Abstract

This study statistically compares certain morphometric characteristics of second order drainage basins developed on Pleistocene glacial surfaces of different ages and compositions. The morphometry of the basins was found to be partially controlled by the type and age of unconsolidated materials into which the streams are cutting. The analysis also suggests that the Iowan Erosional Surface is closely approximating a time-independent or equilibrium condition, while the other surfaces are in comparative disequilibrium.
