Horton infiltration decay rate
WebOct 1, 2024 · The original Horton equation ( Horton, 1939) is given by: (1) f p t = f c + f 0 - f c e - k t where f p t is the potential infiltration capacity at time t (L/T); f c is the final equilibrium infiltration capacity (L/T); f 0 is the initial infiltration capacity (L/T); and k is a decay parameter (T −1 ). http://alanasmith.com/theory-Calculating-Effective-Rainfall-The-Horton-Equation.htm
