Dettifoss and me admiring the view.
Dettifoss is a waterfall in Iceland that is known as the most powerful waterfall in Europe. It means that its average discharge (193 cubic meters per second) numbers are above all others. Dettifoss surely is a magnificent sight but I strongly recommend to go and see Selfoss also. It is a couple of kilometers farther away (upstream) from the car park but it is worth to take a look. I liked it more than Dettifoss for several reasons but more about that in the future.
As an engineer I would like to clarify : The waterfalls with the largest DISCHARGE are the Rhine Falls in Germany with an average during summer of 700cubic meters per second and in winter with an average of 250. As the height of the Rhine Falls is only 23m and the height of the Dettifoss is around 100m, Dettifoss has more potential energy and could produce more power than the Rhine Falls.
