It will depend which drain is blocked. There are several.

Get a torch out and have a peer down into the scuttle. On the passenger side between the cover of the ECU box and the central air intake there's a gap with various pipes and the auxiliary water pump that you can see past. Or on the drivers side unclip the cover on the wiper motor area and look down under the air intake. If water is pooling there it's a right pain to resolve and overflows into the cabin. This CAN be the source of huge amounts of water.

The commonest problem is the aircon drains inside the cabin, which "seem" to overflow more on the passenger side, though they're symmetrical in theory.
The passenger side one is easier to clear as there's less to remove so start there.

But first take the front mats and carpet out (both sides) and start mopping up, then remove the "plank" and dry that out too - it may or may not be screwed down depending if it has been taken out before. The carpets soak up massive amounts of water as you'll soon discover.
Old towels come in handy.
