Bathymetric Survey of Barmouth Rail Viaduct

28th July, 2020

Our dedicated survey vessel Investigator has recently returned from a survey programme on the Welsh coast including a detailed bathymetric survey of the Barmouth Rail Viaduct (Barmouth Bridge).

Survey works were completed in two phases :

  1. High resolution laser scanning at low water
  2. High resolution multibeam echo sounder (MBES) survey at high water

The resultant integrated model provides our customer with the highest level of confidence in bathymetric output ensuring certainty in critical design works. The bed morphology is rather complex as a result of the draining Mawwdach  Estuary, the presence of the rail viaduct and recent marine depositional changes resultant from storm activity.
