Eruvin 24: Seeing the Water for the Trees

"New faces": More on the courtyard garden area - set up to be part of one's residence, where people may we'll need to carry. What if you take one amah at a time and fence it off? What if you broach the fence and seal it off, to the size of a pomegranate - will that be sufficiently redone, such that it's fundamentally a new item (as per the impure and its repair vs. reconfiguration to a new sandal, a case from Masekhet Shabbat, if you recall). Also: What happens if a residential courtyard has been flooded - does that water function like planted trees or does it make it uninhabitable, and then not a place where it would be permitted to carry? Abaye and Rava have different solutions to re-establish the area as a place to carry.
