Version History for U.S. Geological Survey Scientific Investigations Report 2021–5114 Assessment of Runoff Volume Reduction Associated with Soil Amendments Added to Portions of Highway Median-Strip Catchments in Ohio, 2018–20 By Matthew T. Whitehead and G.F. Koltun ----------------------------------------------------- First posted online October 27, 2021 ----------------------------------------------------- Revised and reposted December 9, 2021, as version 1.1 The year range in the title was changed from 2018–2020 to 2018–20 everywhere in the report. The far-out value in the explanations of figures 4, 5, 6, 7, and 10 was updated to reflect that the value was ≥ 3 times the interquartile range beyond either end of box, not > 3 times the interquartile range. The definition of the corresponding symbol, ≥, was added to the figure captions of the affected figures. Table 7’s title had a wording change. “Differences in the empirical distribution functions or pre-best management practices” was changed to “differences in the empirical distribution functions of pre-best management practices.” Table 7 had six values that were bolded.
