silt
My alluvial island is formed primarily from silt. The barrier of silt is being washed away from the delta!
because it just is
Deltas are landforms formed at the mouth of a river where the river meets a body of water, such as a sea or ocean. Silt is a type of sediment that is commonly found in river deltas, as it is carried by the river and deposited in the delta. The accumulation of silt over time contributes to the growth and formation of delta landforms.
Silt is carried downriver on the fast currents until it reaches the slow to nonmoving waters, where the silt forms a delta, which collects more silt.
A delta forms the the mouth of a river that is carrying a silt burden. Probably named after the Greek capital letter Delta.
A landform formed at the mouth of a river that is deposited by silt is called a delta. Deltas typically have a triangular shape and are rich in nutrients due to the sediment deposited by the river, making them fertile areas for agriculture and wildlife.
