Weren’t the Marsh wetlands in Iraq drained by Saddam Husein ?
93 ish uprising. Saddam drained the delta, moved the surviving Arabs into Basrah.
The confluence of the Euphrates and Tigris is called Shat Al Arab, flows through SE Iraq and borders Kuwait and Iran. KSA has no border with the delta, Kuwait is in the way.
Spent a awhile thereabout in 2003. Brit sector during OIF. Nice people, except for the ones wanting to kill us.

Hussein had part of them drained to get rid of the Marsh Arabs--to punish them for their role in the 1991 uprising against Saddam Hussein's government.
Apparently things were more complicated than one might think.
