So now I am facing my next step on the ladder of learning.
How do you calculate the width of the spillway I am going to put on my waterfall box.
I am going to be building a triangle shaped box in the corner of my pond. It will be 24in x 24in x 34in, and will be about 18in to where the spillway will be. i have calculated the volume of the box to be approx 57.7gallons (not sure of the math) my pump is a 3600gph. I have found some formulas, but they ask about the thickness of water?!?!? I don't really know how to put all the figures together and come up with a spillway width. Any help or pointers to formulas?
