Why does a river flow faster on the outside of a meander? As in any process, the random places where the water is able to travel faster start eroding more material causing meanders to grow toward the side of the river that is moving faster and eroding. Erosion narrows the neck of the land within the meander and as the process continues, the meanders move closer together. Over time this deepens the river bed and creates steeper sides which are then weathered. It is produced as a watercourse erodes the sediments of an outer, concave bank (cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. That's why we keep our work free. Take a photo of ameanderand tag us @usgs_yes #findafeature or send it to us at usgs_yes@usgs.gov.

The position of the curves changes over time. Meanders that form oxbow lakes have two sets of curves: one curving away from the straight path of the river and one curving back. The river flow is diverted by an obstruction allowing the river to do lateral erosion work. Over the course of fewer than 20 years, its path crawls back and forth, carving out deeper and deeper curves before cutting them off and starting over. The meander becomes an oxbow lake along the side of the river. Thus the curvature of the pathway of river water flow increases, and the shape of the meander changes over time. Which process results in the widening of the floodplain of a meandering stream? The water deposits sediment on the inside of the channel. A meander is when water flows in a curvy, bendy path, like a snake. Erosion narrows the neck of the land within the meander and as the process continues, the meanders move closer together.
