Webfinal, steady state rate of infiltration that largely determines the amount of surface runoff that is generated. The calculation of infiltration at a point combines the physical conservation of mass (water) principle expressed through the continuity equation with quantification of unsaturated flow through soils, expressed by Darcy's equation. WebMar 3, 2024 · Horton's infiltration equation is given by, f t = f c + ( f 0 − f c) e − k t Where, f t is infiltration capacity at any time t, f 0 is initial infiltration capacity, f c is final infiltration capacity, K is Horton’s decay coefficient. And, total infiltration amount between any time interval t 1 and t 2 is given by, F = ∫ t 1 t 2 f t d t
Web(30 pts) The initial rate of infiltration of a watershed is estimated as 2.1 in/hr, the final capacity is 0.2 in/hr, and the time constant, k, is 0.4 hr-1.
