            Book—

 

Page 4: 1st column. Below equation 6. “where z1 and z2 are points below and above the wetting front” was replaced with “where z1 and z2 are points above and below the wetting front”

“Combining equations 7 and 8.”

 

Page 4: New equation 9.

Page 4:  2nd column. Below equation 9. “q2 is the volumetric water content of a wetting front; q1 is the volumetric water content below a wetting front” was replaced with:

q1 is the volumetric water content above a wetting front; q2 is the volumetric water content below a wetting front.

 

Page 5.  1st column. Figure 2. Top of graph changed from “q2 and q1” to “qt2 and qt1”

Page 18. 3rd paragraph.  4th sentence, “Finally, neither the Parameter-Estimation nor the Ground-Water Transport Processes work when unsaturated flow is specified beneath streams” was replaced with "Parameters can be used to define streambed hydraulic conductivity only when data input follows the SFR1 input structure (Prudic and others, 2004). The calculation of sensitivities for, or estimation of, parameters using the Sensitivity Process are not supported by SFR1 nor SFR2. Additionally, the Ground-Water Transport Process is only available using the original SFR1 input structure and is not available when simulating unsaturated flow beneath streams."
