According to Robert E. Horton, the equation of infiltration capacity curve, is (where letters carry their usual meanings)

[A]. f = fc (fo - fc) ekt
[B]. f = ft - (fo - fc) e-kt
[C]. f = ft + (fo - fc) e-kt
[D]. f = f + (fo - fc) ekt

Answer: Option C

The correct answer is A.

f = infiltration capacity.
fc = value of infiltration after it reach a constant value.
fo = infiltration capacity at the start.
k = constant.
t= time from beginning of rainfall.

The correct answer is A not C.

Mallikarjun Shabad said: (Jan 20, 2018)  
C only correct but it should be f(t)=fc + (fo - fc) e-kt.

The Correct answer is A.

Teba said: (May 11, 2018)  
Yes, I agree @Mallikarjun.

Vinod said: (Sep 9, 2018)  
Yes, right @Malikarjun.

Rahul said: (Sep 20, 2018)  
According to me, B is the correct answer.

Sudhakar said: (Feb 24, 2019)  
I think A is the correct answer.

Ramyahegde said: (Mar 19, 2019)  
It is F = fc+(fo-fc)e^-kt.

Manu said: (Jul 30, 2019)  
f(t) = f(c)+(f0-fc)*e^(-kt) is the correct Horton equation.

Saqib said: (Sep 22, 2019)  
fp = fc + (fo - fc)e-kt.
where fp = the infiltration capacity (depth/time) at some time t.
k = a constant representing the rate of decrease in f capacity,
fc = a final or equilibrium capacity,
f0 = the initial infiltration capacity.
