A new research paper by State Geologist Keith Schilling and Iowa DNR collaborators, Calvin Wolter and Jason Palmer, reports, for the first time, the extent of severe streambank erosion occurring in Iowa’s rivers and streams.

The paper, published in Journal of the American Water Resources Association, suggests that over 35,200 km of streambanks may be severely eroding, or approximately 41% of all third- to sixth-order streambanks.
