p_parm Function This function calculates the p-parameter from Table 1 of Tobiason and O'Melia (1988). The p-parameter is based on soil porosity.

1	p_parm(POR = 0.21)

POR

porosity. Defaults to a value of 0.21. The value of 0.21 is the average for medium sand as reported by Johnson (1967)

p_parm(POR = 0.3)
[1] 0.887904

p_parm(POR = 21)
[1] "Error: Porosity value must be less than 1"
