DFCCIL_CE _Quiz 48

The water level in a lake is 5 m above the bed. The saturated unit weight of the lake bed soil is 20 KN/m³. The unit weight of water is 10 KN/m³. The effective vertical stress at 5m depth below the lake bed is:

Capillary water in soils

The quantity of seepage of water in a soil medium is

When applying Darcy’s law to soils, it is assumed that the

The ground conditions at a site are:

Water table is at ground level.

Water content = 20%

Specific gravity = 2.6

Unit weight of water = 10 kN/m²

Then effective stress, at a point 4 m below ground level is

In a Soil deposit of three layers of equal thickness, the permeabilities of first, second and third layers are in the ratio 1:2:3 . The ratio of average permeability in horizontal direction (K_h) to that in the vertical direction (K_v) will be:
