इष्टतम नमी सामग्री (OMC) को मिट्टी की उस नमी सामग्री के रूप में परिभाषित किया जाता है जिस पर:

For a stratified soil mass, the permeability coefficients are k1 = k, k2 = 2k, and k3 = 3k, whereas the layer thicknesses are H1 = h, H2 = 2h, and H3 = 3h. Find the ratio of equivalent permeability in the horizontal direction to that in the vertical direction.

How does a rise in the water table affect the bearing capacity of soil?
