| Abstract: | According to ice regine in cold zone,This paper deals with Numerical model of ice regime forecast.This model is composed of two part:a)one dimensional unsteady flow model,b)one dimensional thermal model.The model can simulate flow characteristic;Water temperature variation along the channel;frazil ice concentration distribution,ice cover formation;undercover ice transport,depostion;thermal growth and decay of ice cover.It can provide the criterion to safeguarcl normal operation of conveyance channel. |
