“…Changes in river runoff are directly related to changes in regional precipitation. The climate trends in the HARB are generally consistent with global trends, with a significant upward trend in temperature [60]. Meteorological observations in Khabarovsk show an increased frequency and intensity of flooding in the HARB and the frequency of extreme meteorological events [61].…”

The Heilong-Amur river basin (HARB) is the largest transboundary river in Asia and is primarily located in its cold region. With global warming and geopolitical cooperation strengthening between Russia and China, the hydrology change and water security risks are receiving increasing attention. This study utilized the linear regression, Mann–Kendall, and cumulative anomaly methods to analyze changes observed in the upper HARB’s streamflow and water levels over 30 years. The collation of outcomes derived from the methods mentioned above, the indicators of the hydrological alterations process, and the range of variability approach method (IHA–RVA), coupled with results gleaned from the double cumulative curve method, facilitate a thorough evaluation of the perturbations in hydrologic indicators, as well as the impacts of anthropogenic activities. The results showed that the overall hydrological regimes of both streamflow and water levels at the Luoguhe (LGH), the Shangmachang (SMC), and the Kalunshan (KLS) displayed a mild decrease from 1988 to 2017. The streamflow decreased by 58%, 42%, and 38%, and water levels decreased by 48%, 53%, and 59%, respectively, at each station after the mutations. LGH station recorded the highest decrease rate in streamflow at 8.28 × 108 m3/a, whereas the steepest rate of decline in water levels was observed at KLS station at 0.05 m/a. Despite the decreasing trend in the high pulse count of streamflow across the three stations, a slight increase in the high pulse duration of streamflow was noted at SMC and KLS. Precipitation changes were the primary driving force behind runoff alterations, contributing 62%, 84%, and 90% at LGH, SMC, and KLS, respectively, significantly higher than the contribution from anthropogenic activities (38%, 16%, and 10%, respectively). These findings also underscore the suitability of the methodologies employed in this study for application in cold regions.

The article presents the results of a study of floods in the southern regions of the Russian Far East. The analysis is based on the search for options for flood prevention, as well as better management of the consequences of floods to improve the quality of life of the population. The data on damage from floods in the period from 2013 to 2023 in certain Far Eastern regions are analyzed. On the example of the 2021 flood, it is shown that protective measures in the Amur Region after the catastrophic flood of 2013 helped reduce damage. However, there is still a high probability of recurrence of floods. Floods lead to the loss of personal property of the population, damage to transport infrastructure, agriculture in the regions, which reduces the quality of life of the population in the Far Eastern regions. Based on open damage data for 2021, it is shown that higher flood damage per capita is observed in regions with lower population density. The natural and social aspects of floods are reflected in their causes and consequences. It is shown that the anthropogenic causes of floods are largely associated with the expansion of economic activity. Despite the wide range and volume of financial support for the regions, for the population, the total amount of compensation in case of damage cannot compensate for all their financial losses. One of the options for reducing damage is considered the possibility of developing a program for the resettlement of the population from areas located in the flood zone.
