Hanes y morglawdd<\/h2>\n

[\/vc_column_text][vc_column_text]Mae Morglawdd Bae Caerdydd 1.1 cilomedr o hyd ac mae\u2019n mynd o ddociau Caerdydd yn y gogledd i Benarth yn y de. Arweiniodd y project adeiladu peirianyddiaeth sifil hwn at gorlannu\u2019r Bae, sydd \u00e2 dros 13 cilomedr o f\u00f4r o\u2019i flaen.<\/p>\n

Dechreuodd y cynllun gwerth \u00a3220 miliwn ym mis Mai 1994 a chafodd ei gwblhau ym mis Tachwedd 1999 \u2013 dyma oedd y prif gatalydd ar gyfer gwaith adfywio gwerth \u00a32 biliwn ar hen ddociau Caerdydd a Phenarth.<\/p>\n

Mae lociau a phontydd, llifddorau a llwybr pysgod yn rhan o\u2019r Morglawdd. Mae yno hefyd ardal wedi ei thirlunio, man agored cyhoeddus, lle gall y cyhoedd fynd am dro neu bicnic wrth edrych ar yr olygfa hyfryd tua\u2019r m\u00f4r a\u2019r bae mewnol.[\/vc_column_text][vc_column_text]<\/p>\n

Sut mae\u2019r Morglawdd yn gweithio?<\/h2>\n

[\/vc_column_text][vc_column_text]O gwmpas safle\u2019r Morglawdd, ceir byrddau gwybodaeth yn disgrifio\u2019r gwaith o ddydd i ddydd. Dyma fwy o fanylion ynghylch cydrannau unigol strwythur y Morglawdd:[\/vc_column_text][vc_tta_accordion style=”flat” shape=”square” color=”peacoc” active_section=”0″ no_fill=”true” collapsible_all=”true”][vc_tta_section title=”Ystafell Reoli\u2019r Morglawdd” tab_id=”1616430988413-9b4895e9-249a”][vc_column_text]Dyma ganolbwynt y gweithrediadau, ac mae\u2019n cael ei staffio 24 awr y dydd, 365 diwrnod y flwyddyn gan d\u00eem o weithredwyr, rheolwyr lociau a pheirianwyr. Yr ystafell yw\u2019r prif bwynt cyswllt ar gyfer cychod sy\u2019n hwylio i mewn i ac allan o Fae Caerdydd.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Lociau a phontydd” tab_id=”1616430988430-02af45e1-cd14″][vc_column_text]<\/p>\n

Mae tri loc ar y morglawdd, a phob un yn 40medr o hyd; mae dwy yn 8 medr o led ac un yn 10.5 medr o led. Maen nhw\u2019n caniat\u00e1u i gychod hwylio rhwng Aber Afon Hafren a Bae Caerdydd. Gall pob loc adael hyd at 10 llong o faint cyffredin drwyddo; mae croesi\u2019n cymryd rhwng 5 ac 20 munud, yn dibynnu ar y llanw.<\/p>\n

Mae gan bob loc bont wrthbwys sy\u2019n pwyso tua 88 tunnell. Gan fod ystod llanw\u2019r aber mor uchel, mae gatiau\u2019r loc yn mesur hyd at 16 metr o uchder i alluogi cychod i hwylio drwodd ar unrhyw gyfnod y llanw.<\/p>\n

Pan mae\u2019r lociau wedi cau, mae modd i gerddwyr, beicwyr a cherbydau basio dros strwythur y Morglawdd.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Mae pum llifddor yn rheoli lefel y d\u0175r yn y Bae. Defnyddir y llifddorau un ai i adael i lif o afonydd Taf ac El\u00e1i fynd i F\u00f4r Hafren neu i greu rhwystr i atal y llanw uchel rhag dod i mewn i\u2019r Bae. Gall dros chwarter miliwn litr o dd\u0175r yr eiliad lifo trwy bob d\u00f4r, sy\u2019n 7.5 medr o uchder a 9 medr o led.<\/p>\n

Mae\u2019r llifddorau\u2019n gweithio gan ddefnyddio gwybodaeth gan synwyryddion lefelau d\u0175r y Bae a\u2019r aber i bennu lleoliad y giatiau. Pan fo lefel d\u0175r yr aber yn uwch na\u2019r Bae, mae\u2019r llifddorau\u2019n cau i atal d\u0175r y m\u00f4r rhag llifo i mewn i\u2019r llyn d\u0175r croyw. Pan fo lefel d\u0175r yr aber yn is na lefel y Bae mae\u2019r llifddorau\u2019n agor i gynnal lefel y d\u0175r.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Mae\u2019r Morglawdd hefyd yn cynnwys llwybr pysgod pwrpasol i alluogi eogiaid a brithyll m\u00f4r i ddychwelyd i afonydd Taf ac El\u00e1i. Dyma un o\u2019r llwybrau pysgod mwyaf blaengar yn Ewrop, mae\u2019n cynnwys camer\u00e2u tanddwr ac offer symud a sain sy\u2019n cofnodi taith y pysgod ac yn adnabod rhywogaethau gwahanol.<\/p>\n

Mae\u2019r eog a\u2019r brithyll m\u00f4r yn silio ym mhennau uchaf afonydd Taf ac El\u00e1i yn y gaeaf. Pan mae\u2019r pysgod ifainc yng nghyfnod eu gwyniad, maen nhw\u2019n teithio i lawr yr afon ac i\u2019r m\u00f4r. Wedi rhyw ddwy flynedd, mae\u2019r pysgod, sydd bellach yn rai mawr, yn dod yn \u00f4l i\u2019r afon y ganwyd nhw ynddi ac yn \u00f4l i\u2019r safle silio i gwblhau\u2019r cylch. Mae rhai eogiaid o Afon Taf wedi teithio cyn belled \u00e2\u2019r Cefnfor Iwerydd, a hyd yn oed i arfordir gorllewinol yr Ynys Las cyn dod yn \u00f4l i Fae Caerdydd.<\/p>\n

Mae d\u0175r croyw yn llifo i\u2019r llwybr pysgod o\u2019r Bae ac ar hyd system o byllau a choredau, sy\u2019n caniat\u00e1u i bysgod nofio ym mhob cyfnod llanw, o\u2019r aber i\u2019r Bae. Mae\u2019r pysgod y tu allan i\u2019r Bae yn adnabod y d\u0175r croyw sy\u2019n llifo o\u2019r afon sy\u2019n gartref iddyn nhw, ac maen nhw\u2019n dod i mewn ar hyd y llwybr pysgod.<\/p>\n

Mae Awdurdod Harbwr Caerdydd yn monitro\u2019r llwybr pysgod er mwyn sicrhau ei fod yn gweithio\u2019n effeithiol. Ewch i\u2019n hadran Amgylchedd am fwy o wybodaeth.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
