Problem: For the Touchet Loam with the same Brooks-Corey parameter as given in Problem 1, we would like to estimate the instantaneous infiltration rate when the rainfall rate is 120 mm/day and the wetting front is 0.2m into the ground. Prior to the rain, the soil's soil moisture content is 0.201. Ks of the soil is 0.02 m/day. What if the wetting front proceeds to 1m into the ground? (hint: use Brooks and Corey to estimate the initial suction. The rest of the problem is similar to the example in the slides)
