Determination of coefficient of permeability by means of afield pumping test can be done for
In a soil deposit of three layers of equal thickness, the permeabilities of first, second and third layers are in the ratio of 1 : 2 : 3. The ratio of average permeability in horizontal direction (k_{h}) to that in the vertical direction (k_{v}) will be
Rise of water table above the ground surface causes:
The water level in a lake is 5 m above the bed. The saturated unit weight of the lake bed soil is 20 kN/m^{3}. The unit weight of water is 10 kN/m^{3}. The effective vertical stress at 5 m depth below . the lake bed is
Due to rise in temperature, the viscosity and the unit weight of the percolating fluid are reduced to 60% and 90% respectively. If other things remain constant, the coefficient of permeability
Consider the following statements:
Capillary water in soils
1. Causes negative pore water pressure.
2. Reduces effective pressure
3. Increases bearing capacity
4. Reduces bearing capacity
Which of these statements are correct?
Effective stress on soil:
In a fallinghead permeability test, the time taken for the head to fall from 27 cm to 3 cm is 10 minutes, if the test is repeated with the same initial head, i.e., 27 cm, what time would it take for the head to fall to 9 cm?
The ratio of Darcy’s coefficient of permeability to porosity is known as:
The soils most susceptible to liquefaction are
