Question
With the aid of a well labelled diagram, describe how a river braid is formed.
Answer
- Along this stage the river is flowing sluggishly at low velocity because of the gentle gradient.
- The river therefore deposits its heavy load on its bed.
- As the deposits accumulate, they form shoals which eventually grow into alluvial islands which raises the river-bed blocking the smooth flow of water.
- The river then becomes subdivided into channels or distributaries in its attempts to flow around the obstacles. This channels are known as river braids.
