great Lakes are close to or exceeding record high lake
  levels. A major concern along many Great Lakes shorelines is what is 
 happening now and what might happen in the future to beaches\, and blu
 ffs above the beach. In response to nearshore and beach erosion at the
  base of the bluff under high lake-level conditions\, the lower part o
 f the bluff steepens and becomes more unstable. This instability typic
 ally migrates up the bluff face through time and the position of the b
 luff top eventually recedes\, threatening any structures that have bee
 n built on the bluff top. I will discuss a qualitative comparison of 2
 007 and 2018 low-level oblique airphotos of the shoreline from Door Co
 unty to the Illinois State Line. A primary aim of this study was to ev
 aluate changes on the beach and lower bluff that might predict the lik
 elihood of future bluff-top recession.
