Editing River Hull (section)

==Course==
The [[source (river)|source]] of the River Hull is in the [[Yorkshire Wolds]]. It rises from a series of springs to the west of Driffield, near the site of the medieval village of [[Elmswell, East Riding of Yorkshire|Elmswell]]. The Elmswell Beck flows eastwards from these, and is joined by the Little Driffield Beck, which flows southwards from Little Driffield. It continues as the Driffield Beck, flowing around the south-western edge of [[Driffield]], where it is joined by the Driffield Trout Stream. After the junction, it becomes the River Hull or the West Beck and flows to the east, before turning south to reach Corps Landing. For much of the route below Driffield, the [[Driffield Navigation]] runs parallel to the river.<ref>Ordnance Survey, 1:25,000 Explorer map, Sheets 294, 295</ref>

The river from Corps Landing to its mouth is navigable. At [[Emmotland]], it is joined by the Frodingham Beck, which is also navigable, and leads to the canal into Driffield, which forms the major part of the Driffield Navigation. Scurf Dyke joins from the west and is followed by Struncheon Hill lock, which marks the end of the Navigation, and the official start of the navigable River Hull. Below here, the river is tidal. The tidal range of tides can be up to {{convert|7|ft|m}} in winter and {{convert|4|ft|m}} in summer.<ref name=jane>{{harvnb |Cumberlidge |2009 |pp=114–115}}</ref> Just above the lock, the Beverley and Barmston Drain, which collects water from the catchwater drains on either side of the main channel, flows under the navigation in a tunnel, and runs just to the west of the river almost to its mouth.<ref>{{harvnb |Hadfield |1972 |p=85}}</ref> Below the lock, the surrounding land is almost at sea level, and the river is constrained by flood banks on both sides.<ref name=os293>Ordnance Survey, 1:25,000 Explorer map, Sheet 293</ref>

On its route southwards, the river passes the former junction with [[Aike Beck]], once navigable to Lockington Landing, but the stream was subsequently re-routed to join the [[Arram Beck]]. The [[Leven Canal]] used to join on the east bank, but the entrance lock has been replaced by a sluice. The Arram Beck flows in from the west, and then the river is crossed by Hull Bridge, the cause of repeated disagreement between the owners of the Driffield Navigation and the [[Beverley|Corporation of Beverley]], who owned the bridge.<ref name=hadfield86>{{harvnb |Hadfield |1972 |pp=86–89}}</ref> Just above [[Beverley Beck]], which joins from the west, is Grovehill Bridge, now a lift bridge but once a ferry bridge.<ref name=crosby31>{{harvnb |Crosby |1980 |p=31}}</ref>

Once the river reaches the outskirts of Hull, its course is marked by a series of bridges, most of which open to allow boats to pass. There are swing bridges, lift bridges and bascule bridges, and the river becomes part of the Port of Hull.<ref>{{harvnb |Cumberlidge |2009 |p=153}}</ref> The river, which is the dividing line between West and East Hull, bisects the city's industrial area. The bridges can cause traffic delays during high tides,<!--why? because they have to be raised? --> though river traffic is less than it once was. The Beverley and Barmston Drain rejoins the river above Scott Street Bridge.<ref name=os293/> Below North Bridge, an unused dry dock on the west bank marks the former entrance to Queens Dock. Below Drypool Bridge, a muddy basin on the east bank was once the entrance to Drypool Basin and Victoria Dock.<ref>Ordnance Survey, 1:10,560 map, 1938/46 edition</ref> The river reaches its [[confluence]] with the [[Humber]] [[Estuary]] in the centre of [[Kingston upon Hull]].<ref name=os293/> At its mouth, a tidal barrier has been constructed to prevent tidal surges from entering the river. In the past, these had regularly flooded the town and the flat countryside to the north.<ref>{{cite web |url=https://www.transport-network.co.uk/Hull-barrier-turns-tide-on-threat/2110 |archive-url=https://web.archive.org/web/20201206122537/https://www.transport-network.co.uk/Hull-barrier-turns-tide-on-threat/2110 |archive-date=6 December 2020 |url-status=live |title=Hull barrier turns tide on threat |publisher=Transport Network |date=30 January 2008}}</ref>
