An anisotropic soil deposit has coefficient of permeability in vertical and horizontal directions as $k_z$ and $k_x$, respectively. For constructing a flow net, the horizontal dimension of the problemâ€™s geometry is transformed by a multiplying factor of $\sqrt{\dfrac{k_z}{k_x}} \\$ $\sqrt{\dfrac{k_x}{k_z}} \\$ $\dfrac{k_x}{k_z} \\$ $\dfrac{k_z}{k_x}$

A non-homogeneous soil deposit consists of a silt layer sandwiched between a fine-sand layer at top and a clay layer below. Permeability of the silt layer is $10$ times the permeability of the clay layer and one-tenth of the permeability of ... third of the thickness of the clay layer. The ratio of equivalent horizontal and equivalent vertical permeability of the deposit is _________.

GATE Civil 2013 | Question: 36
The soil profile below a lake with water level at elevation $=0$ m and lake bottom at elevation $=-10$ m is shown in the figure, where $k$ is the permeability coefficient. A piezometer (stand pipe) installed in the sand layer shows a reading of $+10$ m elevation. Assume that the ... $2.0 \times 10^{-6}$ $1.0 \times 10^{-6}$ $0.5 \times 10^{-6}$

GATE Civil 2012 | Question: 36
Two soil specimens with identical geometric dimensions were subjected to failing head permeability tests in the laboratory under identical conditions. The fall of water head was measured after an identical time interval. The ratio of initial to final water heads for the test ... water heads in the test involving the second specimen is $3.05$ $3.80$ $4.00$ $6.25$

Three soil specimens (Soil $1$, Soil $2$ and Soil $3$), each $150$ mm long and $100$ mm diameter, are placed in series in a instant head flow set-up as shown in the figure. Suitable screens are provided at the boundaries of the specimens to keep them intact. The values of ... and $0.03$ cm/s, respectively. The value of $h$ in the set-up is $0$ mm $40$ mm $255$ mm $560$ mm
