Summary

This is a polygon coverage of sand deposits from the 2011 Missouri River flood. The polygon coverages were compiled from classification of 26 multispectral SPOT (Système Pour l’Observation de la Terre) 4 and 5 satellite images colleted during October and November, 2011. The dataset covers 1,298 km of the Missouri River valley bottom from Gavins Point Dam in South Dakota to the confluence with the Mississippi River near St. Louis, Missouri. Dataset is described in: Alexander, J.S., Jacobson, R.B., and Rus, D.L., 2013, Sediment transport and deposition in the lower Missouri River during the 2011 flood: U.S. Geological Survey Professional Paper, 27 p. http://pubs.usgs.gov/pp/1798f/

Purpose

We assessed deposition of sand on the Missouri River floodplain as a measure of sediment-related geomorphic effects and damages. Sand deposition was compiled from multispectral satellite imagery collected October and November, 2011. SPOT (Système Pour l’Observation de la Terre) 4 and 5 satellites provided 26 10- and 20-m resolution multispectral images that covered the entire 811 miles (1,298 km) of the Lower Missouri River at a discharge that was entirely within the banks. Sand was mapped using supervised classification of each image, and confirmed by limited ield visits. Sandbars within the banks were excluded from the analysis. This method results in a conservative estimate of sand deposition because sand overlain by mud was excluded, and sand was undermapped when it was deposited in wooded areas. No attempt was made to relate sand area to volume; however, similar methods after the 1993 flood on the Mississippi River indicated that minimum detectable thickness of sand is on the order of 60 cm (Jacobson and Oberg, 1997).
