Flat V weirs are used to calculate the flow of a river or stream. Predominantly, Flat V weirs are used where the flow rates are low and river sections quite narrow.
Note: When the downstream level of water in the river should be taken into account for backwater correction, use the flatVWeirBackwater transformation instead of the flatVWeir transformation.
Input
- headLevel: is the upstream level of water in the river measured from the top of the crest at the bottom of the V.
- type: type can be 'simple' or 'crest_tapping'. With 'crest_tapping' the pressure tapping measurements are taken and used for the flow calculation.
