Downstream Transition of River Ice Jams

Journal of Hydraulic Engineering, 1986
The granular mass theory of river ice jams is extended to their downstream transition as a means of improving understanding of conditions at jam toe. The theory is coupled with the equations of motion under, and seepage through, the jam and the resulting differential equations are solved numerically.

Numerical computation of river ice jams

Canadian Journal of Civil Engineering, 1993
A numerical model called RIVJAM has been developed to compute the configuration of and water levels caused by ice jams of the "wide" kind, under natural stream conditions and regardless of whether the jam has attained its full potential, known as equilibrium.

The shapes of glacial and ice-jam cobbles

Journal of Sedimentary Research, 1936
Abstract A total of 503 glacial cobbles and boulders in seven series were measured and classified as to type of rock, shape, character and degree of surface markings, and the like. One hundred and fifteen ice jam roundstones of various sizes were likewise measured and classified, in five different series.

ASSESSING ASSUMPTIONS IN ICE JAM FLOOD HAZARD MAPPING: MODEL CHOICE AND ICE JAM VOLUME

Ice-jam flooding is a major driver of extreme water levels in cold-region rivers and represents a major challenge for flood hazard mapping. This thesis investigates two influential assumptions in ice jam flood mapping studies: the choice of hydraulic model and the representation of ice-jam volume.
