According to Budhu (2011), the procedure for constructing the flownet of isotropic soils are as follows; Draw the structure and soil mass to a suitable scale. Identify impermeable and permeable boundaries. The soil–impermeable boundary interfaces are flow lines because water can flow along these interfaces.

Web1. Mark all boundary conditions, and draw the flow cross section to some convenient scale. 2. Draw a coarse net which is consistent with the boundary conditions and which has orthogonal equipotential and flow lines. As it is usually easier to visualise the pattern of flow, start by drawing the flow lines first. Download the notes.
