Weirs
• types:
– broad crested weir:
• calculated Q/h (x-section, dx)
• critical flow
– special weir:
• specified Q/h
• valve regulation
• head loss factors (energy loss)
• geometry
– level-width (increasing)
– x-section DB

–
–
–
overflow: variable crested weir
underflow: vertical sluice gate
discharge: pump
radial gate: no head loss
• attributes:
– gate width
– sill level (upstream)
– max. speed
(gate level change per time)
• head loss factors (energy loss)
