The infiltration capacity of a soil follows the Horton's exponential model, f = c. During and experiment, the initial infiltration capacity was observed to be 200 mm/h. After a long time, the infiltration capacity was reduced to 25 mm/h. If the infiltration capacity after 1 hour was 90 mm/h, the value of the decay rate constant, k (in 11', up to two decimal places) is____
  • a)
    0.37
  • b)
    0.1
  • c)
    0.99
  • d)
    0.02
Correct answer is option 'C'. Can you explain this answer?

The infiltration capacity of a soil follows the Hortons exponential mo...
Horton's infiltration capacity
f = fc + (f0−fi)e−∞t
fε = ultimate infiltration capacity = 25 mm/hr
f = Initial infiltration capacity = 200 mm/hr
f = Infiltration capacity = 90 mm/hr
f = fc + (f0−fi)e−∞t
90 = 25 + (200 - 25) e-∞x1
175e-x = 65
E-x = 0.371
∝ = 0.9915; ∝ = 0.99/hou!
