Soil Hydraulic Conductivity: GC-CL
Soil hydraulic conductivity (permeability) and drainage classification by USCS soil type — typical, min, and max values in cm/s
| uscs type | description | drainage class | hydraulic conductivity cm s (cm/s) | hydraulic conductivity max cm s (cm/s) | hydraulic conductivity min cm s (cm/s) |
|---|---|---|---|---|---|
| GC-CL | Clayey gravel (dual symbol) | poor | 0.00001 | 0.0001 | 0.000001 |
