Coefficient of percolation formula

WebAccording to Darcy’s law, for laminar flow conditions, the velocity of flow is directly proportional to the hydraulic gradient ‘i’. V α i. .’. V = Ki. The proportionality constant, k between v and i is called Darcy’s coefficient permeability. When i = 1 we have K= V. Thus, the coefficient of permeability can also be defined as the ... WebTable 3 presents coefficients used in the "Rational Formula" for various surface conditions. By applying the coefficients to the mean monthly precipitation, an estimate of "mean monthly surface runoff" can be calculated. ... Percolation and generation of leachate will most likely follow a pattern similar to that of the precipitation.
