Quantity of Seepage Formula

Equation for calculate quantity of seepage is,

Q = k × (n_f / n_d) × h_t × L

• k - effective coefficient of permeability which is √ k_maxk_min
• n_f - number of flow channels of net
• n_d - number of equipotential drops of net
• h_t - head difference between headwater and tail water
• L - length of dam to which the flow net applies
• Q - quantity of seepage in length of dam under consideration
