These areas were identified for the purpose of the first Preliminary Flood Risk Assessment under the Flood Risk Regulations 2009 using guidance produced by the Welsh Government to identify areas where flood risk is an issue for greater than 5000 people. The Flood Risk Areas were first identified in 2011 until being replaced in 2018 by the Cycle 2 Flood Risk Areas.

Ardaloedd Perygl Llifogydd Cylch 1 yw'r cymunedau hynny yng Nghymru lle mae'r peryglon llifogydd mwyaf sylweddol yn bodoli o lifogydd dŵr wyneb yn unig (o ddŵr wyneb ffo, dŵr daear a chyrsiau dŵr cyffredin). Nodwyd yr ardaloedd hyn at ddiben yr Asesiad Cychwynnol o Fygythiad Llifogydd cyntaf o dan Reoliadau Perygl Llifogydd 2009 gan ddefnyddio canllawiau a gynhyrchwyd gan Lywodraeth Cymru i nodi ardaloedd lle mae perygl llifogydd yn broblem i fwy na 5,000 o bobl. Nodwyd yr Ardaloedd Perygl Llifogydd am y tro cyntaf yn 2011 hyd nes iddynt gael eu disodli yn 2018 gan Ardaloedd Perygl Llifogydd Cylch 2..
