Model Form #1

log₁₀(SS) = 0.185 + 0.715 log₁₀(TURB) + 0.188 log₁₀(Q)

where:

SS is computed suspended sediment, in milligrams per liter
TURB is turbidity, YSI model 6026, in formazin nephelometric units
Q is computed discharge, stage-discharge rating curve, in cubic feet per second

Notes

This model is used to compute values at this station only from 1999 through 2006, the range of time when a 6026-model turbidity sensor was used. Beginning in 2007, a 6136-model turibidty sensor was installed, resulting in a change to the model.
