Abacus of the Gec-Alsthom gates

Appendix
- Available translations on this page : français -

We recalculated the abacus from the equation we use. We observe they are similar to those given by the Gec-Alsthom company:

  • For AMIL gates with Zmax=0 (Maximum water level set on axis elevation) :

  • For AVIO gates (HC in red, BC in blue) :
  • For AVIS gates (HC in red, BC in blue) :

From these equations we also obtain the following points:

  • For AMIL gates with Zmax=0 :
