assuming you meant feet because 5 meters is about 16 feet. Heck 5 feet into rough ground can slip to a bad injury or death and that's nto even considering these are young girls slightly over a meter tall.
Sure, it looks fine until you realize there were rocks all around. One slip-up on the landing and hitting your head onto a rock can cause irreparable damage or even mortality. Especially the rocks could be extremely slippery since there could be moss growing on them.
People have died from less, and some have survived far more. It's not probable, but quite possible. Depends entirely on how one lands, and a river full of slippery rocks... yeah no, I'd rather avoid it.
