Analysis of Revitalization Measures in Vortovský Stream Basin

The aim of this research was to evaluate the impact of revitalization measures implemented in the catchments of the Vortovský Stream and the Valčice Stream, located within the protected landscape area of the Žďárské vrchy in the Pardubice Region, Czech Republic. The assessment was conducted using rainfall–runoff models HEC-HMS 4.13(The Hydrologic Engineering Center’s-Hydrologic Modeling System) and MIKE SHE version 2020 (MIKE System Hydrological European), and hydraulic models HEC-RAS 6.6 and MIKE 11 version 2020. The study focused on comparing the effects of revitalization on flow velocity in the Valčice Stream with its original state, evaluating the ability of the reconstructed ponds Malý Černý and Velký Černý to transform flood waves, and assessing the overall effectiveness of the revitalized areas in water retention within the landscape. The results demonstrate that the reconstruction of the ponds on the Valčice Stream significantly contributed to the safe transformation of flood flows, and that the revitalization of part of the stream resulted in a reduction in flow velocity in the channel. Furthermore, the revitalization measures in the Vortovský Stream catchment were found to have a positive effect on enhancing water retention in the area.
