Mapping the Mean Annual River Runoff in the Ukrainian Carpathian Region
Keywords:rivers of the Ukrainian Carpathian region, analytical functions of GIS, spatial distribution, mean annual river runoff (annual normal flow), specific discharge river basin, coefficient of variation.
The paper presents the spatial distribution of the mean annual river runoff in the Ukrainian Carpathians in the form of a map. The methodological approaches concerning the river runoff mapping and the technological stages of map creation by applying the geographic information system (GIS) analytical functions are considered. The accuracy assessment of the calculation of the mean annual river runoff water based on the data from the hydrometric stations for the whole observation period was performed. The mapping reliability of the mean annual runoff and their territorial variability over the main basins in the Ukrainian Carpathians are analysed.
