Page 1 > of 2 Q - ZOOM + 4. Consider the two separate sets of measured data for a silt-loam soil measured by Mualem (1976): (1) suction versus water content, and (2) suction versus relative permeability of unsaturated soil, k/ks. Assume that 0s 0.396, 0res = 0.131, and Ks=5.74×10-7 m/s. a. Using the method of least squares in Excel, compute the best-fit values for αNG (kPa¹) and nvg for the van Genuchten (1980) relationship for data set # 1 (assume m = 1-1/nvG). See the example spreadsheet in the homework folder under the files section of Canvas for help in performing this calculation. b. Repeat part (a) and estimate the λ and ac parameters for the Brooks and Corey (1964) SWRC for data set #1. Note that you may need to include an "if" statement at the air entry suction. c. Plot the data for the SWRC versus the fitted van Genuchten (1980) and Brooks and Corey (1964) curves. Which relationship matches the capillary pressure data better (BC or VG)?
