If B/D is known then, we can calculate by B=Dx.

Put value in every equation. If only D is known you will only get V. Not Area and Perimeter.

I think depth must be known. Right?

Explain the answer clearly.

In its design problem, we were assumed "D" value just and then followed the relations.

So, the right option is Depth only.

Yes, it's Only depth.

Only depth should be known;

Critical velocity V = 0.55mD^0.64.
