Table 4
Regression equation form and statistics for gaging stations in the Middle Yuba and South Yuba Rivers in the upper Yuba River watershed, California.
[Note: Regression variables, which include suspended-sediment concentration and streamflow, were converted to base-10 logarithms. r2, coefficient of determination. a is the Y intercept and b is the regression coefficient in equation 1. N, number of data points: Data points were used to determine group-averaged dataset; group-averaged data points were used in the regression analysis]
