Hi
I am modelling a basic radial gate and looking for explanation of the gate descriptors
– trunnion exponent
– opening exponent
– head exponent
I’m guessing that some of these may relate to gate radius but just cant find anything on the net. HECRAS has a set of defaults but do they necessarily apply to my gate. Not sure.
Also the data entry only allows one submerged orifice coefficient but the USACE design chart for submerged tainter gates would suggest that this coefficient can vary quite a bit depending on the gate opening to d/s depth ratio. Does anyone have any guidance on this?
Thanks
