River meanders follow a sine-generated curve: = sin(2s/S)
: deviation angle: max()s: distance along the pathS: total path distance in a wavelength

With 2 measurements per vertical the accuracy of flowrate calculations is within 3%, with 1, it becomes 4.3%.
Gauging stations: site must be chosen carefully, the resulting rating curve (h-Q) must be stable in time and be sensitive enough
Typical rating curve:
Q = c(h - a)n n > 1Stage (h)Flowrate (Q)Q = 0a
