The peak of a flood hydrograph due to a 5 -hour storm is $670 \mathrm{~m}^{3} \mathrm{~s}^{-1}$. The total depth of rainfall is $9 \mathrm{~cm}$. Assuming an average infiltration loss of $0.2 \mathrm{~cm} \mathrm{~h}^{-1}$ and a constant baseflow of $30 \mathrm{~m}^{3} \mathrm{~s}^{-1},$ the peak discharge of the 5 -hour unit hydrograph for this catchment in $\mathrm{m}^{3} \mathrm{~s}^{-1}$ is_____________
