| 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 |
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.
