Sut ydyn ni'n monitro'r arfordir?

Mae’r map rhyngweithiol 3D isod (a ddarparwyd gan Brifysgol De Cymru) yn dangos model enghreifftiol a grëwyd o fesur y clogwyni ym Mhenarth. Trwy gymharu arolygon lluosog dros amser gallwn weld newidiadau a dysgu am y broses naturiol, eu graddfa a'u cyflymder, sy'n llywio ein penderfyniadau rheoli.

CoastSnap is a global citizen science project, that has recently been introduced to Wales by the Wales Coastal Monitoring Centre in partnership with Wales Coast Path. Your photos, taken at our installations, will help provide data regarding how climate change is impacting our beaches. There is a QR code at each site which takes you directly to the WCMC webpage where you can submit the photo. There are currently 18 sites across the Welsh coastline, including sites in every coastal County.
