“…The inflow volume in 2012 was 200−1000% of the mean annual flow and many rivers were covered by ice in a previously unobserved fullbank flow. The frequency of this event was estimated as once in approximately 500 to 1000 yr (Gartsman et al, 2014), likely not as rare as the Amur River 2013 event. Hydrological extremes are nonlinear responses to climate fluctuation and may represent initial changes in the hydrological regime of the whole region.…”

-The freshwater ecosystems of the Southern Region Of the Russian Far East (SRORFE) are subject to the influence of environmental extremes (especially heavy floods and droughts). Within forested areas, extreme floods do not destroy the ecosystems of rivers and floodplain lakes; in contrast, periodic medium and small floods alternating with low-flow periods are beneficial to these ecosystems. In the 21st century, the natural flood cycles will change, likely increasing the peaks of floods but decreasing the probability of rain during the dry season. Extreme floods can lead to the rapid depletion of river phytoplankton and zoobenthos and can cause long-term water hyper-eutrophication. Droughts will increase the probability of forest fires. The loss of forest cover due to logging and fires will intensify the unsteadiness of hydrological regimes of water bodies. In the SRORFE global environmental change, accompanied by increasing anthropogenic pressures and a lack of protective measures will cause a significant loss of biodiversity among freshwater biota. Meanwhile, forest preservation will ease the negative effects on the biodiversity and productivity of freshwater ecosystems in the SRORFE.Key-words: freshwater ecosystems / global warming environmental extremes / eutrophication / forest fires Résumé -Les écosystèmes d'eau douce de la région sud de l'Extrême-Orient russe subissent des changements environnementaux extrêmes. Les écosystèmes d'eau douce de la région du sud de l'Extrême-Orient russe (SRORFE) sont soumis à l'influence des conditions environnementales extrêmes (en particulier de fortes inondations et des séche-resses). Dans les zones boisées, les inondations ne détruisent pas les écosystèmes des rivières et des lacs des plaines inondables ; au contraire, de petites à moyennes inondations périodiques alternant avec des périodes de faible débit sont bénéfiques pour ces écosystèmes. Au 21 e siècle, les cycles naturels d'inondation vont changer, avec probablement augmentation des pics d'inondations, mais diminution de la probabilité de pluie pendant la saison sèche. Les crues extrêmes peuvent conduire à l'épuisement rapide du phytoplancton et du zoobenthos de la rivière et peuvent causer à long terme l'hyper-eutrophisation de l'eau. Les sécheresses augmenteront la probabilité d'incendies de forêt. La perte de la couverture forestière en raison de l'exploitation forestière et des incendies intensifiera le déséquilibre des régimes hydrologiques des masses d'eau. Dans le SRORFE, les changements environnementaux mondiaux, accompagnés d'une augmentation des pressions anthropiques et de l'absence de mesures de protection entraînent une perte importante de la biodiversité dans les communautés d'eau douce. En même temps, la préservation des forêts va atténuer les effets négatifs sur la biodiversité et la productivité des écosystèmes d'eau douce dans le SRORFE.Mots-clés : écosystèmes d'eau douce / réchauffement climatique / extrêmes environnementaux / eutrophisation / incendies de forêt

In 2013, a catastrophic flood occurred on the Amur River, caused by heavy rainfall throughout almost the entire basin. The floodplains of Blagoveshchensk, Khabarovsk, and Komsomolsk-on-Amur were flooded. Similar hydrological phenomena on the Amur occurred earlier (1954, 1972, and 1984), but they did not lead to catastrophic flooding. In the proposed manuscript, the authors investigated three issues: the causes of the 2013 flood, advanced hydrological forecast, and measures to prevent catastrophic flooding. For research, a hydrodynamic model of the Amur River section from Blagoveshchensk to the mouth was developed. Based on the analysis of model calculations, it was shown that some flood problems arose due to the construction of hydraulic structures in recent years (protective dams, bridges, and embankments) and a medium-term forecast scheme proposed.

“…played a role in strengthening the flood (compare with Gartsman et al, 2014;Danilov-Danilyan and Gelfan, 2014) and may be associated with changes in the hydrological regime of the region, although there is no complete clarity in this question.…”

We studied the interaction of surface water and groundwater at the origin and development of catastrophic floods. Intense atmospheric precipitation is traditionally considered as the main factor of their occurrence. At the same time, we discuss the role of seismic processes as a factor that potentially influences on the occurrence of catastrophic floods. We made an analysis of the observed natural events, which confirm the impact of seismic activity on the state of groundwater and, therefore, on surface water. We also suggested an original approach to forecast the catastrophic floods on the basis of the analysis of seismic activity in respect of specific hydrological events that took place in 2013-2014.
