As wave pass across the shallowing profile of the shelf to beach face they interact with the sediment surface and transformed, producing a series of hydrodynamic zones aligned approximately parallel to the shoreline. The sedimentary facies is determined for each hydrodynamic zone. We propose the sedimentary facies model for storm dominated shelf which is illustrated from the Middle Miocene coarse-grained sedimentary rocks in Northern Fossa Magna region. These sedimentary facies considered to have been distributed in the margin of a fan delta system, where the coarse grained sediments are mainly transported by wave and nearshore currents.
