Niagara falls recedes at a rate of approximately 3 to 5 feet (0.9 to 1.5 meters) per year due to erosion caused by the falling water. This erosion primarily affects the soft rock beneath the falls, leading to the gradual retreat of the waterfall. Over thousands of years, this process has significantly shaped the landscape of the area. Efforts have been made to manage the flow of water to reduce erosion and preserve the falls.
The falls have eroded seven miles since their creation!!!
if you refer to the speed of the water as it falls, it is at 9.8m/s

I very much doubt anyone knows. You could estimate, but no one could be able to say an exact amount because you would have to monitor every inch of ground in the whole world...and I doubt anyone could be bothered to do that. XD Sorry, that wasn't very helpful. :/
