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