1. Meanders: These are winding, looping curves in a river's path. They form as a river erodes the outer bank of a bend and deposits sediment on the inner bank.

2. Oxbow Lakes: These are crescent-shaped lakes that form when a meander is cut off from the main river channel. This happens when erosion cuts a new, straighter path across the neck of the meander.

3. Floodplains: These are flat, fertile areas of land that are periodically flooded by a river. The floodwaters deposit sediment, making the land rich and suitable for agriculture.

4. River Terraces: These are step-like features that occur along the sides of a valley. They are formed when the river erodes downward, leaving behind the older, higher floodplain levels.

5. Deltas: These are triangular-shaped areas of land that form at the mouth of a river where it enters a larger body of water (like a lake or ocean). They are created by the deposition of sediment as the river's velocity slows down.
