Figure 4.—Typical pattern of soils and parent material in the Albaton-Percival-Sarpy and Albaton-Onawa-Forney associations on the channel belt and meander belt areas of the Missouri River floodplain. The flood basin consists of a natural levee and backswamp area and is the area between the meander 66
4th IUSS Soil Classification Conference <strong>Field</strong> Tour Guidebook belt and the loess hills in the uplands (fig. 5). Near the loess hills low gradient fluvial fan onlap the flood basin. The flood basin is a low relief that lacks distinct meander scars and obows. The backswamp of the flood basin may be lower than the adjacent meander belt. Low areas of the flood basin often display flood distributary patterns. Because it does not have meander scars and oxbows left behind from the meandering Missouri River, the flood basin has fewer surface features than the channel belt or the meander belt. Most of the flood basin is at a lower elevation than the meander belt, but the flood basin has been flooded less frequently than the meander belt. At the conjunction of the meander belt and the flood basin, the meander belt is cut deeper into the Missouri River Valley and leaves behind an area that acts as a natural levee that is higher in elevation than the remaining bottom-land areas of the Missouri River valley. The rarely flooded Keg and Salix soils are typical of the soils on this natural levee (fig 6). Because floodwaters have not crested this natural levee for hundreds or even thousands of years, the soils are more developed than those on the channel belt or meander belt areas of the floodplain. Flooding in the flood basin is mainly caused by flooding tributary rivers and streams. These have all been diked or channelized in order to reduce this occurrence. Taxonomically the soils in this area consist of Mollisolls which range from well drained to poorly drained.
