If Q = stream flow, P = precipitation, E = evapotranspiration, S = net change in storage and T = net underground transfers, then the basic water balance equation is

[A] Q = (P + E) – ( S + T)

[B] Q = (P – E) – ( S + T)

[C] Q = (P – E) – ( S – T)

[D] Q = (P – E) – ( S – T)

Answer & Explanation
Answer: Q = (P – E) – ( S – T)
