A flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. The construction of a flow net is commonly used to solve groundwater flow problems where analytical solutions are impractical due to complex geometry. It is widely applied in civil engineering, hydrogeology, and soil mechanics, particularly for analyzing seepage beneath hydraulic structures such as dams and sheet pile walls. A flow net consists of a grid formed by drawing a series of equipotential lines and flow lines, making it an important tool for analyzing two-dimensional irrotational flow problems. The flow net technique is therefore a graphical method used to represent and study groundwater flow behavior (Wikipedia).
