Tanner Bonham is AGL's newest graduate alum, having successfully defended his M.S. thesis entitled Hydraulic Geometry Relationships and the Development of Bankfull Regional Curves for Iowa Streams. Tanner's defense took place on August 12th. One key result of Tanner's research was the recommendation that urban (>10% impervious surface in the basin) and non-urban streams be treated separately in regional curves. He showed a statistically-significant increase in channel size (especially width and cross-sectional area) in urban compared to non-urban streams. Tanner's regional curves have already been incorporated into the latest version of the Iowa River Restoration Toolbox. Look for a journal article in the coming year providing more details.
Congratulations to Tanner Bonham on successfully defending his M.S.
