MECHANISMS AND KINEMATICS OF RIVER VALLEY LANDSLIDES IN EDMONTON (2009)
A study of three translational landslides along the North Saskatchewan River Valley in Edmonton is presented in this paper. The major focus is on kinematics and mechanisms of deep seated landslides in bedrock of the Upper Cretaceous Horseshoe Canyon Formation. The study found that the river valley landslides are caused by a combination of several factors, including toe erosion by the river, the effects of residential development behind the slope crests including the rise of groundwater levels, and softening of the bedrock materials at the valley wall. The landslides developed in stages starting as a minor toe failure and gradually retrogressing upslope. Development of landslide stages observed in the North Saskatchewan River Valley can be described as follows.
