Which type of soil is typically deposited by streams during flood stages?

Alluvial soil is formed through the deposition of sediment by flowing water, particularly in floodplains and river valleys. During flood stages, streams overflow their banks and carry a mixture of sediments, which can include sand, silt, and clay. When the water recedes, these sediments settle and create alluvial deposits. This type of soil is often fertile and well-suited for agriculture due to the nutrient-rich materials it carries from upstream. Alluvial soils are characterized by their layered structure, which reflects the varying sediment sizes deposited over time, making them distinct from other soil types.
