Description

The Canmore Flood Risk Mapping Study was conducted as part of the Canada-Alberta Flood Damage Reduction Program to prepare flood risk maps for a 20 km reach of the Bow River from the Banff National Park boundary, through the Town of Canmore,to downstream of Dead Man Flat. This study is concerned with only surface flooding caused by open-water floods. Potential flooding because of groundwater was not investigated. A review of historical flooding int he study area indicates that recent flood events, including the 1974 flood, have return periods lower than five years based on the hydrologic assessment by Alberta Environment, Hydrology Branch. The review also indicates that ice-related flooding has rarely occurred through the Town of Canmore.

Description

This study determines flood magnitudes for the North Saskatchewan River at Edmonton. Both natural and regulated annual maximum flood flows are examined in the assessment of the frequency of occurrence of future flood peak flow rates. Recorded flows and water levels within the North Saskatchewan River basin above Edmonton form the basis of the analyses. Several frequency distributions were applied to the annual flood discharge data and the most applicable distribution was selected. The results of the analyses reflect the most current information and methodologies available to determine flood frequency estimates.
