Canadian Dam Association Bulletin - Winter 2018 - 11

ABSTRACT
The devastating floods during June 2013 raised awareness of the risk to infrastructure. Stantec
engaged Applied Weather Associates (AWA) to develop PMP values for the Elbow River basin
upstream of Glenmore Reservoir and the City of Calgary to understand the flood hydrology
of the Elbow River basin and develop design criteria for the Springbank Off-Stream Storage
Project. PMP studies have been completed in the region from the 1980's through the early 2000's.
However, these included limited storm data, outdated methodologies, and did not include several
recent extreme storm events, including June of 2005 and June of 2013. AWA has been completing
PMP studies for more than 20 years across North America. The data, knowledge, and methods
developed during previous and ongoing PMP studies were applied by AWA to produce reliable,
reproducible and scientifically defensible PMP values. This work included important collaboration with flood hydrologists and oversight from an independent review board. The direct
involvement with hydrologists and other experts ensured appropriate application of the results
in the process of determining reasonable site-specific PMP for the basin. This presentation will
detail how the PMP was developed in a region of complex terrain and how appropriate applications were provided for a basin with a unique set of requirements for the hydrologic modeling.

RÉSUMÉ
Les inondations dévastatrices de juin 2013 ont causé une prise de conscience quant au risque
pour les infrastructures. Stantec a engagé Applied Weather Associates (AWA) pour développer
des valeurs PMP pour le bassin de la rivière Elbow en amont du réservoir Glenmore et de la
Ville de Calgary afin de comprendre l'hydrologie des crues du bassin de la rivière Elbow et de
développer des critères de conception pour le projet Springbank Off-stream Storage. Des études
PMP ont été réalisées dans la région à partir des années 1980 jusqu'au début des années 2000.
Cependant, celles-ci comprenaient des données partielles de tempête ainsi que des méthodes
obsolètes et elles ne considéraient pas plusieurs événements récents de tempêtes extrêmes, y
compris celles de juin 2005 et de juin 2013. La firme AWA a réalisé depuis plus de 20 ans des
études PMP en Amérique du Nord. Les données, les connaissances et les méthodes développées
au cours des études de PMP antérieures et actuellement en cours ont été appliquées par AWA
afin de produire des valeurs de PMP fiables, reproductibles et scientifiquement défendables. Ce
travail comprenait une collaboration étroite avec des hydrologues pour les inondations et une
supervision par un comité d'experts indépendants. L'implication directe avec les hydrologues et
d'autres experts a assuré l'application appropriée des résultats dans le processus de détermination
de la PMP appropriée pour ce bassin. Ce document détaillera comment la PMP a été développée
dans une région de terrain complexe et comment les applications appropriées ont été fournies
pour un bassin avec un ensemble unique d'exigences quant à la modélisation hydrologique.
