This one is made from plastic sheeting forced by the weight of water against sloping metal supports. These sloping supports are held in place by vertical scaffold poles driven in to the canal bed. It's hard to tell from the photo, but it doesn't look like much water has yet been pumped out from this side of the dam.

Incidentally, I don't like Blogger's new way of displaying photos once you've clicked on them. They seem to be smaller than before, and it doesn't help to have the dim remains of the blog around the outside. Also the scroll bar disappears from the original blog once you've closed the photo view.

Thanks Halfie. I suppose it's a sort of 'temporary' dam, but maybe you've explained that already and I still need to go to that post. I'll keep looking back...
Okay, I've been to your original post and seen your answer there. Thanks Halfie, but could you tell me what the coffer dams are there for? I suppose I could look it up on google, but it's more fun to ask you :)
Yes, they're temporary dams to allow work to be undertaken which would normally be under water.
Thanks Halfie!
