Description: Many of the fields in the attribute table of this shapefile are the results of running ArcGIS plugin Planform Statistics (Lauer and Parker, 2008) on the channels' traced banklines. Many fields have null values (typically 0) where banks could not be traced. The attribute table fields are:dFrmMNR_m (m) distance from the confluence of the Blue Earth and Minnesota Riverswidth (m) channel width where traced streambanks exist. These points were measured on the Blue Earth and Watonwan, but were calculated on the Maple and Le Sueur following the relationship between width and upstream area in Gran et al., 2013.chanElv (m) the elevation of the channel centerline from the 3m DEMChanSlp channel slope, averaged over a moving 6km long reachupstrmA_km (km^2) sampled from a flow accumulation raster created from a 30m resolution DEMc (m/a) channel migration rate, measured using Planform Statistics and the traced banklines.
