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．
In this paper, a mathematical model of ice condition prediction is established based on the ice conditions in the water supply channels in cold regions. This model consists of a one-dimensional unsteady flow hydraulic model and a one-dimensional thermodynamic model. Can predict the flow characteristics of the channel, along the distribution of water temperature. Ice flow, the formation of ice sheets, the ice sheet under the transmission and accumulation of ice, thermodynamic thickening and melting ice sheet, in order to ensure the normal operation of the channel to provide the basis.
