The design of the DGR stormwater management system and the placement of the DGR surface facilities and shafts within potential siting areas must consider the range of credible storms for the watershed. [...] The location of the study site in the upstream areas of the catchments also minimize the flooding potential due to a release of impounded water. [...] Each catchment element must have a surface area where precipitation occurs, the selection of which hydrologic processes are simulated by the model was made based on the characteristics of the rainfall distributions of interest and the scope of this project. [...] Details of the MIFM and its application are included in Chapter 8 of the MTO Drainage Management Manual (1997), while the parameters that were applied to the method for the Revell Site are shown in Table 8. [...] Another way to explain this is to mention that the 1-day PMP is based on the analysis of one day precipitation records which include the average rainfall for each day, instead of its maximum, and therefore the factor is used to bring the daily averages to a maximum for the day such as the 24-hr PMP.
