Floods and droughts on the lower Vistula
Main Article Content
Abstract
The study analyses floods and droughts on the lower Vistula based on the data (water levels and flow rates) recorded in stations of the Institute of Meteorology and Water Management – National Research Institute (IMGW-PIB) in Warsaw, Kępa Polska, Toruń and Tczew. It also includes the causes of flooding and drought in the lower Vistula with the hydrological characteristics from the years 1951–2010. The variability in maximum and minimum annual and monthly flow rates has been analysed for the aforementioned period as well. In addition, the authors have analysed changes in the shape of the flood wave after passing through the reservoir and cascade in Włocławek based on the hydrograph of May and June 2010. It has been found that the flood wave is flattened and extended. This phenomenon is favourable from the point of view of flood actions.
