Harmonized glacial landform regions and noncontributing area calculations were used to assess stream network development over time on irregular, glacial topography. Existing statewide geology maps for the study area contained incongruities in detail and interpretations at state borders complicating analyses performed across state borders. Glacial landform region delineations divided the landscape into areas with similar topography, age, and geologic materials. Age was considered the primary factor for harmonization. The resulting map addressed issues in the existing maps and provided a continuous landform regions map for the analysis of drainage integration across the study area. As streams erode headward into the upland of these landscapes, upland depressions are drained and integrated into the network. Considering agricultural practices have altered hydrological processes in the study area, use of drainage density as a metric for natural stream network development is difficult. Assuming that drainage density increases proportionally with landscape age means we should also observe noncontributing area decreasing proportionally with age. Results of this study indicate that the trend of decreasing noncontributing area in the study area is not explained solely by age. Examination of the relationship with additional factors suggest that landscape development on complex glacial landscapes is explained by a combination of factors interacting. These results indicate the need for further analysis of glacial landscapes to determine the driving factors of landscape development.
