Question 3\ Use the Green-Ampt method to compute the infiltration rate and cumulative infiltration for a silty clay soil (

\\\\eta =0.479,\\\\psi =29.22cm,K=0.05c(m)/(h)r

, at 0.25-hr increments up to

4hr

from the beginning of the infiltration. Assume an initial effective saturation of 25 percent, an effective porosity of 0.423 , and continuous ponding. Enter the infiltration rate (cm/hr) at time

4hr

.

Use the Green-Ampt method to compute the infiltration rate and cumulative infiltration for a silty clay soil ( n=0.479,=29.22cm,K=0.05cm/hr ) at 0.25 - hr increments up to 4hr from the beginning of the infiltration. Assume an initial effective saturation of 25 percent, an effective porosity of 0.423 , and continuous ponding. Enter the infiltration rate (cm/hr) at time 4hr
