Abstract

This paper presents a case study of recent vertical accretion on a fluvial terrace of the Upper Mississippi River, within the Sny Magill Unit of Effigy Mounds National Monument. Two independent methods are presented to estimate recent vertical accretion rates : one is based on Cs 137 analysis of sediment samples, the other is based on observed flood deposit thickness and magnitude frequency analysis. The projected accretion rates and time to burrial are subjected to large uncertainties because of environmental change in the watershed, including recent trends toward increasing flood stages and decreasing suspended sediment loads
