I am not sure if you mean flooded as in too much gas or submerged into water. If it is by gas then you could just let it set and try again later or take out individual plugs and use compressed air to blow them dry.
Now if you are talking about water that is a whole different beast. You need to remove all the plugs at once and turn the engine over several times to blow out any water. Dry the air filter out. Then you need to put fresh oil in it.
the engine is flooded with gas

It depends on how badly the engine is flooded. If you've solved the original problem you can always pull the plugs, purchase an air gun with a long extension tube, connect it to a compressor and blow each cylinder completely dry. Make sure you mark the sparkplug wires first, so you'll be able to get them back where they were. Or... if it's just moderately flooded you can use some starting fluid to force the engine to start. Ether in the starting fluid is a lot more volatile and will burn when gasoline won't. If it were me, I'd try the starting fluid first and if that doesn't work THEN I'd escalate to compressed air in the cylinders.
Possible internal engine damage.
An ATV's engine can get flooded if you hold the throttle open for too long. At the bottom of the carburetor, there is a screw that can be opened to drain it.
Remove spark plug and dry it. Should start.
people in very dry areas got flooded and people in very wet areas went dry.
Chances are no it will need to be rewired. Because of all the salt that's in the water you will need to have the whole car rewired.
you can try getting the engine blowed out, but that may not solve it if it has sat a long period of time.
you flooded it
A wadi is just a dry river bed,flooded in the rainy season. There are thousands of them.
