Summary

An extreme flood in 2016 caused widespread culvert blockages and road failures across northern Wisconsin, including extensive damage along steep tributaries and ravines in the Marengo River watershed. Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss of wetland storage, and valley-side mass wasting. In 2020, a pilot study was begun to map and classify ephemeral and perennial streams and wetlands in terms of their susceptibility to fluvial erosion hazards. This study combines rapid geomorphic field assessments of river corridor erosion and coupled sediment and debris delivery with mapping geomorphic [...]

Purpose

This dataset contains the results of 15 geomorphic assessments completed October 2020 as part of a pilot study evaluating the susceptibility of streams in the Marengo River watershed to fluvial erosion hazards. Included in the dataset are geomorphic and habitat field data, photos of assessment sites, and estimations of annual erosion for each site.
