WebA meander is one of a series of regular sinuous curves in the channel of a river or other watercourse.It is produced as a watercourse erodes the sediments of an outer, concave bank (cut bank or river cliff) and deposits sediments on an inner, convex bank which is typically a point bar.The result of this coupled erosion and sedimentation is the formation … Web23 minutes ago · The Old Crow River meanders between Alaska and the Yukon in the Arctic.

WebMeandering rivers have a low gradient and thus slower flow, and usually have a high proportion of suspended sediment relative to the amount of bedload. A meandering river channel has curves that meander back and forth on a gently sloping floodplain. The flow speed in the channel varies with the geometry of the meanders.
