River bends, also known as meanders, are natural curves or loops in a river's path. They form as water erodes the outer banks and deposits sediment on the inner banks, creating a winding shape. This process can take many years and is influenced by factors such as the river's speed and the landscape it flows through. These bends play a crucial role in the river's ecosystem. They provide diverse habitats for various species, including fish and birds. Additionally, river bends can help reduce the speed of water flow, which can minimize erosion and improve water quality by allowing sediments to settle.
