Flow net construction
WebThe flow net shown in Figure 10.10(a) is for a homogeneous, isotropic medium. The hydraulic heads, pressure heads, and fluid pressures (or pore pressures) that exist at any point in the system are independent of the hydraulic conductivity of the medium, although the flow velocities and quantities of leakage would of course depend on this parameter. WebFigure 10 – The appropriate number of head drops (spaces between equipotential lines) and flow tubes (spaces between flow lines) are determined by following the rules for drawing a flow net. This flow net has 14 head drops and 3 flow tubes. This flow net drawing began with two internal flow lines, creating three flow tubes beneath the dam.

We have already discussed the method of flow net construction when the flow was confined that means all the boundary conditions of the flow were known to us. But seepage through an earth dam is the case of unconfined flow of which the upper boundary is not known.
WebFlow Net. Figure 6-3 shows an example of flow net construction. Use this procedure to estimate seepage quantity and distribution of pore water pressures in two-dimensional flow. Flow nets are applicable for the … A flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. Construction of a flow net is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. The method is often used in civil engineering, hydrogeology or soil mechanics as a first check for problems of flow under hydraulic structures like
