Erosion is largely done by sediment being transported by the water I believe. The same principle is used in cutting water jets, it isnt the water pressure that cuts things, the water is a medium for abrasive materials
I think water by itself can randomly break a few loosely bound atoms off the surface of anything. But the rate of that dissolution is dwarfed by the wear effects of the sediment being transported by the water, which is the primary material remover.
