12. (Horton's equation for infiltration rate, ). One can use Horton's equation to estimate the infiltration rate of water into soil if the rainfall rate exceeds the infiltration rate. The Horton's equation states that: f = fe+ (fo-fc) x e-kt where f is the infiltration rate (cm h:¹), fe is the equilibrium infiltration rate (cm h 1), fo is the initial infiltration rate (cm h:¹), k is an empirical constant (h:¹), and t is time (h). Horton's equation can be integrated to yield an equation that represents the total volume of water that would infiltrate over a given period: V=A₁ [Fxα= 4, 16+ V = A₁ [fx dt = A₁ [lfc + (fo-fc) × e-k¹] x dt = A₂ × [fet + fo=fc (1 - e-*)] 0 where As is the unit area (1 m²) and V is the volume (m³). Sothan loamy sand has the following characteristics: fe= 6.68 cm h¹, fo = 8.81 cm h¹, k = 1.40 h ¹.

3. The Horton infiltration equation f(t) describes how the infiltration capacity (mm/hr) for the soil is changing with time as the soil becomes wetter. The accumulated infiltrated water (in mm) can be calculated using the integral of f(t), i.e., F(t). where, fo = initial infiltration capacity of dry soil (mm/hr) fc = final infiltration capacity when the soil has become saturated soil (mm/hr) k = time constant (hr4) Note that the Horton equation is only valid for ponding conditions. In a specific soil, the following parameters are known: fo = 35 (mm/hr) fc = 6 (mm/hr) k = 2 (hr 1) %3D What is the infiltration capacity after 15,30, and 60 min?
