inline double calc_ptf_jabro1992(double silt, double clay, double bulk_density)
Parameters¶
| Name | Description |
|---|---|
silt | Silt content, 0.002-0.05 mm. (%) |
clay | Clay content, <0.002 mm. (%) |
bulk_density | Bulk density. (g/cm^3) |
Returns¶
Saturated hydraulic conductivity. (m/s)
Note
Sand is not an input to the model.
Warning
The formula uses base-10 logarithms of silt and clay.
