The sudden input of a large amount of sediment may create a new landform such as a delta, this can be seen in the Soufriere Hills, Montserrat 1996 in which a pyroclastic flow entered the sea from the Tar river valley, to form a shallow shelf for sediment to accumulate, creating a low energy coastal system.
