I’ve always thought that the size of a waterfalls “grandeur”, to coin a phrase, was a product of both height and volume per second and/or width. But all waterfall lists I’ve found online only list one or the other.
If I wanted to compile the largest in both of these categories (height * volume and height * width), I could simply look at lists of the highest and widest and then find out the other datum indepently through a web search. But I could theoretically be missing waterfalls that were not in the top 10 in either category but when multiplied are still impressive.
Heck, I thought I was on to something when I stumbled upon worldwaterfalldatabase.com . It even had a downloadable KML file but upon inspection it also only has one or the other, not both
