Flow dynamics in alluvial channels: the legacy of Kirill V. Grishanin

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.
