There is nothing in RET (and I challenge you to find a source that argues your side) that says the surface of a flowing body of water must be shaped by the curvature of the earth.
So the River Nile juts out into space? It doesn't follow the curvature of the earth?
I'm done. I gave you the reasons. You being too obtuse to acknowledge them isn't really my problem. I have answered the issue and have not had one counter example of why my assertion is not true.
So you can't answer the simple challenge: Find a source that argues your side that says the surface of a flowing body of water must be shaped by the curvature of the earth. This is an inherent part of your outlandish argument. You have claimed it without any support. You have ignored that it's not true at given locations, such as the Falls. You fail.
I did. the River Nile is my example. It flows, it should follow the curvature of the earth or jut out into space. I'm at the point where I feel our respective IQs are too far apart for either of us to enjoy a debate so I'm going to let the other FErs entertain you from now on.

It has been pointed out, many times, that the Nile is virtually flat wrt a datum that follows the curvature of the Earth.
At least you get the basic premise. Please explain to Gulliver if you have more patience than me.
I did a whole thread on the Nile and the gradient proves the Nile cannot be curving with earth, because a gradient itself is a flat earth concept (triangles). When you apply RET to it, the gradient is less than the curvature of earth and it appears the Nile would flow towards its own middle from both ends. Its a cool thought experiment if nothing else. Play with the numbers. The least you will learn is all gradients are based on a flat earth, and that itself is interesting.
I tend to disagree and I am not sure why you would contend that a gradient can only exist on a flat surface. If the slope changes with respect to the datum, whether the datum is flat or curved, you can calculate a gradient. The second definition below appears to be the relevant one:
