Nodweddion Arafu Dŵr Ffo 1% AEP WWNP - Cymru

Potensial Nodweddion Arafu Dŵr Ffo yw ein hamcangyfrif gorau o leoliadau lle mae llif uchel yn cronni ar draws yr arwynebedd tir neu mewn sianelau llai, lle gall fod yn bosibl storio dŵr dros dro a gwanhau llifogydd yn ystod llifoedd uchel. Mae'r set ddata wedi'i chynllunio i ddangos ardaloedd lle gellir targedu storio gwell. Mae'n seiliedig ar y setiau data Perygl Llifogydd o Ddŵr Arwyneb ac mae'n nodi ardaloedd o grynoadau llif uchel ar gyfer y mapiau dŵr arwyneb Tebygolrwydd Gormodiant Blynyddol 1%.


Nid yw'r data'n darparu gwybodaeth am ddyluniad, a all fod angen ystyried materion fel draenio rhwng digwyddiadau llifogydd. Mae'n bwysig nodi nad yw perchenogaeth tir a newid i berygl llifogydd wedi cael eu hystyried. Efallai bod gwaith adeiladu neu ddefnydd tir mwy diweddar yn y lleoliadau a nodwyd nag sydd ar gael.

Datganiad

The data does not does not provide information on design, which may need to consider issues such as drain-down between flood events. It is important to note that land ownership and change to flood risk have not been considered. Locations identified may have more recent building or land use than available. Further information on the Working with Natural Processes project, including a mapping user guide, can be found in the reports published here: https://www.gov.uk/government/publications/working-with-natural-processes-to-reduce-flood-risk JBA Consulting carried out the contract.
