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

A 3 m thick soil stratum has 40% porosity. If the unit weight of soil at 12.2% water content is 18 kN/m3 , the total head required to cause quick sand condition is
A load of 6251 T is imposed on a footing of size 2 m × 2 m If it is to be assumed that, stress at depth "d" is spread out at an angle of 2 vertical to 1 horizontal, find out the depth 'd' at which the intensity of stress will be \({\left( {\frac{1}{9}} \right)^{th}}\) of the stress at ground level. Choose correct depth in metres from the following:
