Working with Natural Processes (WWNP) in Wales: Floodplain Reconnection Potential
Potensial Ail-gysylltu Gorlifdiroedd WWNP - Cymru

Working with Natural Processes (WWNP) Floodplain Reconnection Potential is our best estimate of locations where it may be possible to establish reconnection between a watercourse and its natural floodplain, especially during high flows. The dataset is designed to support signposting of areas where there is currently poor connectivity such that flood waters are constrained to the channel and flood waves may therefore propagate downstream rapidly.

Gweithio gyda Potensial Plannu Coetir ar Orlifdir Prosesau Naturiol (WWNP) yw ein hamcangyfrif gorau o leoliadau lle gall plannu coed ar y gorlifdir fod yn bosibl, ac yn effeithiol i wanhau llifogydd. Mae'r set ddata wedi'i chynllunio i ddangos ardaloedd o orlifdir nad ydynt eisoes yn goediog.


Mae'r wybodaeth a ddarperir yn seiliedig yn bennaf ar ddata wedi'i fodelu a data cyfyngiadau agored, ac felly mae'n ddangosol yn hytrach na phenodol. Efallai bod gwaith adeiladu neu ddefnydd tir mwy diweddar yn y lleoliadau a nodwyd nag sy'n cael ei nodi yn y data sydd ar gael. Mae'n bwysig nodi nad yw perchnogaeth tir a newid i berygl llifogydd wedi cael eu hystyried, ac efallai y bydd angen modelu effeithiau unrhyw blannu sylweddol.

The dataset is based upon the Risk of Flooding from Rivers and Sea probability maps, and identifies areas of low and very low probability that are close to a watercourse, but which do not contain residential property or key services. The areas may contain non-residential property so it is important to consider this and recent buildings or defences when considering floodplain reconnection. Locations identified may have more recent building or land use than available data indicates. It is important to note that land ownership and change to flood risk have not been considered, and it may be necessary to model the impacts of significant reconnection. 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.
