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

Culverts

• attributes:– upstream & downstream invert– length– bed resistance– valve regulation

• head loss factors (energy loss)• geometry:

– shape– level-width– x-section DB

Regulating (Pump)

• specified discharge • types:

– function of time (boundary editor)

– function of hydraulic conditions:

• water level

• reservoir inflow

Control Structure

• regulated flow moveable gate• type:

– 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)
