Other forms: riverbanks
A riverbank is the raised land at the edge of a river. Sit on the riverbank, the far riverbank, erode the riverbank.
The outside of a bend erodes and the inside builds up, which is how a river slowly moves across its valley and why a riverbank is never quite where the old map says. Trees along one hold it together with their roots.
