    Torrential floods are hydrological natural hazards by nature of their occurrence, but with a high scale of severe damages to the facilities and infrastructure and a high number of casualties in human ... populated environment, they can become a natural disaster. In addition, they cause more or less significant environmental changes, such as geomorphological damages to river banks and river channels. In enhancing the existing capabilities of flash flood risk management for meso- and small-scale basins, building a hydrological model for a specific watershed is of great significance. In this paper, a hydrological model is created using the Shetran hydrological software for the upper part of the Toplica River basin located on the eastern slopes of Mount Kopaonik in Southern Serbia. The watershed model is based on extreme rainfall events and involves a large dataset of natural characteristics (relief, geological terrain, soil, vegetation and microclimate) and land use factor in the calculation of torrential flood occurrence. Shetran is used to enable the transformation of rainfall in the runoff with the aim of getting simulated flood hydrographs that correspond with the registered hydrographs as much as possible. Model-sensitive parameters are determined and subsequently calibrated and validated. The average coefficient of determination for the watershed model of the Toplica River/ profile Magovo when registered and modelled hourly discharges are compared reaches 0.87, showing a good precision so that it can be useful in torrential flood forecasting.
