The sloping land alongside a river or stream, forming the sides of the watercourse channel. These areas are shaped by erosion and deposition processes and often support unique riparian vegetation.
Compound word from 'river' (Middle English, from Old French 'riviere') and 'bank' (Old Norse 'bakki' meaning slope or hillside). The term naturally evolved to describe the elevated edges of waterways.
Riverbanks are dynamic boundaries that constantly change - the outside curves of meanders erode away while the inside curves build up with deposited sediment, causing rivers to literally migrate across landscapes over time! Many ancient civilizations built their cities on riverbanks for water access, but had to constantly adapt to the changing positions of their rivers.
