Tronçon principal de la rivière Athabasca - bathymétrie, région des sables bitumineux

On sait que les sédiments du lit du cours inférieur de l’Athabasca se déplacent et migrent en aval. La modélisation numérique de la quantité et de la qualité de l’eau (y compris les matières en suspension) exige de connaître précisément la géométrie de la section transversale du lit de la rivière dans la zone d’étude. Avant 2012, cette connaissance était limitée pour le cours inférieur de l’Athabasca, ce qui restreignait l’exactitude et l’efficacité de la modélisation. Afin de mieux comprendre la dynamique des sédiments du lit dans cette partie de la rivière et pour aider à élaborer le modèle (p. ex. étalonnage et validation de l’érosion, du transport et du dépôt des sédiments et du bitume), nous avons recueilli des données de bathymétrie par secteurs à haute résolution d’une rive à l’autre pendant les saisons d’eau libre de 2012 à 2014, sur une distance d’environ 115 km entre Fort McMurray et l’embouchure de la rivière Firebag. Les données sont présentées sur des tronçons fluviaux de 2 km et dans 1) un fichier KMZ, qui donne une représentation visuelle de la zone visée et 2) un fichier contenant une grille détaillée qui renferme toutes les coordonnées x, y et z à une résolution de 0,5 m. Les données sont très utiles à la modélisation, mais il faut se rendre compte qu’elles ne donnent qu’un « instantané » et ne reflètent pas la géométrie actuelle du lit du cours inférieur de l’Athabasca, qui change continuellement. De plus, et comme il a été indiqué, elles ne peuvent servir à la navigation.
