An anisotropic soil deposit has coefficient of permeability in vertical and horizontal directions as kz and kx, respectively. For constructing a flow net, the horizontal dimension of the problem’s geometry is transformed by a multiplying factor of

• A. \(\frac{{{k_z}}}{{{k_x}}}\)
• B. \(\frac{{{k_x}}}{{{k_z}}}\)
• C. \(\sqrt {\frac{{{k_z}}}{{{k_x}}}} \)
• D. \(\sqrt {\frac{{{k_x}}}{{{k_z}}}}\)
