WebMeanders In the middle course the river has more energy and a high volume of water. The gradient here is gentle and lateral (sideways) erosion has widened the river channel. The river channel has also deepened. A larger river channel means there is less friction, so the water flows faster: As the river erodes laterally, to the right side then the

WebWhere is a meander formed? Meanders are formed in the middle course of a river.
