Coefficient of permeability:
- The coefficient of permeability of soil describes how easily a liquid will move through the soil.
- It is also commonly referred to as the hydraulic conductivity of the soil.
- This factor can be affected by the viscosity, or thickness(fluidity) of a liquid and its density.
For the different soil types as per grain size, the orders of magnitude of permeability are as follows:
|
Type of soil |
Permeability (cm/s) |
|
Gravel |
1 |
|
Coarse sand |
1 to 0.1 |
|
Medium sand |
10-1 to 10-2 |
|
Fine sand |
10-2 to 10-3 |
|
Silty sand |
10-3 to 10-4 |
|
Silt |
10-5 |
|
Clay |
10-7 to 10-9 |
