Experts believe that the dams near Khabarovsk will be able to stop the changes in the Amur channel
From 9 to 16 June, Amur is undergoing a comprehensive expedition of the Ministry of Emergency Situations to assess riverbed processes after a flood. On Friday, march participants arrived in Khabarovsk.
According to the deputy director of the Institute for Water and Environmental Problems of the Far Eastern Branch of the Russian Academy of Sciences, Alexei Makhinov, the destruction of the dams will cause the Amur to leave the city, which will disrupt shipping and the ecology of Khabarovsk.
He argues that channel processes on the river are ongoing - the banks are eroded, new sandbanks appear, but the flood has accelerated the changes. The process of the river leaving the city, but of lesser intensity, was noted earlier. To prevent it, half dams were built on the Pemzenskaya and Beshennaya channels in the Khabarovsk region. After the flood, some parts of the dams collapsed, the current intensified and the process of erosion of the banks accelerated. Therefore, it is urgent to start strengthening these dams and the banks between the channels.
"They cannot be destroyed, huge funds were spent on the construction of half-dams, and if they are destroyed, this will entail Amur's withdrawal from the city, shipping, ecology, and life support of the city will be disrupted, because Khabarovsk was built taking into account the current channel," Makhinov said.
He also noted that dams may not withstand repeated large-scale flooding, the likelihood of which exists in the coming 10 years.
