For short-term forecast of ice-jam levels, a model of river ice jamming, based on numerical solution of Sen-Venan equations using Militeev’s implicit scheme was developed. The model was enlarged with a simple model of ice-jam length increase. Computation of an observed ice jam was used for model verification. Computing velocity vectors on this model allows estimation of dynamic load on facilities within the river valley during flooding. Results of the research revealed the origin of extremely high ice-jam stages. High roughness factor of ice lower surface causes high stage rise upstream the jam.
