Summary

This dataset contains the 10 most common geomorphon forms for an approximately 500 meter (m) reach of the Kalamazoo River upstream of Plainwell, Michigan (MI), in raster and polygon format. Geomorphons are a terrain analysis approach that identify 3-dimensional forms in a landscape based on comparison of the relative elevations of a central pixel to the pixels in its surrounding viewshed. The approach breaks down a landscape into it's component forms (flat, summit, ridge, shoulder, spur, slope, hollow, footslope, valley, and depression), which can serve as a basis for interpreting distinct hydrogeomorphic units and processes associated with them (Jasiewicz and Stepinski, 2013). Polygon features were developed from the original raster [...]

Purpose

Bathymetric and topographic elevation data were collected to characterize the geometry and geomorphology of a reference reach that is representative of less-disturbed conditions in the Plainwell-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. Geomorphons identify landforms in the channel and floodplain. They may be used to characterize the spatial scale, organization, and frequency of geomorphic forms in the reference reach, and thereby may be useful as a guide for the design and review of channel restoration plans.
