WebDetermining Seepage Discharge: Let b and L be the dimensions of the field and Δh be the head drop through this field. Also, let Δq represent the discharge passing through the flow channel, per unit length of structure (perpendicular to paper). Then from Darcy’s law, we can write – Where k = permeability of the soil. WebNow we can draw the flow net for the seepage flow by the method we have discussed in the flow net topic and the seepage quantity can be calculated using this formula. We can also …
