Record #123879:

Kinematic model of river ice motion during dynamic breakup. Paper presented at the 9th Northern Res. Basin Symposium/Workshop (Whitehorse/Dawson/Inuvik, Canada - August 1992) / Michael G. Ferrick, Patricia B. Weyrick, D.F. Nelson.

Title: Kinematic model of river ice motion during dynamic breakup. Paper presented at the 9th Northern Res. Basin Symposium/Workshop (Whitehorse/Dawson/Inuvik, Canada - August 1992) / Michael G. Ferrick, Patricia B. Weyrick, D.F. Nelson.
Author(s): Ferrick, Michael G.
Weyrick, Patricia B.
Nelson, D. F.
Date: 1993.
In: Nordic Hydrology. (1993.), Vol. 24(2-3) (1993)
Abstract: Formulates kinematic model: ice continuity equations are applied relating speeds of breaking front, convergence front, stoppage front, and release front with ice discharge and volume per unit area (unit volume) on either side of each front. Ice velocity was measured with time during breakup at paired sites bounding reach of Connecticut River. Ice and front motion were simulated using model with assumption that accumulation thickness and porosity are uniform and that changes in ice conditions and motion occur only at front. Contrary to basic assumption of static jam formation, accumulation developed while ice was moving and jam formation represented merely arrest of motion.
