Consider the following statements:1. Effective stress in a sand layer below a lake with standing water does not alter as the water level fluctuates.2. Regarding water table below the ground surface, any rise in the water table causes equal changes in both pore pressure and effective stress.3. Capillary saturation will cause the effective stress to increase.Which of the above statements are correct?

A uniform collapsible sand stratum, 2.5 m thick, has specific gravity of its sand as 2.65, with a natural void ratio of 0.65. The hydraulic head required to cause quick collapsible sand condition is
A stratum of 3.5 m thick fine sand has a void ratio of 0.7 and G of 2.7. For a quicksand condition to develop in this strata, the water flowing in an upward direction would require a head of:
A company has proposed to design a weir across a river in alluvial soil. The piezometric head at the bottom of the datum is computed as 10 m. The datum is 3 m below the floor bottom. The assured standing water depth above the floor is 2 m. The specific gravity of the floor material is 2.5. The required minimum thickness of the floor is:
