How does the water flow on the inside and outside of a river that is straight?

In a straight river, water flows uniformly along the main channel, with the highest velocity typically found in the center and just below the surface. On the outside banks, the flow can be slightly faster due to reduced friction, while the inside edges may experience slower flow and sediment deposition. This difference in velocity can lead to the formation of features like erosion on the outer banks and point bars on the inner banks. Overall, the flow is generally laminar, maintaining a consistent direction along the length of the river.
