Je was op zoek naar: ceuffos (Wels - Engels)

mae gennym broblem benodol yng nghorwen , lle mae ceuffos yn gorlifo bob blwyddyn
we have a particular problem in corwen , where a culvert floods every year

weithiau , nid mater o lanhau ceuffos yn unig ydyw ond mater o'i gwneud yn fwy
sometimes , it is not only a matter of cleaning a culvert but of expanding its capacity

felly , er enghraifft , os oes ceuffos sydd dan ddwr , neu ffordd sydd wedi diflannu , gallwch eu hadfer i sut yr oeddent o'r blaen
therefore , for example , if there is a culvert that is flooded , or a road that has disappeared , you can restore them to how they were before
