Hydrology and Runoff

The total cumulative depth of infiltration $F(t)$ during time duration $t$ according to Horton's equation is:

Options:

• (A) $F(t) = f_c t + \frac{f_0 - f_c}{k}(1 - e^{-kt})$
• (B) $F(t) = (f_0 + f_c) t / 2$
• (C) $F(t) = f_c t + (f_0 - f_c) e^{-kt}$
• (D) $F(t) = f_0 t - k t^2$
