A rainfall$-$runoff routing model was run for the $10\%$ AEP design rainfalls with durations $1$ hr$,2$ hrs$,3$ hrs$,4\mathrm{.}5$ hrs$,6$ hrs$,9$ hrs$,12$ hrs$,18$ hrs and $24$ hrs$,$ for a catchment located on the East Coast $($North$).$ Ten rainfall temporal patterns were considered in the model runs, as recommended by the AR&R$2019.$ The ensemble results are shown below. Which peak flow should be taken as the $10\%$ AEP flow?
