Break-up Flood Risk and Climatic Warming in Yakutsk (Russia)
International audience The Lena River is the major axis that structures a part of central and oriental Siberia. Real motorway in winter and seaway in summer, it is the only way that allows the goods transportation in quantity. More than 40 % of the Saka Republic (Yakoutia) inhabitants live along the...

International audience The Lena River is the major axis that structures a part of central and oriental Siberia. Real motorway in winter and seaway in summer, it is the only way that allows the goods transportation in quantity. More than 40 % of the Saka Republic (Yakoutia) inhabitants live along the Léna. It was the main antropisation axis and is the main urbanization axis at the present day. Its nival regime is characterized by a great excessiveness due to the cold continental climate and opposes low winter flows to enormous spring flows during break-up. Climatic warming during the end of XX th century causes increase of flow, thickening of permafrost active band and thinning down of superficial ice layer in winter. In spring, melting is earlier in May and daily discharges are lower in June. There a few change in summer but September and October discharges decrease.
