Cynllun Rheoli Traethlin
Asesiad ar raddfa fawr o'r risgiau sy'n gysylltiedig phrosesau arfordirol yw'r Cynllun Rheoli Traethlin, ac mae'n helpu i leihau'r risgiau hyn i bobl a’r amgylchedd datblygedig, hanesyddol a naturiol. Mae prosesau arfordirol yn cynnwys patrymau'r llanw, uchder tonnau, cyfeiriad tonnau, a'r ffordd mae'r traeth a deunyddiau ar wely'r môr yn symud. Mae'r Cynllun Rheoli Traethlin yn pennu cyfeiriad y polisi strategol ar gyfer rheoli arfordiroedd ac yn nodi'r dulliau mwyaf cynaliadwy o reoli'r risgiau i'r arfordir yn y tymor byr (Cyfnod 1: 0-20 mlynedd), y tymor canolig (Cyfnod 2: 20-50 mlynedd) ac yn yr hirdymor (Cyfnod 3: 50-100 mlynedd). Nodir cyfres o bolisïau dewisol, a chânt eu neilltuo i 'unedau polisi' ar gyfer pob cyfnod o'r Cynllun Rheoli Traethlin. 'Uned polisi' yw darn o arfordir y mae polisi rheoli traethlin ar wahân yn berthnasol iddo. Diffinnir unedau polisi yn ôl ardaloedd arfordirol sydd â nodweddion tebyg o ran prosesau arfordirol ac asedau mewn perygl ac y gellir eu rheoli'n effeithlon. Mae pedwar opsiwn polisi ar gael ar gyfer Cynlluniau Rheoli Traethlin: Cynnal y llinell: uchelgais i adeiladu neu i gynnal amddiffynfeydd artiffisial fel bod llinell y draethlin yn cael ei chynnal. Gall hyn gynnwys cynnal neu newid safon yr amddiffyniad. Symud y llinell: drwy adeiladu amddiffynfeydd newydd ar yr ochr o'r amddiffynfeydd gwreiddiol sy'n wynebur môr. Ni ddefnyddir hwn yn aml, ac mae'n gyfyngedig i unedau polisi lle ystyrir adfer darn sylweddol o dir. Nid oes unrhyw unedau polisi yng Nghymru lle neilltuwyd yr opsiwn i symud y llinell. Adlinio a reolir: drwy ganiatáu i'r draethlin symud yn ôl ac ymlaen yn naturiol, ond gan reoli'r broses er mwyn ei chyfeirio mewn mannau penodol. Dim ymyrraeth weithredol: pan nad oes unrhyw gynllun i fuddsoddi mewn amddiffynfeydd na gweithrediadau arfordirol, pa un a oes amddiffynfa artiffisial wedi bodoli yn y gorffennol ai peidio. Gall y dull rheoli arfordirol ar gyfer darn penodol o arfordir newid o'r sefyllfa bresennol pan na fydd polisi o bosibl yn ymarferol mwyach nac yn dderbyniol dros gan mlynedd. Felly, gall cyfuniad o bolisïau gael eu cynnig dros oes y Cynllun Rheoli Traethlin. Mae'r set ddata’n nodi pa Gynlluniau Rheoli Traethlin ail genhedlaeth sy'n berthnasol i ran benodol o arfordir Cymru a'r polisïau a neilltuwyd i unedau polisi sy'n ymwneud â'r ardal benodol honno. Haen aml-linell o ddata gofodol yw'r set ddata hon, sydd ar gyfer arfordir Cymru yn unig.

This dataset was created to provide a strategic overview map; as a consequence, it was created at a national scale of 1: 250,000. This means that the definition of the breakpoints and the accuracy to which the SMP lengths reflect the 'coastline' is suitable for strategic level use only. Consideration should be given as to whether it should be replaced by a more accurate representation. More detailed representations of the SMP boundaries may be available at Local/Regional level within the SMP documents.
SMP costing information contained within the GIS layer is at a broad scale and indicative only. This data is not available for all policy units and was inserted as part of the original data. This data layer would not be appropriate to support any detailed costings work, or for identifying planned capital expenditure.
This dataset may contain hyperlinks to websites operated by other parties. We do not control such websites and we take no responsibility for and will not incur any liability in respect of their content. Our inclusion of hyperlinks to such websites does not imply any endorsement of views, statements or information contained in such websites.
INFORMATION WARNING: Users should refer to the SMP2 documents for the definitive policies, if any errors are identified following the publication of this edited data layer in January 2019 please contact opendata@naturalresourceswales.gov.uk .
