Editing River Severn (section)

==Tributary rivers==
Over its length, there are a large number of tributaries, but the three largest feeding the non-tidal river are the [[River Vyrnwy|Vyrnwy]], the [[River Teme|Teme]] and the [[River Avon, Warwickshire|Warwickshire Avon]]. The [[River Wye|Wye]], the [[River Avon, Bristol|Bristol Avon]] and the [[River Usk|Usk]] all flow into the estuarine section of the Severn. The main tributaries are described in sequence below.{{citation needed|date=May 2023}}

The first tributary of significance is the [[Afon Dulas, Llanidloes|Afon Dulas]], joining from the south immediately upstream of [[Llanidloes]], with the [[Afon Clywedog]] joining in the town. The [[Afon Cerist]], bolstered by the [[Afon Trannon]], and the [[Afon Carno]] join as left bank tributaries immediately upstream of Caersws. Mochdre Brook enters on the western edge of Newtown, followed by the Bechan Brook just northeast of the town. [[The Mule (river)|The Mule]] enters at [[Abermule]], and the [[River Rhiw]] east of [[Berriew]], followed shortly by the [[Camlad]] which rises above [[Churchstoke]] and by the Luggy Brook. The left bank Sylfaen Brook enters at [[Welshpool]], and the Bele Brook via the New Cut east of [[Arddlin]].

The River Vyrnwy, which begins at [[Lake Vyrnwy]], flows eastwards through [[Powys]], gathering the waters of the [[River Banwy|Banwy]], [[River Cain|Cain]] and [[River Tanat|Tanat]], before forming part of the border between England and Wales, and joining the Severn near [[Melverley]], Shropshire. The [[River Perry, Shropshire|River Perry]] joins on the left bank above [[Shrewsbury]], while both the [[Rad Brook]] and the [[Rea Brook]], which flows northeast from its source at [[Marton, Shropshire|Marton Pool]] near the Welsh border, join the Severn within the town. The left bank tributary, the [[River Tern]], after flowing south from [[Market Drayton]] and being joined by the [[River Meese]] and the [[River Roden, Shropshire|River Roden]], meets the Severn at [[Attingham Park]].

The [[River Worfe]] joins the Severn's left bank just above [[Bridgnorth]], before the Mor, Borle and [[Dowles Brook|Dowles]] brooks join on the opposite bank over the next few miles, the last-named draining [[Wyre Forest]]. The [[River Stour, Worcestershire|River Stour]] rises in the north of Worcestershire in the [[Clent Hills]], near St Kenelm's Church at [[Romsley, Worcestershire|Romsley]]. It flows north into the adjacent [[West Midlands (county)|West Midlands]] at [[Halesowen]]. It then flows westwards through [[Cradley Heath]] and [[Stourbridge]], where it leaves the [[Black Country]]. It is joined by the Smestow Brook at [[Prestwood (Kinver)|Prestwood]] before it winds around southwards to [[Kinver]], and then flows back into Worcestershire. It then passes through [[Wolverley]], [[Kidderminster]] and [[Wilden, Worcestershire|Wilden]] to its [[confluence]] with the Severn at [[Stourport-on-Severn]]. The [[Dick Brook]], Shrawley Brook and Grimley Brook enter on the right bank before the [[River Salwarpe]], which runs through [[Droitwich]] enters on the opposite (east) bank.

The River Teme flows eastwards from its source in [[Mid Wales]], straddling the border between [[Shropshire]] and [[Herefordshire]]; it is joined by the [[River Onny]], [[River Corve]] and [[River Rea, Shropshire|River Rea]] before it finally joins the Severn on the southern edge of [[Worcester, England|Worcester]]. Bushley Brook joins just upstream of the confluence of the [[River Avon, Warwickshire|Warwickshire Avon]] with the Severn at [[Tewkesbury]]. One of several Avons, this one flows west through [[Rugby, Warwickshire|Rugby]], [[Warwick]] and [[Stratford-upon-Avon]]. It is then joined by its tributary the [[River Arrow (Worcestershire)|River Arrow]], before joining the Severn. The rivers [[River Swilgate|Swilgate]] and [[River Chelt|Chelt]] also join the Severn's left bank, as do the [[Hatherley Brook|Hatherley]] and [[Horsbere Brook|Horsbere]] brooks, before it reaches Gloucester. The [[River Leadon]] enters the tidal West Channel of the Severn at Over, immediately west of Gloucester. The [[River Frome, Stroud|River Frome]] is the second significant tributary to enter the tidal stretch of the Severn, doing so at Framilode. Bideford Brook drains the easternmost part of the [[Forest of Dean]], entering the Severn estuary east of [[Blakeney, Gloucestershire|Blakeney]]. On the opposite (southeast) bank the flow of the [[River Cam, Gloucestershire|River Cam]] is usurped by the [[Gloucester and Sharpness Canal]] before reaching the estuary. [[Lydney Canal|The Lyd]] enters the west bank of the estuary at [[Lydney Canal|Lydney Harbour]], opposite the place where Berkeley Pill carries the waters of the [[Little Avon River]] into it. The final tributary before the Severn Bridge is the collection of streams which enter via Oldbury Pill.

The River Wye, from its source in [[Plynlimon]] in Wales ({{convert|2|mi|sigfig=1}} from the source of the Severn), flows generally south east through the Welsh towns of [[Rhayader]] and [[Builth Wells]]. It enters [[Herefordshire]], flows through [[Hereford]], and is shortly afterwards joined by the [[River Lugg]], before flowing through [[Ross-on-Wye]] and [[Monmouth]], and then southwards where it forms part of the border between England ([[Forest of Dean]]) and [[Wales]]. The Wye flows into the Severn estuary south of the town of [[Chepstow]].

The [[Mounton|Mounton Brook]] and [[Nedern Brook Wetlands|Nedern]] Brooks enter on the Monmouthshire side between the two motorway crossings. The [[Port of Bristol]] is on the [[Severn Estuary]], where another River Avon flows into it through the [[Avon Gorge]]. The [[River Usk]] and the [[Ebbw River]] flow into the Severn Estuary at [[Uskmouth]] just south of [[Newport, Wales|Newport]].
