Calculating discharge energies needed to transport largest boulders within eskers

Abstract

One main sediment transport feature within glaciers is eskers created by water from melting glacial ice. During times of rapid melt the amount of sediment that can be transported is at a maximum as well as the size of grains that can be transported. From the remnants of eskers I looked at these maximum flow events. The areas of investigation have been the northwestern portion of Wisconsin and the northeastern portion of Minnesota. These esker remnants are being investigated to find the unusually large grains infrequently transported during times of maximum discharge, and with that, find the maximum amount of energy in eskers.
