I'm sorry I didn't get this out yesterday, but I had something else to do that couldn't wait. Guelph loam For this soil, when w=1 and theta0=.22, there is no ponding nor runoff. When w=1, 2 and theta0=.32, there is no ponding nor runoff. Phi=.523 Khsat=1.32 For theta0=.32 and w=3 F(t)=14.628 total runoff=3.372 runoff ratio=.1873 For theta0=.42 and w=2 F(t)=11.46 total runoff=.54 runoff ratio=.045 w=3 theta0=.42 f(t) time 3.00 0 3.00 0.847 Time of ponding 2.74 1.007 2.39 1.401 2.17 1.841 2.03 2.318 1.93 2.823 1.85 3.353 1.79 3.901 1.75 4.466 1.71 5.046 1.68 5.637 1.66 6.000 Ida silt loam Phi=.53 Khsat=0.105 w=1 theta0=.22 f(t) Time 1.00 0 1.00 .268 time of ponding .90 .302 .70 .428 .58 .585 .34 1.753 .26 3.432 .24 4.629 .22 5.493 .22 5.717 .22 5.944 .22 5.989 .22 6.000 w=2 theta0=.22 F(t)=2.1336 total runoff=9.866 runoff ratio=.822 w=1 theta0=.32 F(t)=1.8277 total runoff=4.1723 runoff ratio=.6954 w=2 theta0=.32 F(t)=1.8406 total runoff=10.1594 runoff ratio=.8466 f(t) time 2.00 0 2.00 .043 time of ponding 1.73 .051 .92 .134 .65 .267 .51 .442 .43 .656 .38 .906 .31 1.498 .27 2.198 .21 4.318 .19 5.992 .19 6.000 w=3 theta0=.32 F(t)=1.8428 total runoff=16.1572 runoff ratio=.8976 w=2 theta0=.42 F(t)=1.466 total runoff=10.534 runoff ratio=.8778 w=3 theta0=.42 f(t) Time 3.00 0 3.00 .010 time of ponding 2.23 .014 1.81 .019 .96 .059 .39 .431 .28 1.057 .21 2.323 .19 3.324 .18 4.420 .17 4.997 .17 5.592 .16 6.000 That is everything you asked for as far as I can tell.
