This shouldn't be an issue. If you have water touching your tent, you're probably doing it wrong.
Note: the tent has a rain fly, which is a fly, not the tent. The fly should cover the top and sides of the tent, with perhaps some exposed doorway bit.

Before you pitch the tent, picking the location is important.
You want a subtle / gentle slope, not underneath any trees which may attract lightning or shed limbs in windy conditions.

First, clear the tent area of any pebbles sticks, etc.
Next, you want to lay down a waterproof tarp. Fold any overlapping bits of tarp, which are wider than the tent base, to fit. You don't want the tarp outside the tent base, but as close to the edge as is reasonable.
Lay the unrolled tent on the tarp, with the door on the downhill edge. Fix / refold tarp if necessary, and stake the tent.
Next, you want to take a stick or the claw end of a hammer, etc. and dig a 1/4" to 1/2" deep channel in the dirt around the back and down the sides of your tarp. It doesn't need to be wide, just a line in the dirt that will redirect any rivulets around your tent. It's primarily meant to redirect rivulets which fall off the tent's fly, so it needs to be beneath that overhang. This is not a time consuming project, just drag the tool around and visually verify that your channel isn't bad. Quick and easy. Don't over-think it. You should be able to shuffle your feet over the channel to quickly remove it when you break camp. (LEAVE NO EVIDENCE!!!)

Finish pitching the tent.
