A riverbank is the land that borders a river. It can be made up of various materials, such as soil, sand, or rocks, and plays a crucial role in the ecosystem. Riverbanks help to control erosion, provide habitats for wildlife, and support plant growth. They are often important for human activities, including agriculture and recreation. Riverbanks can vary in shape and size, depending on the river's flow and surrounding landscape. Some riverbanks are steep and rocky, while others are gentle and sandy. They can also be affected by seasonal changes, such as flooding or drought, which can alter their appearance and function.
