Where does the sediment come from?

Beach sediments can come from

  • cliff sources, for example Flamborough Head in Yorkshire

  • off shore bars of sediment, brought onshore by wave action

  • brought down by river systems, for example Morfa Harlech sand dune system in Cardigan Bay

  • relic sources from the last glaciation
