【摘要】 本文根据寒冷地区输水渠道的冰情建立了冰情预报数学模型，这个模型由一维非恒定流水力学模型和一维热力学模型组成．可以预测渠道的水流特性、水温沿程分布．冰花流量、冰盖形成、冰盖下冰花的传输和堆积、冰盖的热力学增厚和融化，为保证渠道正常运行提供依据．更多还原

【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.更多还原
