River Itchen, Hampshire#Etymology

The name is likely from a Brittonic language and in meaning unknown. The settlement of Itchen Abbas, before its abbot's ownership, is transcribed by early Middle English orthography which used the letter c followed by e or i to denote the {{IPAc-en|tʃ}} sound and an e invariably after an n to avoid those down strokes being ambiguous thus, as Icene in the Domesday Book of 1086.Mills, David (2011), [https://books.google.com/books?id=tXucAQAAQBAJ&dq=%22Itchen%22+meaning+of+name&pg=PA259 A Dictionary of British Place-Names], Oxford University Press, {{ISBN|978-0-19-960908-6}} (p. 259) The name, in upper parts was once seen as interchangeable with the tributary Alre.{{cite book|last=Knight|first=Charles|title=Geography: The English Cyclopaedia, Volume IV|year=1867|publisher=Bradbury, Evans|location=London|pages=631|url=https://books.google.com/books?id=UAVCAAAAYAAJ&q=Alre}}{{cite book|last=Camden|first=William|title=Britannia|publisher=J.

The river then carves its way west passing the villages of Avington, Itchen Stoke, Itchen Abbas, Martyr Worthy, Easton, and Abbots Worthy; to enter the cathedral city of Winchester it crosses Winnall Moors to turn south for its remainder.Ordnance Survey (2004).

It flows in anabranches through the city, some close enough to Winchester Cathedral to cause problems to the foundations in the past. The main channel flows through Winchester City Mill and to the east of the city's Roman walls, along a promenaded reach known as "The Weirs".

Its waters can overflow into water-meadows, passing: the Hospital of St Cross; the villages of Twyford; Shawford; between the town of Eastleigh and the village of Bishopstoke; and through Itchen Valley Country Park before reaching the northern suburbs of Southampton at Mansbridge. Between Winchester and Mansbridge, sections were deepened or widened for the long-disused Itchen Navigation, and the former towpath forms part of the Itchen Way.Ordnance Survey (2004).

Monks Brook flows into the Itchen at Swaythling, and the river then passes under Woodmill Bridge and becomes tidal. Four further bridges cross it before the Test estuary in Southampton Water:

• Cobden Bridge, a road bridge connecting Bitterne Park and St Denys.
• Cobden railway bridge carrying the Southampton – Portsmouth railway line. Opened in 1866, the bridge is supported by two sets of cast iron cylinders resulting in three 115-foot openings. The bridge's girders are made from wrought iron.{{cite book |last=Moody |first=Bert |date=1992 |title=Southampton's Railways |publisher=Waterfront Publications |page=93 |isbn=0946184631}} In order to try to prevent the Northam Bridge Company from trying to block the bill authorising the railway, it was agreed that pedestrians would not be allowed to use the bridge.{{cite book |last=Marsh |first=Keith |author-link= |date=2007 |title=The Book of Bittern From Roman Town to City Suburb |publisher=Halsgrove |page=145 |isbn=9781841146355}} Even so the opening of the viaduct diverted traffic from other crossings with the Woolston Floating Bridge seeing a significant fall in income.{{cite book |last=Jones |first=B.C |date=1977 |title=Crossing the Itchen |publisher=City of Southampton |pages=14–15}}
• Northam Bridge, a road bridge carrying the A3024 road from Bitterne Manor to Northam, which was originally opened in 1799.{{cite book | last = Holt | first = John |author2=Anne Cole | title = A bend in the River | publisher = Bitterne Local History Society | date = February 1992 | location = Southampton }}
• The Itchen Bridge, a high-level toll road bridge connecting the docks area with Woolston. This replaced the Woolston Floating Bridge (a chain ferry) which had previously crossed the river at this point.

Between the latter two, the river passes St Mary's Stadium, the home of Southampton F.C. As the river meets Southampton Water it passes several rowing clubs, sailing clubs and the major mixed-development on the left bank in Woolston, called Centenary Quay.

The lower part of the river is an important yachting centre and contains several marinas, sailing centres and boatyards. From seaward they are:Admiralty Charts: Small Craft Folio SC5600 Chart 10A

• Ocean Village Marina (MDL), on the western shore just below the Itchen Bridge and close to the city centre
• Southampton Water Activities Centre, almost underneath the bridge on the western shore
• Itchen Marine, just above the bridge, principally a towage business but with some berths for yachts and the only fuel berth in the river
• Merlin Boatyard, opposite Itchen Marine, on the eastern shore
• Lauren Marine Services, a small marina on the eastern side
• Ocean Quay and Solent Breeze Yacht Charter on the west side
• Shamrock Quay (MDL), the biggest marina in the river, also on the west
• Saxon Wharf (MDL) is almost adjacent to Shamrock Quay, containing the biggest boat lift in Britain (200t){{cn|date=October 2023}}
• Kemps Quay Marina on the eastern (now northern) shore, a drying marina and boatyard
• Quayside Marina, a single long pontoon next to Kemps
• Drivers Wharf, another single long pontoon, parallel to the shore, with a crane and boatyard

Above Northam Bridge, the limit of navigation for masted craft, are the Vespasian Road boatyard and numerous small establishments.

The Environment Agency measure water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish, and chemical status, which compares the concentrations of various chemicals against known safe concentrations. Chemical status is rated good or fail.{{cite web |url=http://environment.data.gov.uk/catchment-planning/glossary |website=Catchment Data Explorer |title=Glossary (see Biological quality element; Chemical status; and Ecological status) |publisher=Environment Agency |date=17 February 2016}} 30px Text was copied from this source, which is available under an [http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ Open Government Licence v3.0]. © Crown copyright.
