Functions¶
calc_ptf_jabro1992¶
Estimate saturated hydraulic conductivity from silt, clay, and bulk density.
static inline double calc_ptf_jabro1992(double silt, double clay, double bulk_density);
Parameters¶
| Name | Direction | Description |
|---|---|---|
silt | in | Silt content, 0.002-0.05 mm. (%) |
clay | in | Clay content, <0.002 mm. (%) |
bulk_density | in | 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.
