River basin digital twin: A tool for modelling adaptation measures for water retention in a landscape affected by climate change
River basin digital twin technology is an advanced tool for assessing the effects of complex adaptation measures on the water balance in the context of ongoing climate change. The integrated, fully distributed, physically based MIKE SHE modelling system forms the basis of the digital twin developed for detailed simulation of the hydrological cycle. Using the Dyje River basin and the pilot upper Svratka catchment as case studies, specific measures to promote natural infiltration and enhance baseflow were tested, designed and quantified. The effects of climate change were assessed using an ensemble of 26 independent climate scenarios based on global climate models (CMIP6) for a 30-year period centred on 2050, compared with the historical reference period 1981–2010.
HYMOD-KZ database and deficit areas
This article describes the HYMOD-KZ database, available at https://shiny.vuv.cz/HYMOD-KZ/. The database provides detailed results of hydrological modelling and hydrological balance analysis of catchments (water bodies) for current and future climate conditions; it also includes updated deficit areas, the description of which is part of this article. This tool can serve as a foundation for water management ex-perts, academia, and the broader professional community as it provides outputs at the spatial resolution of water bodies. The graphical rep-resentation of results facilitates understanding of complex hydrological phenomena and supports decision-making in water management planning.
