How are oxbows and loess similar?

Oxbows and loess both show similarity as they both show the constructive power of erosion. An oxbow lake starts as a curve in a river. Oxbows are formed where the river often empties into another water body. A loess is a sediment which is formed by the accumulation of the wind blown silt.
