Soils and Subsurface GPR Imaging of Fluvial Terraces in the Lower Chippewa River Valley, WI.

Abstract

Little detail is known about the late Quaternary geomorphic history of the Upper Mississippi River and its major tributaries. However, the Lower Chippewa River Valley (LCRV) landscape suggests a complex history of Late Quaternary fluvial aggradation and downcutting. The primary objective of this research is to determine if ground penetrating radar (GPR), soil information, and optically stimulated luminescence (OSL) dating can be used to construct a testable chronostratigraphic model of LCRV fluvial terraces.
