Abstract: Using long-term observations at four gauging stations along the Inner Mongolia Reach of the Yellow River in China, this paper explores both the ice regimen in general and the specific effects of the ice on the hydraulics of this river reach. The hydraulics of the reach and water levels are compared and contrasted for four different conditions: under open channel flow, during the ice flowing period, during the ice covered period, and during break-up. Associated rating curves, which are well behaved under open channel situations, are sometimes poorly defined and extremely variable under ice conditions. The results show that the water level is usually insensitive to flowing ice prior to freezeup. However, significant, but hardly surprising, variations are observed during icecovered conditions. The rating curves for both ice covered condition and river breakup period are developed and some related hydraulic issues are explored.
