黄河内蒙古什四份子河段冰凌演进数值模拟
Numerical Simulation of Ice Sheet Evolution in the Shisifenzi Section of the Yellow River in Inner Mongolia
摘要
Abstract
Influenced by external conditions such as climate and river channels,ice-run disasters in the Inner Mongolia section of the Yellow River are characterized by strong suddenness and destructiveness,which brings great pressure to ice prevention in the Yellow River.Especial-ly,the Shisifenzi bend in the Toudaoguai section of the Yellow River in Inner Mongolia is very easy to become the initial ice-run position ev-ery year due to the influence of multiple factors such as the shrinkage of the river channel,the increase of the ice volume from the upper rea-ches and the morphology of the river channel.In this paper,in view of the frequent occurrence of flooding disaster and the difficulty of risk prevention and control in the Shisifenzi section of the Yellow River in Inner Mongolia,based on the measured topography and water depth da-ta of the river channel and using the hydrodynamic module and particle tracking module of MIEK21,a coupled numerical model of ice-run was constructed,and a simulation analysis was carried out on the Shisifenzi River section of the Yellow River to study the trajectory of ice-run under the conditions of different incoming ice quantities and the densification of the ice.The result reveals that the ice movement law in Shisifenzi section of the Yellow River.关键词
