 Some minor watercourses are included in the list, especially if they are named as 'river'- such examples may be labelled (m).For simplicity, they are divided here by the coastal sections within which each river system discharges to the sea.In the case of the rivers which straddle the borders with Scotland and Wales, such as the Border Esk, Tweed, Dee, Severn and Wye, only those tributaries which lie at least partly in England are included.
