Impact of Large Floods on Water Resources and Infrastructure of Urban Areas in the Amur River Region

Abstract

This article considers the impact of rainfall floods of the Amur river on the distribution of suspended sediments and the content of heavy metals in the watercourse. It presents measurement data of these parameters for equal flood rise and fall flows. The authors found out that factors like a high proportion of watercourse width to its depth, the presence of large tributaries, and the branching of the river course have the strongest impact on the heterogeneity of the distribution of terrigenous and chemical substances across the length and width of the river. They also identified the key impacts of large floods that transform the river course and have negative effects on the reliability and conditions of waterworks within urban territories.
