What are the deep parts of a meander in a river called?

The deep parts of a meander in a river are called pools. Pools are characterized by deeper waters typically found on the side of the river bend where the flow is slower, allowing for sediment to settle out and deeper areas to form. This contrasts with other parts of the river, such as riffles, where the water is shallower and flows more rapidly over rocks and gravel. Understanding the dynamics of river meanders is important because they shape the river's path and influence the local ecosystem, sediment transport, and habitat availability. Pools play a critical role in providing habitats for various aquatic life, demonstrating how the physical characteristics of rivers can impact biodiversity.
