Which of the following statement is/ are CORRECT?
1
The capillary rise in the soil above the water table will lead to the development of negative pore water pressure(PWP) and hence decreasing the effective stress of soil.
2
Even if the No. of flow lines and No. of equipotential lines changes so long as the Boundary condition is not changed, the flow net will not change.
3
If the permeability of the soil through which seepage occurs will change, the Flow net of the soil will also get changed.
4
The permeability of fully saturated soil is more than that of partially saturated soil.
