Accretion (coastal management)

Source: Wikipedia, the free encyclopedia.

Accretion is the process of coastal sediment returning to the visible portion of a beach or foreshore after a

sustainable
beach or foreshore often goes through a cycle of submersion during rough weather and later accretion during calmer periods.

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.
