The above monochrome image shows water flowing over a two-bump weir in a flume. The flume is located in the ITLL Lab at University of Colorado-Boulder College of Engineering. This photo was taken in collaboration with Will Dietz, Kelsie Kerr, and Maridith Stading.

This is awesome, it almost looks like something made in a 3D modeling software. I also like how you can see the flow transition from laminar to turbulent.
The choice to put this image in black in which is creative and resourceful in regards to the coloration and lighting issues that you said you faced with this image. My only suggestion would be to maybe try to change the contrast or brightness or something to make the reflections in the bottom left less prominent.
I love the decision to make it black and whit, it makes it look very beautiful.
open channel flow, two hydraulic jumps, acceleration over obstacles, depth of upstream vs downstream
The turbulence on the tail end of the flow looks really good in black and white. I like the bright spots showing the rough surface of the water
I like that you decided to do black and white! I think this is the perfect chance to do so as it highlights the flow.
To answer your question, I think you could have shown a little more on the right to see how the flow starts, but it is also not needed.
I really like how your image shows the flow following the contour of the obstacle, and how you capture it becoming turbulent after the obstacle.
I really like that you chose to use black and white! It brings out the shadows and highlights in really interesting ways and makes the flow look really cool.
