What are 2 land forms created by river deposition?

Two landforms created by river deposition are deltas and alluvial plains. Deltas form at river mouths where sediment accumulates as the river meets a larger body of water, creating a triangular landform. Alluvial plains, on the other hand, are flat areas adjacent to rivers that are formed by the deposition of sediment during floods, enriching the soil and making these regions fertile for agriculture.
