Large-scale bedforms in the Platte River downstream from Grand Island, Nebraska; structure, process, and relationship to channel narrowing
K.D. Crowley
1981, Open-File Report 81-1059
The Platte River channel in Nebraska, especially downstream from Grand Island, is characterized by large, periodic, and geometrically distinct bedforms called macroforms. Macroforms have dimensions commensurate with the width and depth of the channel and are emergent at all but the highest flow stages. The encroachment of vegetation on macroforms...
