Table 3. Regression models selected to show the relation of streamflow and turbidity to suspended-sediment concentration, Johnson Creek basin, Oregon, water years 2007–10.


[Station reference: Complete station names are shown in table 1 and locations are shown in figure 1. Regression model equation: Log, log base 10; Q, streamflow, in cubic feet per second; SSC, suspended-sediment concentration; T, turbidity, in Formazin Nephelometric Units (FNU). Adj R², adjusted coefficient of determination. MSPE, model standard percent error]
