river islands
Land amid currents
River islands are landmasses that form within rivers, created by sediment deposits or the splitting of river channels around higher ground.
They range from small temporary sandbars that shift with flooding to large permanent islands supporting vegetation and even settlements.
The picnic area on the river island was only accessible by boat.
Some river islands are ecologically significant, providing habitat for wildlife, while others become prime real estate in urban rivers.
