Dr. E. Arthur "Art" Bettis of the University of Iowa's Department of Geoscience will outline the processes that formed the landscape of the Mississippi River valley during the last glacial period and over the past 10,000 years. Bettis will also discuss why bottomland restoration scenarios should incorporate existing information about the valley’s geomorphology to develop cost-effective projects and best management practices.
His teaching and research focus on landscape evolution during the past 2 million years. He pursues interests in the long-term behavior of eolian, fluvial and glacial systems and the impact of human activities on the landscape. His recent research involves the Homo erectus peopling and occupation of island Southeast Asia, stratigraphic and sedimentological studies of Midcontinet U.S. loess depositional systems, and the application of alluvial lithostratigraphy in stream management and restoration.
