Abstract Details

2022, Master of Science, Miami University, Geology and Environmental Earth Science.
Stream restoration is a method used to try to return function to impaired streams and has become a billion-dollar industry in the U.S. A key limitation to stream restoration success, however, is an insufficient understanding of what streams in the Midwest were like prior to European settlement. By combining historical maps and aerial imagery with surficial geologic mapping; past stream channel pattern, controls on channel pattern, channel migration zones, and changes in fine sediment loads were identified for Four Mile Creek in southwestern Ohio. Gravel-bed, laterally active anabranching or meandering streams were dominant prior to European settlement. Wetland deposits, which are associated with some types of anabranching streams, were not prevalent in the mapping area during pre- or post-European settlement time periods. Channel migration rates appear to have declined by around 50% since the early 1800s and the percentage of mud in stream channels significantly increased after European settlement (p=0.010). This study and the associated map provide a baseline understanding of what the natural stream channel pattern and fine sediment loads were in the Midwest prior to anthropogenic disturbances in order to help inform stream restoration project designs.
