Mae Ardaloedd sy'n Elwa ar Amddiffynfeydd rhag Llifogydd yn dangos ardaloedd Cymru sy'n elwa ar amddiffynfeydd rhag llifogydd sy'n amddiffyn rhag llifogydd o afonydd a'r môr. Mae'r ardaloedd a ddangosir yn elwa ar lefelau gwahanol o amddiffyniad rhag llifogydd a chydnabyddir hyn yn y dosbarthiad risg a ddangosir ar fap Asesiad Perygl Llifogydd Cymru. Mae'r ffin allanol ar gyfer yr Ardaloedd sy'n Elwa ar Amddiffynfeydd rhag Llifogydd wedi'i gosod ar y terfyn lle ceir risg isel o lifogydd o afonydd neu'r môr (h.y. yr ardal sydd siawns o 0.01%, neu 1 mewn 1,000, o gael llifogydd mewn unrhyw flwyddyn).

The data is not property specific and shows the benefit for a general area. This information is different to the previous Flood Map: Areas Benefitting from Flood Defences which only showed the benefit provided in the event of a river flood with a 1% (1 in 100) chance of happening each year, or a flood from the sea with a 0.5% (1 in 200) chance of happening each year. Not all flood defences and areas that benefit from a flood defence are shown. These will gradually be added as information becomes available.
