Flow net construction
WebOne of the methods to estimate this quantity of water seepage is flow net. 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. 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.
