The Flood Map shows the areas across Wales that could be affected by flooding from rivers or the sea. It also shows flood defences and the areas that benefit from them. Flood Map is designed to raise awareness among the public local authorities and other organisations of the likelihood of flooding and to encourage people living and working in areas prone to flooding to find out more and take appropriate action. The Flood Map includes several layers of information, this layer is: Flood Zone 3, which is NRWs best estimate of the areas of land with a 100 to 1 (or greater) chance of flooding each year from rivers or with a 200 to 1 chance (or greater) of flooding each year from the sea.

Mae'r Map Llifogydd ar gyfer Cynllunio yn cefnogi polisi cynllunio Llywodraeth Cymru ar berygl llifogydd a dyma'r man cychwyn ar gyfer ystyried perygl llifogydd yn y system cynllunio. Mae'n rhoi syniad o ba dir sydd mewn perygl o lifogydd gan afonydd, y môr a dŵr wyneb a chyrsiau dŵr bach, gan ystyried effeithiau newid yn yr hinsawdd dros y ganrif nesaf. Y Map Llifogydd ar gyfer Cynllunio yw'r set ddata allweddol i hysbysu a llywio penderfyniadau ynghylch datblygiad yn y dyfodol. Mae'r Parthau Llifogydd yn y Map Llifogydd ar gyfer Cynllunio yn dangos y peryglon anniffynedig o lifogydd o afonydd, y môr ac o ddŵr wyneb a chyrsiau dŵr bach. Mae Parth Llifogydd 3 yn arddangos rhychwant y llifogydd o: afonydd gyda siawns o 1% (1 mewn 100) neu fwy o ddigwydd unrhyw flwyddyn, gan gynnwys lwfans ar gyfer newid yn yr hinsawdd. y môr gyda siawns o 0.5% (1 mewn 200) neu fwy o ddigwydd unrhyw flwyddyn, gan gynnwys lwfans ar gyfer newid yn yr hinsawdd. Dŵr wyneb a chyrsiau dŵr bach gyda siawns o 1% (1 mewn 100) neu fwy o ddigwydd unrhyw flwyddyn, gan gynnwys lwfans ar gyfer newid yn yr hinsawdd. Caiff y Map Llifogydd ar gyfer Cynllunio ei arddangos mewn dwy ran, sef golwg sylfaenol a golwg fanwl. Yn yr olwg sylfaenol, dangosir y perygl llifogydd o afonydd a'r môr fel haen wedi'i huno. Yn yr olwg fanwl, caiff y perygl llifogydd ei rannu yn ffynonellau unigol. Yn y ddwy olwg, dangosir y Parthau Llifogydd ar gyfer dŵr wyneb a chyrsiau dŵr bach ar wahân.

Other infrastructure, including bridges, culverts, engineered channels and bypass channels, and embankments (e.g. railway or road embankments) that are not flood defences, is included in all modelling and mapping of flood zones.
