Horizontal saturated conductivity1 and specific yield2 of geologic materials. Sources:Duffield; Morris and Johnson
Link to this table
| Material | Range Ksat (m/s)3 | Typical Ksat (m/s) | Range specific yield | Typical specific yield |
|---|---|---|---|---|
| Gravel | 3×10-4 to 3×10-2 | 3×10-3 | 0.21-0.28 | 0.24 |
| Coarse sand | 9×10-7 to 6×10-3 | 5×10-5 | 0.26-0.30 | 0.26 |
| Medium sand | 9×10-7 to 5×10-4 | 1×10-5 | 0.26-0.30 | 0.26 |
| Fine sand | 2×10-7 to 2×10-4 | 5×10-6 | 0.20-0.30 | 0.21 |
| Silt, loess | 1×10-9 to 2×10-5 | 9×10-7 | ||
1vertical saturated conductivity is considered to be one-tenth the value of horizontal saturated conductivity.
Superscript textSpecific yield is expressed here as a fraction. It is often reported as a percentage in the literature.
