WebSep 1, 2014 · The peaking factor given by Eq. (2) is calculated for every day of the record and for every duration t. For every duration ( t ), there will be peaking factors equal to the number of days ( N) for which hourly flow record is available. All ( N) peaking factors Pmax/min hr-t-avghr for the same ( t) were sorted in an ascending order.
