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:
Consider the following statements in the context of capillary pressure in soils:1. Pore water pressure is negative in capillary zone.2. Water is in tension in capillary zone.3. Capillary pressure in more in coarse grained soils.Which of the above statements are correct?
In a saturated clay layer undergoing consolidation with single drainage at its top, the pore water pressure would be the maximum at its

Groundwater flows through an aquifer with cross-sectional and of 1.0 × 104 m2 and a length of 1500 m. Hydraulic heads are 300 m and 250 m at the groundwater entry and exit points in the aquifer, respectively. Groundwater discharges into a stream at the rate of 750 m3/day. Then the hydraulic conductivity of the aquifer is
