Description :
The purpose of this paper is to examine spatial variations in flood discharges in one major tributary to the Mississippi River drainage system. The Raccoon River basin has variable topography and land use, including some of the most intensely agricultural land in the United States. Extensive ditch networks and subsurface tile drain systems have been installed to enhance runoff and accelerate drainage. The AA. found that sites within and downstream of modified channels had higher magnitude floods than other comparably sized basins in the Racoon River basin and the upper Midwest for which data were available.
