    The influence of vegetation and root density on erosion for Three Streams in Minnesota
    (2013-08) Underhill, Benjamin Lawrence
    Streambank erosion is a growing concern in Minnesota as hydrologic conditions continue to change throughout the state. Plant root anchoring and surface protection from vegetation play a role in reducing erosion. The Rosgen Bank Assessment for Non-point source Consequences of Sediment (BANCS) method of erosion prediction uses both root density and surface protection to estimate the resistance of a streambank to erosion. In order to understand how different types of vegetation can influence parameters within the BANCS system thirty sites were selected in the Glacial Lake Plain, Glacial Till, and Loess regions. Root sampling and vegetation surveys revealed no correlation between root density and erodibility factors from the BANCS system. Data from this study can assist restoration efforts in these regions in order to improve or refine current practices, reduce erosion and improve water quality.
