Flood Flow Statistics Geographic Information (recommended)
Data Format(s): MS Access DatabaseAbstract:
In 2014, as part of its hydrological data program, the Spatial Data Infrastructure Unit of the Ontario Ministry of Natural Resources and Forestry (OMNRF) generated single-station flood frequency estimates for the Water Survey of Canada’s (WSC) HYDAT gauges in the Great Lakes – St. Lawrence watershed systems that lie within the Province of Ontario. The resultant statistics include the flood magnitude with recurrence intervals of 1:2, 1:2.33, 1:5, 1:10, 1:20, 1:25, 1:50, 1:100, 1:200 and 1:500 years. The flood magnitude statistics can be used for applications such as floodplain delineation and design of hydraulic structures. The estimated flow statistics are in MS Access Personal Geodatabase format and will be included in the Ontario Flow Assessment Tool web application in the future.
