Problem #12
Green-Ampt Infiltration Equation
Rainfall occurs at a constant rate of 1.2 cm/hr on a loam soil.  Use the Green-Ampt method to determine the actual infiltration assuming the effective saturation se is 0.50.  Compute the following:
  1. Ponding time tp (hours)
  2. Cumulative infiltration at ponding (cm)
  3. Equivalent time origin t0 (hours)
  4. Cumulative infiltration after 30 minutes of rainfall (cm)
  5. Infiltration rate after 30 minutes of rainfall (cm/hr)
  6. Cumulative infiltration after 2 hour of rainfall (cm)
  7. Infiltration rate after 2 hour of rainfall (cm/hr)
