Answer:
Flood plain, Alluvial fan, estuary and delta were the depositional landforms.
Explanation:
Water eroded the landform through hydraulic action, corrosion, corrasion and attrition. Water deposited their silts and eroded material at the old stage of the river side. In old stage their amount of water and velocity are decreased, so they deposits their fragments. Flood plain is formed when river course cross their embarkments and overflow the river. Estuary and delta are the formed at the mouth of the river. Delta is the triangular shaped landform to deposit the silt which is highly fit for rice cultivation.
