Abstract

Peculiarities of extreme runoffs formation, changes dynamics and recurrence of rivers in the Arpa River basin are discussed. The main peculiarity of formation of extreme runoffs is that both natural and anthropogenic factors have almost identical influence. In dynamics of absolutely maximal and absolutely minimal runoffs, generally reduction tendency is observed. If in case of maximal runoffs the risk degree has sharply decreased, then in case of minimal runoffs it has increased that makes river ecosystems most vulnerable.
