Abstract: The paper contains the results of the hydrological generalization of the features of river ice regime of the Arctic zone of Western Siberia. The rivers under study (Nadym, Pur, Taz, the lower Ob and others) flow in swamped lowland in the area of permafrost, which defines the peculiarities of their hydrological conditions. The author studies the ice regime of navigation and ice crossing on these rivers. Special attention is given to the characteristics of the level regime in the period of ice phenomena, which helps define the danger of ice-related floods. The research is based on the data of 40 stage gauges from the start of measurements to 2014. The author demonstrates the patterns of special distribution of the main characteristics of the ice regime, determined by the dependence of average values on the geographic latitude of the studied areas. The author considers regional peculiarities of the conditions of ice level growth during the ice formation period and defines the floodable inhabited areas.
