Howdy
in the chage set you crossed a lot tram lines without indicating how the line can be crossed. Maybe revisit all those and check please.
Also, the footways that cross water need information on how they cross the wayter. Presumably by bridge. See this article for more information:
https://wiki.openstreetmap.org/wiki/Key:bridge

Two more things: The metadata of this CS suggests you used bing. As far as I know there's much better imagery for the region. Please check that in your editor in the right hand panel.

Also you didn't give a source for your information. Please do so in the future. Thank you

cheers
