anybody know how the tunnel flooding worked out?
They only flooded a few tunnels, and it is limited by the type of geology the tunnel is in - limestone tends to dissolve in sea water, making the ground above unstable. Preferred method is to use explosives found in a tunnel to destroy it.
They found that searching a tunnel complex sometimes yields lots of gold and cash, documents, plus server farms. The ones they cannot get to, tend to find bunker buster bombs.
It is better to send dogs and robots into the tunnels.
The IDF was even surprised by the vast extent of the tunnels in Gaza.
The only thing keeping them from blowing the tunnels in Khan Unis and Rafah up is the remaining hostages.
They are being used as human shields by Sinwar the last Hamas commander not neutralized.
Go to YouTube and search for TBN Israel. They have been posting videos daily of updates from Israel and Gaza.
Another source calls themselves Raptor News. Also on YouTube. Much better info than anything else I have seen.
