Clay liner breakthrough time for leachate calculator - formula & step by step calculation to measure the amount of breakthrough time for leachate to penetrate a clay liner. t = [(d2η) / K(d + h)]. Thickness of clay liner d in m, coefficient of permeability K in m/year, porosity η in percentage & hydraulic head h in m are the key elements of this calculation. The typical porosity values vary from 0.1 to 0.3 for the clays with permeability coefficient values from 10-6 to 10-8.

Formula

In environmental engineering, the below formula is used to calculate the breakthrough time for leachate to penetrate a clay liner. The step by step calculation for each set of inputs let the users to understand how to perform such landfill clay liner penetration time calculations manually.
