Ordinary concrete weir¶

The geometry of the weir made of ordinary concrete is defined with reference to the following figure:

SchemaGeometricoCLS

Geometrical diagram of the concrete weir

With reference to the figure, the data the user must enter are the following:

HB [m]:

Weir body height

POSB [m]:

Distance between the face upstream the weir and the farthest edge upstream the foundation

LC [m]:

Crowining width

HC [m]:

Crowning height

SPV [ °]:

Inclination of the downstream face with respect to the vertical (Angle measured as positive anticlockwise)

HFV [m]:

Downstream foundation height

LTF [m]:

Total foundation length

LT [m]:

Foundation cut-off wall width

ST [m]:

Inclination of the downstream cut-off wall wit respect to the vertical (Angle measured ass positive clockwise)

HFM [m]:

Upstream foundation height

BB [m]:

Base of the weir body

Besides, the concrete weir is completely defined when its specific gravity is defined in the general information.
