Hydraulic test¶
In the hydraulic test, different quantities are calculated according to the type of stilling device adopted. Depending on the different cases, the expected results of the hydraulic calculation are the following:
# Basin not coated with auxiliary dam¶
z0 [m]
Rise in the upstream water level
zg [m]
Water level on the notch (NB: the water on the notch flows under critical state conditions)
zv [m]
Reattachment level of the fluid vein on the face downstream
z1 [m]
Water level downstream the weir
fb [m]
Soil profile level at the distance of maximum excavation (maximum excavation depth)
z2 [m]
Rise in the water level immediately upstream the auxiliary dam
zum [m]
Current level downstream the weir under uniform motion conditions
lbmin [m]
Basin minimum length
hcbmin [m]
Minimum height of the auxiliary dam
# Embankment basin, coated with aux. dam¶
z0 [m]
Rise in the upstream water level
zg [m]
Water level on the notch (NB: the water on the notch flows under critical state conditions)
zv [m]
Reattachment level of the fluid vein on the downstream face
z1 [m]
Water level downstream the weir
z2 [m]
Rise in the water level immediately upstream the auxiliary dam
zum [m]
Current level downstream the weir under uniform motion conditions
lbmin [m]
Basin minimum length
hcbmin [m]
Minimum height of the auxiliary dam
# Depression basin, coated with auxiliary dam¶
z0 [m]
Rise in the upstream water level
zg [m]
Water level on the notch (NB: the water on the notch flows under critical state conditions)
zv [m]
Reattachment level of the fluid vein on the downstream face
z1 [m]
Water level downstream the weir
z2 [m]
Rise in the water level immediately upstream the auxiliary dam
Zum [m]
Current level downstream the weir under uniform motion conditions
lbmin [m]
Basin minimum length
hcbmin [m]
Minimum height of the auxiliary dam
# Absence of basin and auxiliary dam¶
z0 [m]
Rise in the upstream water level
zg [m]
Water level on the notch (NB: the water on the notch flows under critical state conditions)
zv [m]
Reattachment level of the fluid vein on the downstream face
zum [m]
Current level downstream the weir under uniform motion conditions.
