Watershed Hydrogeology Lab graduate student Brock Freyer has spent the last two years learning deeply about the hydrology, geomorphology, and sedimentology of the Upper Mississippi River System, as well as learning to use some sophisticated GIS techniques for 3-D analysis of topographic data. This week he is presenting the results of his work: “Effects of river management & sediment supply on island evolution in Pool 6 of the Upper Mississippi River, southeast Minnesota” at the Upper Midwest Stream Restoration Symposium. Brock is speaking in a session on Large River Restoration. Brock will be defending his M.S. thesis sometime in late spring.
