Geopolitical conflicts, for which the last century is so notorious, have obscured the lives and achievements of many talented scientists. Kirill Vladimirovich Grishanin, Professor of Fluvial Hydraulics and Channel Processes of the St. Petersburg State University of Waterways of Russia, lived a life that spanned almost the whole of the twentieth century, and during which he pioneered and advanced the research on the dynamics of alluvial channels. Although his theoretical studies have provided the fundamentals for the Russian School of Fluvial Hydraulics, with five generations of engineers and scientists having learned from his canonical textbooks, the immense legacy he left behind is still shadowed by ruins of the iron curtain. This work is dedicated to the centennial jubilee of Grishanin's birthday, provides a brief overview of his scientific discoveries and biographical details, and aims to secure a special place for this outstanding Russian researcher in the European history of hydraulics. © 2011 International Association for Hydro-Environment Engineering and Research.

At each of five fixed locations along the ground tracks of JASON-1 and ENVISAT, a repeat-track analysis of 1-Hz sea surface height (SSH) data has been conducted to assess the performance of waveform retrackers over Lake Baikal in Siberia, Russia. This simple analysis of time series at each point location is needed to minimize the effect of the range correction artifacts in current Geophysical Data Record (GDR) data products of radar altimeters in in-land areas. Using the retracked data available in the GDRs as the baseline, two retrackers are evaluated in terms of the number of valid data points produced and the degree of agreement with in-situ data of water level record. The threshold retrackers that are based on the amplitude of the robust OCOG algorithm (Offset Center of Gravity) are found to perform the best in Lake Baikal.
