Abstract
The deformation and state of stress at the confluence of two glacier streams are analyzed using the techniques of slip-line theory. The valley walls are assumed to be vertical parallel planes and the deformation is independent of depth. The mechanical behavior of ice is modelled by the ideal rigid/perfectly plastic material. Detailed solutions are presented for the deformation at the confluence of one or more tributaries with a main stream and of two main streams, predicting the number, position and magnitude of the bands of intense shear which emanate from some of the junction corners. The predictions of this idealized theory are compared with field data from a confluence on the Kaskawulsh Glacier, Yukon Territory, Canada.
