Modelling River Ice Freeze-up on the Red River near Netley Cut

摘要

This paper presents the preliminary results of a river ice dynamics study conducted on the Red River near Netley Cut in Manitoba, Canada. CRISSP2D, a two-dimensional finite element model typically used to study the characteristics of ice formation, movement, and break up, was used to simulate the hydrodynamics and ice dynamics in the study area. A field program was undertaken to obtain water depth, velocity and temperature measurements for seventeen locations throughout the study area over a five month period. The data collected from this program was used in the hydrodynamic calibration and verification of the model. Results of these simulations indicate that the model is able to accurately simulate the measured data. The calibrated model was used as an input to the dynamic ice module of CRISSP2D and preliminary ice formation simulations were completed. Preliminary model calibration was completed which examined the effects of various heat loss coefficients on the ice thickening rate. Further calibration and verification of this model is required to adequately simulate ice processes in the study area.
