13.

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

Explanation:

No answer description available for this question.

 Silver Heaven said: (Aug 25, 2017) 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.

 Srilatha Kasturi said: (Dec 12, 2017) 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.

 Bhagwat said: (May 5, 2018) 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.
