摘要
Abstract
The water conveyance line of South-to-North Water Diversion, from south to north, goes from the warm zone into the semi cold area. Under the influence of temperature changes, ice may occur along the line at different degrees, which will af-fect the operational safety and efficiency of water diversion channel. Based on the Saint-Venant equation that is used to describe the unsteady flow in an open channel, the water resistances of frozen and ice sheet sections are analyzed. Furthermore, the modi-fied Saint-Venant equation for the water condition in ice period is obtained, which can provide a theoretical basis for the channel hydraulics simulation in ice period.关键词
