Horton's equation of infiltration capacity
WebHorton's equation (Note that this equation assumes an infinite water supply at the surface, that is, it assumes saturation conditions at the soil surface). f p (t)=f c+(f o−f c)e −kt (1) For this soil, the asymptotic or final equilibrium infiltration capacity is f c = 0.75 cm/h; and the initial infiltration capacity is f o = 5 cm/h.

Kostiakov model: Kostiakov (1932) proposed an equation to calculate cumulative infiltration (1) F = a t b where F = cumulative infiltration capacity, a and b are constants with a > 0 and 0 < b < 1. The parameters in the Kostiakov model are determined from log ( F ...

WebOct 27, 2024 · Horton’s equations: Horton expressed the decay of infiltration capacity with time as an exponential decay f t = f c + (f 0 - f c) e -kt for 0 < t < t c where, f t = Infiltration … WebInfiltration is the process in which water enters into soil and the rate at which water entering into soil is known as infiltration rate. Under the ponding condition, infiltration rate decreases exponentially, and it can be represented by Horton equation. According Horton’s equation,
WebHorton gave the following mathematical expression to find out the value of infiltration capacity at any time: f p = f c + (f o – f c) e- Kt Where f p is infiltration capacity. ADVERTISEMENTS: f o is infiltration rate at the beginning of storm. f c is constant infiltration rate which is achieved after the soil profile becomes saturated.
