Unloved city rivers around the world – your pictures and stories

You shared your experiences, photos and memories of forgotten or unloved rivers in cities around the world, from Birmingham to Belo Horizonte

LA's river is not your average city river, and is iconic for very different reasons to the picturesque Seine of Paris, or historic Thames of London. It is a mostly dry abandoned concrete channel, used for car chase movie scenes and home to a growing homeless population - though, as Olly Wainwright reports, there are ambitious plans to "revitalise" it.

Although rivers often become celebrated focal points of cities around the world, many others are buried, neglected, underused or mistreated. We asked you to share your photographs and memories of unloved city rivers around the world. Here's a selection of some of the best contributions, from tales of the River Irwell in 1940s Salford - so polluted with bleach it could give those who fell in "peroxide hair" - to exploring forgotten and historic rivers in water crisis-stricken Sio Paulo.
