The article presents the results of a study on spatial distribution of water runoff in the Pripyat basin rivers in Ukraine. The authors analysed long-term observational data from 28 hydrological stations in the territory of Ukraine and 30 stations outside its borders. The data obtained from these stations comprised a period from the beginning of their operation up to and including 2017. The authors employed GIS technology to automate the process, and made use of different types of interpolation to ensure more accurate calculations. The study resulted in the creation of an updated modern map of water runoff for the territory of the Pripyat basin rivers in Ukraine, with isolines every 0.2 l·s-1·km-2. This can be used to determine the values of specific water runoff rates for rivers not subject to constant observations, in particular with regard to rivers featuring small water catchment for more convenient and faster use.
