The Roanoke River meanders across the coastal plain of eastern North Carolina. It is an important conduit for water, solutes, and sediments to the Albemarle Sound and also serves as a migration route for wildlife and transportation pathway for humans. Confederate soldiers built a blockage across the river during the Civil War to prevent Union troops from reaching the Weldon rail hub. Recently collected multibeam data indicates remnants of this blockage deposited on the river bed still influence the pattern of megaripples today.
