Erosion potential of dynamic ice breakup in Lower Athabasca River. Part I; Field measurements and initial quantification

Highlights •Can dynamic ice breakup in lower Athabasca River generate large erosional forces? •Two-season field study furnishes unique spatiotemporal variations of water level. •Calculated local water surface slopes attain extreme values. •Initial estimates of peak bed shear stress exceed all previously known values. •Extreme erosive capacity manifested in bank and bed scour.
