Hallo:

I am using Telemac-2D Version 6.2. In the user's Guide, the flow of a weir is calculated by

Q = mu * sqrt(2g) * (upstreamlevel - threshold level) ^ 1.5

My qustion is: where the weir width has been taken into account? It is not included in the equation.

Best wish

Kutti

Hello,

You can perhaps find formulas in hydraulic books that use the weir width, but probably to compute the coefficient mu, which is here just given by the user.

With best regards,
