1. 1. Bernoulli P3 and P1m bed level is reference line
2. At P3 supercritical (schietend) or subcritical (stromend)?
3. At weir free flow (volkomen) or submerged flow (onvolkomen)?
4. At which depth switch between free en submerged flow?
5. Discharge coefficient broad crested weir?
6. Suppose water level at P3 is 0,52 m, discharge coefficient weir?
