Summary

This dataset contains topographic cross sections spanning the river channel, floodplain and valley walls from an approximately 15 kilometer (km) reach of the Kalamazoo River between the Trowbridge Dam and Allegan, Michigan (MI). One representative cross section was selected for each reference reach and located to be oriented perpendicular to the river channel and valley axis. Bankfull hydraulic geometry attributes and complexity metrics were calculated for each cross section, as were floodplain inundation dimensions for flow stages at multiples ranging from 0.9 to 2.0 of the bankfull depth. The cross section data were extracted from a digital elevation model (DEM) comprising topographic and bathymetric data for Area 5 of the Kalamazoo [...]

Purpose

This dataset was collected to characterize the geomorphology of reference reaches that are representative of minimally disturbed conditions in the Trowbridge Dam-Allegan stretch of the Kalamazoo River. The goal of the reference reach analysis is to inform river restoration designs and evaluations associated with dam removal projects by developing channel criteria that meet stakeholders' priorities for hydrologic connectivity, channel stability, and fish passage within the river/floodplain system. cross sections spanning the valley bottom allow for characterization of the topography of the channel and floodplain, computation of channel bankfull hydraulic geometry attributes, as well as floodplain hydrologic connectivity during a range of flood stages.
