I'm trying to run through various scenarios in my head to see if I'm safe and can handle different emergency situations.

One I realized might be trouble is if I were in a harsh rain storm, and a branch fell and pierced my tarp.

How would I repair it?

My duct tape wouldn't seal with the water present. The water might also be enough to get my bag wet.

I if it were small enough I guess I could take my rain jacket and tape it to the inside of the tarp but what if the tarp wear ripping or the whole was too large.

Anyone thought about this scenario?
