The Humber is a large tidal estuary on the east coast of Northern England. It is formed at Trent Falls, Faxfleet, by the confluence of the tidal rivers Ouse and Trent. From there to the North Sea, it forms part of the boundary between the East Riding of Yorkshire on the north bank and North Lincolnshire on the south bank. Although the Humber is an estuary from the point at which it is formed, many maps show it, erroneously, as the River Humber.

The Ythan Estuary is the tidal component of the Ythan River, emptying into the North Sea 19 kilometres (12 mi) north of Aberdeen, Scotland. The estuary’s tidal action extends a 7 kilometres (4.3 mi) inland and has characteristic widths of between 250 metres (820 ft) and 780 metres (2,560 ft). Besides the tidal channel there are interfaces to the upland dunes including mudflats, sand beaches and shingle flats. Reaches of salt marsh occur, but they are primarily near the Waterside Bridge and the mouth of the Tarty Burn, a small tributary river. Based upon the habitat of the moorland bordering the east of the Ythan River near the mouth, this estuary is the most significant coastal moorland in the northern United Kingdom.

Afon Cefni is one of the major rivers on the island of Anglesey, Wales. It is 16.9 kilometres (11 mi) long. The river starts at the Llyn Cefni in the centre of the island and then runs south through the county town of Llangefni. Just north of the A55 the river turns and flows south-west. It passes through the flatlands of the Malltraeth Marshes, where the river course was altered in 1824, creating a canal-like straight stretch. This part of the river and the surrounding marshes, part of which is a RSPB reserve, are frequented by a variety of wetland birds which in their turn are preyed on by falcons, hawks and harriers. A cycle trail follows the straightened course of the river as it flows through the marshes.
