Modelling of Impact Caused by Flood after Water Flow Optimization at Volga-Kama River Basin

In this paper two different water flood scenarios at Volga-Kama river in Russia are presented. First scenario is based on the existing water management approach that has been implemented in the period from 23 August 2013 until 22 August 2014. The second scenario is based on the original management approach aimed at mitigation of flood impact to the populated areas. The flood propagation has been modelled in HEC-RAS software, while post-processing and impact analysis were performed in QGIS 3.0. The results show that proposed original management approach allows to decrease the impact caused by inundation at Volga-Kama river basin by two times compared to the one implemented by the operator management approach. This result is achieved due to mitigation of the flood in highly populated areas and allowing additional water discharge among water management facilities in the areas with low population.
