Ceredigion Coastal Level, Rainfall and Storm Report
Adroddiad Lefel, Glawiad a Stormydd Afon Teifi
This report focuses on coastal and estuarine monitoring for Ceredigion, using data sourced from the West Wales Nutrient Management Board system and Natural Resources Wales. Coastal/tidal stations are prioritised by default; river and rainfall series can be shown as needed for context. For further details and access to live levels, visit the Natural Resources Wales River and Sea Levels website.
Mae'r adroddiad hwn yn defnyddio data monitro a gasglwyd o system Bwrdd Rheoli Maetholion Gorllewin Cymru a Chyfoeth Naturiol Cymru. Mae data glawiad a lefel afon ar gyfer yr ardal ehangach—gan gynnwys mesurydd glawiad Afon Rheidol—wedi'i gynnwys yn y dadansoddiad dalgylch Teifi er mwyn cyflawnrwydd. Mae'r adroddiad wedi'i optimio i leihau maint y ffeil tra'n cynnal clirrwydd gweledol. Am ragor o fanylion a mynediad i ddata byw, ewch i wefan Lefelau Afonydd a Môr Cyfoeth Naturiol Cymru.
