Wayne State University Theses
Large-scale watershed land use changes, including urbanization, have resulted in accelerated soil erosion and sediment accumulation rates, which in turn have posed a threat to the longevity and productivity of a majority of the aging dams in the mid-western United States. In this study, we collected and analyzed 3 sediment cores each from two dams from the Mid-western United States: Webber Dam in Michigan and Goshen Pond Dam in Indiana. Cores were analyzed for 137Cs and 210Pb to establish chronology, as well as concentrations and isotopic composition of organic carbon and nitrogen to investigate the land use changes as preserved …
