Abstract Details

2021, Master of Arts, University of Toledo, Geography.
On February 15th, 2019, Indiana Dunes was elevated to the designation of a U.S. National Park. Along with this designation belongs the credo of the U.S. National Park Service, to conserve such places that are deem naturally, historically, or in so many words ecologically important by such means as will leave them unimpaired for the enjoyment of future generations. In 2019, the water level in Lake Michigan was trending above the long term recorded average, and as a result several locations in the National Park sustained damage due to erosion and inundation. Current water levels are receding, but predictions suggest that fluctuations from low to high periods will becomes more frequent and more severe. Acknowledging that this may be a certain outcome, requires a great understanding of the shoreline morphology within the National Park, especially considering such namesake features as the shoreline dunes. This study uses LiDAR data from an era of below average to a period of elevated water level for five areas of interest within Indiana Dunes National Park, to categorize levels of change in the near shore and beach regions, as well as quantify metrics of beach width change. Resulting in several Areas of Interest containing mixed values of dune elevation loss with some gain. Importantly identifying that Mount Baldy and Central Avenue Beach have majorly experienced dune elevation loss where iv gains were not seen based on dune migration. Additional findings include the massive inundation of beach area and substantial loss of foredunes at Portage Beach and the token area of Beach width gain at Beverly Shores (East).
