Description

Flood studies include detailed engineering reports and flood maps. The engineering reports are typically technical in nature and document the data, assumptions, and results of the hydrologic and hydraulic analyses required to create flood maps. Flood maps are created by combining hydraulic model results for different sized floods with high-accuracy ground information. Flood maps identify where water will flow during a flood, and what land could be flooded during different sized floods. Most flood maps focus on floods caused by high river flows when water escapes the river channel, most often experienced in spring or following summer rainstorms, but they can also show areas at risk from ice jam floods or document the extent of historic floods.Flood inundation maps show areas at risk for different sized floods, including ice jam floods in some communities, and identify areas protected by flood berms. Because they map a wide range of floods, they are most often used for emergency...

Flood frequency analysis : North Saskatchewan River at Edmonton

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... More ≫

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.

Description

This report discusses channel improvement alternatives along Cardinal Creek, with the objective of providing flood relief so that the floodplain lands can be used for agricultural purposes. Several alternatives are examined, with the 1:10 year return flood as the design discharge. It was found that the work required to increase the channel capacity to the 1:10 year flood discharge would cost in excess of $1 million. It is, therefore, recommended that all beaverdams and abandoned bridges be removed completely from the creek, and that the channel be cleared of brush. With these works, the extend and frequency of overbank flooding would be reduced significantly. Clearing and brushing would be required annually.

Description

In 1962 the Hydrology Division of the Department of Water Resources, in response to a request to the Department of Water Resources from the City of Calgary City Engineer, began a study of the potential flooding danger along Elbow River in an attempt to delineate the areas which would likely be under water for various probabilities of flood occurrence.
