Alluvial features are landforms created by the deposition of sediment from rivers and streams. These sediments, often rich in nutrients, accumulate in floodplains, deltas, and riverbanks, shaping the landscape over time. Common alluvial features include alluvial fans, levees, and oxbow lakes, which are formed through the natural processes of erosion and sedimentation. These features play a crucial role in ecosystems and agriculture. The fertile soil found in alluvial areas supports diverse plant life and is ideal for farming. Additionally, alluvial features can influence water flow and habitat availability for various species, making them important for both natural and human environments.
