After a few trials, the final flow net can be obtained as shown in Figure-ii-c (Nf =1.2 and Nd =5). 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.
