Webthat of the calculation of a index (see section 4.3.2). The rainfall hyetograph is integrated to calculate the total rainfall volume. Likewise, the runoff hydrograph is integrated to calculate the runoff volume. The infiltration volume is obtained by subtracting runoff volume from rainfall volume. The average infiltration rate is WebThe ratio on the right hand side of the Green-Ampt equation represents the hydraulic gradient. Since the ponding depth, H 0, and the pressure potential at the wetting front, H f, are treated as constants, the hydraulic gradient gets smaller as L f gets larger, i.e. as the wetting front moves farther away from the soil surface.
