Problem 7.2.a) The Philip and Green-Ampt equations provide models for “infiltration capacity” (or “potential infiltration”). What assumptions are used in the development of the Philip and Green-Ampt infiltration capacity models? Clearly explain the difference between actual infiltration rate and infiltration capacity (potential infiltration). Under what specific conditions are the two the same? b) State the condition that for a given rainfall (or snowmelt) event would never generate infiltration excess runoff. This should be written in terms of the rainfall/melt rate...
