Question

The configuration of flow nets depends upon

• A. the permeability of the soil
• B. the difference in the head between upstream and downstream sides
• C. the boundary condition of flow
• D. the amount of seepage that takes place

Answer 1

The correct option is C the boundary condition of flow

A flow net is a graphical solution to the equations of steady groundwater flow. A flow net consists of two sets of lines which must always be orthogonal (perpendicular to each other): flow lines, which show the direction of groundwater flow, and equipotential lines (lines of constant head), which show the distribution of potential energy.
