The basis for this approach is based in a rights based approach to health recognising the right of people to be involved in decisions that affect their health and the river as blue / green infrastructure is one such wider determinant of health. At a national level in Wales this is closely aligned to the ways of working and wellbeing goals defined in the Wellbeing of Future Generations (Wales) Act (Welsh Government, 2015). © URBAN HABITATS Rev WEB 01-11-19 ISSUED 01 NOVEMBER 2019 Scope | Route of the River Rhymney from its Source (Not to scale) Study location © URBAN HABITATS Rev WEB 01-11-19 ISSUED 01 NOVEMBER 2019 Scope | Study Area (Not to scale) Wider Context Area From Rumney Playing Fields the character of the river environs changes and is more accessible (at least on the east bank).

Figure X highlights some The River Rhymney is one of four river valleys key site records. in Cardiff: the Taff, Ely, Nant Fawr. These rivers are integral to the 2000 hectares of At the North End of the study area there is a amenity space and 400 hectares of open Site of Special Scientific Interest (SSSI) for its recreation space in the City as this ‘green’ and geological importance, the Rhymney River ‘blue’ space or infrastructure are often found Section SSSI.

Several smaller tributaries feed into the character.

This in itself is notable as the river flows into the Severn Estuary – which with a tidal range (from high to low tide) of about 15 metres – the second largest tidal range in the world second only to the Bay of Fundy in Canada. It is noted however that these natural settings
