Abstract: Long distance water diversion project is an important engineering measure to solve the allocation of water resources. In the cold area, the winter freezing of water conveyance project affects the normal operation of the channel. This paper studies the space-time evolution of ice in winter long distance water conveyance project based on the prototype observation data of the winter ice. In the field of time, the different ice conditions of border ice, moving ice, ice cover, ice thickness and ice melting are studied. The effect of temperature, water temperature and water flow on the time of ice age is considered. In the field of space, according to the different channels of winter ice conditions, the ice range of channel of the long distance water diversion project is analyzed. The main frozen channel and buildings are determined. It provides technical support for winter operation of long distance water conveyance project.
