The qualitative analysis noted that, due to the site topography and proposed layout with respect to the catchments, extreme precipitation events should be applied without reduction factors, and the catchment response to precipitation is expected to be long due to the runoff conveyed from the large upstream catchments via the Teeswater River to the study site. [...] 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 downstream areas of the catchments also minimize the flooding potential due to a release of impounded water. [...] Upon review of the MIFM methodology, the lag time for CA1 and CA2 are too long for the calculation to be applicable, and the results from the MIFM were dismissed for comparison to the hydrologic model results. [...] Given that the results of the hydrologic model and UOFM are close for CA1, the largest catchment, and produced higher peak flows for CA2, it was concluded that the hydrologic model is able to simulate flood events within the South Bruce study area for the purposes of this preliminary flood hazard assessment.
