# What is Flow Net in geotechnical engineering?

**Flow Net**– Properties and Applications. A

**Flow net**is a graphical representation of

**flow**of water through a soil mass. It is a curvilinear

**net**formed by the combination of

**flow**lines and equipotential lines.

**Flow**lines represent the path of

**flow**along which the water will seep through the soil.

Keeping this in consideration, what is meant by flow net?

A **flownet** is a graphical representation of two-dimensional steady-state groundwater **flow** through aquifers. Construction of a **flownet** is often used for solving groundwater **flow** problems where the geometry makes analytical solutions impractical.

Subsequently, question is, what is quick sand condition? **Quick sand condition** or boiling **Quick sand condition** is a **condition** of flow, not a type of soil, in which a vertical upward seepage flow causes floating **condition** of a particle in cohesion less soil such as **Sand** and fine gravel . ? There is also a pressure in downward direction due to submerged weight of soil.

In this regard, what are the properties of flow net?

**Properties of Flow net**: **Flow** nets must satisfy the boundary conditions of **flow** field. Quantity of water flowing through each **flow** channel is the same. The potential drop in any two consecutive equal potential lines is same/constant. **Flow** lines and equal potential lines are smooth curves.

What is equipotential line?

**Equipotential lines** are like contour **lines** on a map which trace **lines** of equal altitude. In this case the "altitude" is electric potential or voltage. **Equipotential lines** are always perpendicular to the electric field. In three dimensions, the **lines** form **equipotential** surfaces.
