Currently displayed models were developed using data from YSI 6-series sonde. Equipment was upgraded to YSI EXO sonde on 8/24/20. This will introduce additional uncertainty that may not be reflected in the computed confidence limits.
Model Form #1
SSR =
- 8.662 + 14.362 sqrt(TURB)
where:
- SSR is computed suspended sediment, in milligrams per liter
- TURB is turbidity, YSI model 6136, in formazin nephelometric units
