The upper side in rectangle flow is open to the air. Across the rectangle cross section we have to put the batten with the same lenght as cross section (B). All we have to do is to measure the water flow above the batten (h) and to use this equation. g=9,81m/s^2 Easyer method for me:

Q=B(gh^3)^1/2
