Rational Method Peak Discharge

Estimate stormwater runoff peak flow rates ($Q$) from catchment basins for conveyance channel design.

Metric: Q = (C × i × A) / 360
(where Q is in m³/s, i is in mm/hr, A is in hectares)

Runoff Coefficient ($C$)

Rainfall Intensity ($i$ in mm/hr)

Catchment Area ($A$ in hectares)

Calculated Peak Discharge ($Q$): -
