There is a report today that the whole flow of the Afon Lliedi has disappeared into a sinkhole in Llanelli.
I don't know the area at all, but the site in Llanerch appears to be on the Swansea member of the Pennant Sandstone. Although there is limestone far beneath, perhaps a more like explanation is drainage into old coal workings.
