Accretion is the process of coastal sediment returning to the visible portion of a beach or foreshore after asubmersion event.[1] Asustainable beach or foreshore often goes through a cycle of submersion during rough weather and later accretion during calmer periods.[1]
If a coastline is not in a healthy sustainable state, erosion can be more serious, and accretion does not fully restore the original volume of the visible beach or foreshore, which leads to permanent beach loss.[1]
