If S is the potential infiltration, P is rainfall in cm in a drainage of a soil with fair pasture cover, the
direct run off Q in cm is given by
(A) Q = (P - 0.1 S)²/(P + 0.4 S)
(B) Q = (P - 0.2 S)²/(P + 0.6 S)
(C) Q = (P - 0.2 S)²/(P + 0.8 S)
(D) Q = (P - 0.2 S)²/(P + 0.2 S)
direct run off Q in cm is given by
(A) Q = (P - 0.1 S)²/(P + 0.4 S)
(B) Q = (P - 0.2 S)²/(P + 0.6 S)
(C) Q = (P - 0.2 S)²/(P + 0.8 S)
(D) Q = (P - 0.2 S)²/(P + 0.2 S)
