Soil Erosion and Sediment Control From Highway Construction

Bruce Wilson, Department of Biosystems and Agricultural Engineering

November 16, 2004

Bruce Wilson, professor in the Department of Biosystems and Agricultural Engineering at the University of Minnesota, gave an overview of important issues in erosion and sediment control by using the construction of TH 23 located near Spicer, Minnesota as an example. This construction project will spend roughly $4 million on erosion and sediment control. A summary of research activities support by CTS was then presented, including field work on the effectiveness of erosion control blankets, a laboratory study on shear partitioning of vegetal elements, and computer model development to be used for risk assessment of different management options. Key features of the erosion certification program administered jointly by the University of Minnesota and Mn/DOT were also presented.
