A small catchment area of 12 ha has a runoff coefficient of 0.45. For a design storm the 30‑minute rainfall intensity is 15 mm h\(^{-1}\). Using the rational method \(Q = C i A\), where \(Q\) is the peak discharge (m\(^3\) s\(^{-1}\)), \(i\) is the rainfall intensity in mm h\(^{-1}\) and \(A\) is the catchment area in square metres, calculate the peak discharge.
