The lowest reaches of the Esk are in England but most of the river is in Scotland whilst a short section is followed by the England/Scotland border. Tributaries of the Esk which are wholly in Scotland are omitted from this list but may be found at List of rivers of Scotland.
The Dee and most of its tributaries arise in Wales. Though a section of it passes through England, it passes into Wales once again before discharging into the Irish Sea via the Dee estuary. For other rivers entering the Irish Sea and Cardigan Bay from Wales, see List of rivers of Wales. Only those tributaries of the River Dee which flow wholly or partly in England are listed here - for a complete list of the rivers and watercourses of the Dee catchment see List of rivers of Wales.
All further upstream tributaries of the Dee are wholly in Wales.

This section includes all rivers entering the Bristol Channel and the sea off the northern coasts of Devon and Cornwall which is referred to variously as the Southwest Approaches or Celtic Sea.
Rivers Severn and Wye
The lowermost Wye forms the boundary between England and Wales. Only those tributaries of the River Wye which flow wholly or partly in England are listed here - for a complete list of the rivers and watercourses of the Wye catchment and for other rivers entering the Bristol Channel from Wales see List of rivers of Wales.
All further upstream tributaries of the Wye are wholly in Wales.

The Humber is often referred to as the River Humber though the name is unusual insofar as it is an entirely tidal stretch of water formed as the Rivers Ouse and Trent combine at Trent Falls.
All rivers entering the North Sea between Spurn Point at the mouth of the Humber and Redcar, Cleveland. This section includes the entire North Sea coast of the traditional county of Yorkshire.
