Calculating Deep percolation

Description

Calculating Deep percolation

Usage

cal_DeepPercolation(Wa, Wfc, a, b, t)

Arguments

Wa	actual soil water storage in the root zone (mm)
Wfc	soil water storage to maximum root depth (Zr ) at field capacity (mm)
a	A water storage value comprised between WFc and Wa at saturation.
b	b<-0.0173 for soils draining quickly.Otherwise b>-0.0173.
t	time after an irrigation or rain that produced a storage above field capacity (days)

Value

A vector for deep percolation(mm/day).
