Impact of Floods on the Channel Regime of the Nalchik River (Kabardino-Balkar Republic)

Abstract

The purpose of the work is to study the impact of floods on the channel regime of the Nalchik River in order to develop recommendations for the protection of the riverbank and infrastructure of the Nalchik urban district from flood damage. Materials and methods. This study is based on the analysis of data obtained during field surveys of the coastal territory of the Nalchik River (May-June 2023 and June-July 2024), using archival materials, hydrological characteristics of the river and its main tributaries. Results and discussion. Having analysed archival materials and results of field surveys of the Nalchik River channel after the floods of 2023-2024, the hazardous areas most exposed to the destructive impact of flood waters have been identified. The maximum values of water discharge of 1 % capacity at the most dangerous sections of the Nalchik River bed were determined. Conclusion. Recommendations on integrated protection of the Nalchik River shoreline on the territory of the Nalchik urban district to minimise flood damage to infrastructure and safe use of recreational areas are proposed.
