Flow Net and its Properties

Flow Net

The flow net is a network formed by the flow lines and is the pattern which shows the path of flow as well as the dissipation of potential in a system of seepage through a layer of soil.

8 Properties of Flow Net

The following are the 8 properties of flow net:

1.  The flow lines and equipotential lines  meet at right angles to each other
2.  Two flow lines never cross each other.
3.  Two equipotential lines never cross each other.
4.  Flow and equipotential lines are smooth curves.
5.  The quantity of water flowing through each flow channel is the same.
6.  The same potential drop occurs between the successive equipotential lines.
7.  Two flow lines or equipotential lines never start from the same point.
8.  The smaller the field, the greater will be the hydraulic gradient.
