A total of 44 cross-sections were surveyed on the Le Sueur and Maple rivers, near Mankato, Minnesota in 2008 and again in 2015. The cross sections were initially measured in 2008 to support development of a watershed sediment budget (Belmont et al., 2011; Gran et al., 2011) and a numerical sediment routing model (Viparelli et al., 2014). The flood of record occurred in 2010, with several other large floods in subsequent years. So the cross-sections were repeated in 2015 in an effort to quantify morphological changes in the channel to inform development of a morphodynamic channel-floodplain model (Call et al., 2017). In each survey, a total of 20 bankfull cross-section surveyed on the Le Sueur River and another 24 cross sections were surveyed on the Maple River.
