  • River stats The River Aire has a catchment area of approximately 2,060 km², which is mainly rural in nature. It also contains the major urban areas of Bradford and Leeds, as well as smaller towns such as Skipton, Keighley, Bingley and Castleford. The Aire joins with the River Ouse close to the upstream end of the Humber Estuary at Goole. This is approximately 100 km from its source in the Pennines and the river is relatively wide and deep over at these lower reaches. The River Calder (the main tributary of the River Aire) rises on the Pennine Moors west of Todmorden. It is predominately an urban river flowing through the West Yorkshire conurbation towns of Halifax, Brighouse, Huddersfield, Dewsbury and Wakefield, before joining the River Aire at Castleford some 87km from its source. The River Don in South Yorkshire starts its life high on Dunford Moor in the Pennines, 485m above sea level, west of the market town of Penistone. It flows in a generally eastern direction, migrating through the major cities of Sheffield, Rotherham and Doncaster, before finally joining the tidal River Ouse at Goole, some 111km from its source. Its major tributaries include the 41km River Rother, which starts at Claycross in Derbyshire and joins the Don in Rotherham, and the 47km River Dearne, which starts near the town Denby Dale and joins the Don in Mexborough.

  • 18. Factors for success Clear Terms of References and objectives ~ why are we working together / what do we want to achieve / what are the roles of different partners? Time and commitment ~ continuity of staff is important Political buy-in and support from senior staff in partner organisations Understanding roles / responsibilities / drivers & priorities / limitations of partners Interdependence ~ recognition that one partners can’t solve the problem in isolation Strong leadership Trust, open dialogue and accountability
