Consider a two-dimensional flow through isotropic soil along

{x}

-direction and

{z}

-direction. If

h

is the hydraulic head, the Laplace's equation of continuity is expressed as

Solution:

\;{6^{2} h}/{d x^{2}}+\;{6^{2} h}/{6 z^{2}}=0

For homogeneous isotropic soils, the laplace's equation of continuity is expressed as:

\;{8^{2} h}/{d x^{2}}+\;{8^{2} h}/{d z^{2}}=0
