The study in the Vistula basin in Poland examined the propagation process from meteorological to hydrological drought, focusing on the relationships between drought indices and identifying factors affecting drought variability induced by natural processes and human interaction. Results showed that the basin's upstream part is mainly influenced by the mining industry, while the middle and downstream parts are additionally affected by industry and agriculture.
The process of propagation from meteorological to hydrological drought is studied using the Vistula basin in Poland (193,960 km(2)) as a case study. The study aims to set a background for the analysis of processes influencing drought propagation in the basin, including the availability of data on hydro-meteorological factors, groundwater, and major human activities that might influence the water cycle in the region. A recent history of drought events in the basin is derived based on a statistical analysis of flow measured at nine gauging stations located along the river, starting from upstream downwards in the 1951-2018 period. The study is enhanced by the analysis of the temporal and spatial variability of a number of drought indices. As a result, the factors affecting temporal and spatial variability of drought-with particular emphasis on the interaction between the variability induced by natural processes and human interaction-are identified. The drought dynamics is studied by analysis of the relationships between meteorological and hydrological drought indices. The results indicate that the Vistula River basin has been influenced in its upstream part mainly by the mining industry, and the middle and downstream parts are additionally affected by industry and agriculture.
