Question

For any time step, when the effective precipitation \( (P_E) \) exceeds infiltration \( (I) \), the total rainfall excess \( (TRE) \) can be computed as:

• A. \( TRE = (P_E - I) \)
• B. \( TRE = (P_E + I) \)
• C. \( TRE = (P_E - I)^2 \)
• D. \( TRE = (P_E + I)^2 \)

Hint:

Rainfall excess = Effective rainfall - Infiltration, if \( P_E>I \).

Answer 1

The Correct Option is A

When effective precipitation \( P_E \) exceeds infiltration \( I \), the total rainfall excess (TRE) is simply the remaining amount of water: \[ TRE = P_E - I \] This is a direct hydrological principle.
