Thesis advisor: Noah Snyder / Rivers impounded by dams experience morphological changes that provide an opportunity to calculate reservoir sedimentation rates and relate them to watershed land-use history. In April 2023, 10 sediment cores were collected from 5 locations in Lake Seminole, Georgia. Analysis of loss on ignition (LOI), bulk density, elemental concentrations, and short-lived radionuclide geochronology aided in completing the following research objectives: correlating short and long sediment cores, determining whether the pre-dam sediment surface was reached at each location, measuring the sedimentation rates in the Chattahoochee and Flint arms of the reservoir, and evaluating the characteristics of each core in the context of its location and the history of Lake Seminole. This research explores how differences in river management, land use, and upstream geology in the watersheds have contributed to sedimentation differences in the Chattahoochee and Flint Rivers. / Thesis (BS) — Boston College, 2024. / Submitted to: Boston College.
