What is river meandering?
River meandering is the natural process where rivers or streams create winding, curved paths across their floodplains. This occurs due to the complex interactions among water flow, sediment transport, and the erodible nature of riverbanks.
Faster flow on the outer edges of bends erodes the bank, while slower flow on the inner edges leads to sediment deposition, gradually forming curves. Over time, these processes create a serpentine, winding river path.
The dynamic equilibrium between erosion and deposition continuously shapes the river, leading to its characteristic meandering course. This ongoing balance results in the river’s sinuous route as it adapts to the changing conditions of flow and sediment distribution.
