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 problem’s geometry is transformed by a multiplying factor of
- $\sqrt{\dfrac{k_z}{k_x}} \\$
- $\sqrt{\dfrac{k_x}{k_z}} \\$
- $\dfrac{k_x}{k_z} \\$
- $\dfrac{k_z}{k_x}$
