As a suggustion, can you not make a fat channel and block out the parts you dont want?

You could use lots of blocks to make stairs

Perhaps I misunderstand you?

1/ You can make a solid volume STL file and import this onto a cartesian grid using the PARSOL cut-cell method to cut this object shape from the background grid.

or 2/ Use a Body fitted grid

or

3/ Represent the depth varying through blocking out a cartesian domain with object shapes from the library of such objects, wedges, rectangles, arcs, whatever.

If you are using the hydraulic analogy, you can use porosity fields, with a porosity field, you can simulate flows with different depths, at least it worked for me.

With porosity fields ive simulated bumps or obstacles for inducing an hydraulic jump.
