x = distance (m)

y = settlement (mm)

  

S = 1000 * Smax * e^(-y^2 / (2 * i^2))

If VL specified:

Smax = -(0.00313 * VL * d^2) / i

Else:

Smax = max(settlement readings)

S = settlement

d = diameter (m)

i = width of settlement trough (mm)

k = coefficient

e = exponential constant

y = distance (m)

VL = s / (π/4 * d^2)

s = 2.5 * 0.3 * i * (Smax / 1000)
