The RETC program was run under the van Genuchten capillarity model generate van Genuchten "N" and <br /> van Genuchten "a" capillarity fitting parameters. The Burdine or Mualem soil moisture retention model <br /> was chosen based on lithology, but also confirmed with relative permeability laboratory data for a <br /> representative fill unit soil sample and a representative clay unit soil sample, respectively. <br /> Table D-2 below summarizes the van Genuchten fitting parameters and correlation confidence for the <br /> eight soil cores samples with air-water capillary drainage test results. <br /> Table D-2: Van Genuchten "N" and "a" and R-squared values generated from the RETC model. <br /> Soil Core Sample Soil Moisture Van Genuchten N Van Genuchten a R-Squared Values <br /> Retention Model <br /> LIF-06-13.25' Mualem 213 0.00427 0.9889 <br /> LIF-10-10.9' Mualem 1.95 0.00618 0.9916 <br /> LIF-25-10.85' Mualem 2.10 0.00674 0.9973 <br /> LIF-02-10.85' Mualem 2.27 0.00299 0.9829 <br /> 1. Used RETC results for MW-25 Pore Velocity Calculations;matched based on GSA results. <br /> The RETC program was also run under the Brooks and Corey capillarity model, and outputs shown in <br /> Figures C-1 and C-8 were generated. The displacement head pressure is the pressure (P) reached when <br /> the water content curve fit (WC-fit)value equals 1. <br /> Observed abd fitted data <br /> ------------------------ <br /> ------------------------ <br /> NO P log-P LTC-obs LTC-fit LTC-dev <br /> 1 .1000E-04 -5.4444 1.0000 1.4444 .4000 <br /> 2 .4950E+01 .6946 1.0000 1.0000 .0000 <br /> 3 .1110E+02 1.0453 1.0000 1.0000 .0000 <br /> 4 .1980E+02 1.2967 1.0000 1.0000 .0000 <br /> 5 .3100E+02 1.4914 .9910 1.0000 -.0090 <br /> 6 .4460E+02 1.6493 .9820 1.0000 -.0180 <br /> 7 .6070E+02 1.7832 .9730 1.0000 -.0270 <br /> 8 .7920E+02 1.8987 .9600 1.0000 -.0400 <br /> 9 .1240E+03 2.0934 .9370 1.0000 -.0630 <br /> 10 .2090E+03 2.3201 .8920 .9105 -.0185 <br /> 11 .3170E+03 2.5011 .8290 .8093 .0197 <br /> 12 .4950E+03 2.6946 .7630 .7354 .0276 <br /> 13 .1114E+04 3.0469 .6490 .6572 -.0082 <br /> 14 .1981E+04 3.2969 .5830 .6275 -.0445 <br /> Figure D-1: LIF-06 (12.35 ft bgs) RETC output of Brooks and Corey capillarity model, showing hd=124 <br /> cm. <br />
