Forming Conditions and Probable Values of Maximum Water Levels of the Lena River near Yakutsk

A. V. Rozhdestvenskii, V. A. Buzin, and T. L. Shalashina

The genesis of the formation of maximum water levels of the Lena River near Yakutsk is considered. Recovery techniques of series of hydrological characteristics is briefly stated. Observational data on maximum water levels are reduced to the long-term period, an estimation of their homogeneity and stationarity is carried out. The recomputation of maximum water levels of 1% probability taking account of extreme historical levels is executed. As a result, the mark of calculated 1% maximum water level (97.34 m, Baltic System) is obtained, which is 0.98 m higher than the one given in hydrological handbooks [1, 6].
