Infiltration cont.
… Storms that have high intensity levels may also cause excess precipitation because the intensity (inches per hour) may exceed the current infiltration capacity (inches per hour).
… periods of low rainfall or no rainfall will allow the soil to "recover" and increase the capacity to infiltrate water.…
Infiltrated water replenishes soil moisture and groundwater reservoirs. Infiltrated water may also resurface to become surface flow.
… attempt to account for infiltration by estimating excess precipitation (the difference between precipitation and excess being considered infiltration), for example, the Soil Conservation Service (SCS) runoff curve number method
