Alluvial deposition occurs when rivers lose energy and deposit sediment, forming fertile landforms such as deltas and floodplains. This process is crucial for creating rich agricultural areas and sustaining diverse ecosystems along river valleys.

Floodplains are flat areas of land next to rivers or streams that experience occasional or periodic flooding, often providing rich, fertile soil ideal for agriculture. They serve as natural buffers by absorbing excess rainwater and reducing the risk of floods in adjacent urban areas.

River valleys are geographic formations created by the flow of a river through a landscape, carving out a path over time, often creating fertile soil that supports rich biodiversity and human agriculture. They have historically served as cradles of human civilization, providing water resources, means of transportation, and fertile land for farming.
