Abstract
Land use changes are important in water circulation. Already at the stage of water supply to basin
precipitation it’s modified into effective precipitation and then filters into the substrate or runs off the surface
of the area. Identifying the significance of these changes is key in setting the limits for urbanization in terms
of water management and flood protection. The most commonly used method for calculating the precipitation
effect that causes outflow is the SCS method. The underlying assumption of this method is the dependence of
effective precipitation on the type of land cover, soil and soil moisture. This article presents the application
of this method in the context of the study of surface runoff in an urbanized area, where changes in land use
during the last century have influenced the runoff.
