The role of hydrological models in water management is significant. One of their important applications is the development and management of water resources, including water quality and sediment transport. Semi-distributed hydrological models, such as HBV-light, provide the possibility of dividing the catchment into sub-catchments and zones according to height and type of land cover. GIS tools provide significant support to prepare input for these models. The paper presents the methodology for preparing input data, using the QGIS tool, for the HBV-light hydrological model, which is used for continuous hydrological simulations. This model transforms precipitation from the catchment into runoff. Three alternative methods are described and compared within the methodology, based on the example of the Veternica river catchment. Uloga hidroloških modela u vodoprivredi je značajna. Jedna od njihovih važnih primena je u razvoju i upravljanju vodnim resursima, uključujući i kvalitet vode i pronos nanosa. Semi-distribuirani hidrološki modeli, kao što je HBV-light, pružaju mogućnost podele sliva reka na podslivove i na zone prema visinama i prema vrsti zemljišnog prekrivača. Da bi se pripremili ulazni podaci za ove modele GIS alati pružaju značajnu podršku. U radu je prikazana metodologija pripreme ulaznih podataka, korišćenjem alata QGIS, za HBV-light hidrološki model, koji služi za kontinualne hidrološke simulacije. Ovaj model transformiše padavine sa sliva u oticaj. U okviru metodologije, na primeru sliva reke Veternice, opisane su i upoređene tri alternativne metode.
