The Wye river forms the boundary between England and Wales for part of its length. It is 215 km long. The River Dee forms the boundary between England and Wales for part of its length. It is 110 km long. But forming the boundary is separating England and Wales, not joining them.
The Severn river rises in the Cambrian Mountains of Powys, Wales then flows across the border and into England, then flows through Shropshire, Gloucestershire, and Herefordshire before forming an estuary between England and Wales. Does that count as joining the two countries? Taking the river as ending and the estuary beginning at Severn Beach, South Gloucestershire, the Severn is 354 km long.
You have to ask whether any river joins England and Wales. It is the sovereignty of the British Crown that joins them, and the authority of the Westminster Parliament.
