Abstract
Kruženje vode u prirodi je glavna stavka hidrološkog ciklusa koja omogućuje život na Zemlji. Otjecanje je jedan od glavnih parametara kruženja vode u prirodi koji se odnosi na kretanje vode s površine tla. Tlo koje je zahvaćeno velikim obimom vode može izgubiti ili smanjiti svoju plodnost koje je ključna značajka za prehranjivanje svoje okoline. Ovaj rad ima cilj uspostaviti numerički model otjecanja podsliva rijeke Orljave. Numerički model se oslanja na MDF metodu koja težinski usmjerava tok vode niz topografiju kroz niz iteracija u ovisnosti o nagibima za svaki pojedini čvor domene. Topografski podaci su preuzeti iz Copernicus baze podataka u obliku digitalnog modela visina u 25 m rezoluciji. Algoritam numeričkog modela je implementiran unutar sučelja programskog paketa QGIS. S obzirom da numerički model kao rezultat daje dubinu vode, koristili smo Manningovu jednadžbu kako bi se dubina vode pretvorila u protok na lokaciji hidrološke postaje Požega. U svrhu kalibracije modela, koristili smo mjerene protoke trajanja 1% mjerne na stanici Požega. Nakon provedene kalibracije modela i uspostave tražene dubine vodotoka na lokaciji hidrološke stanice Požega, numerički model daje dodatnu vrijednost u obliku prostorne raspodjele dubina vode po cijelom slivnom području.
Abstract (english)
The circulation of water in nature is the main element of the hydrological cycle that enables life on Earth. Runoff is one of the main factors of the water cycle in nature, which refers to the movement of water on the earth’s surface. The aim of this work is to establish a numerical model of the runoff of the Orljava river sub-basin. The numerical model relies on the MDF method, which weight-directs the discharge of water down the topography through a series of iterations depending on the slopes for each individual node of the domain. The topographic data were taken from the Copernicus database in the form of a digital elevation model with a resolution of 25 m. The numerical model algorithm is implemented in QGIS. Given that the numerical model gives the water depth as a result, we used the Manning equation to convert the water depth into discharge at the Požega hydrological station location. For the purpose of calibrating the model, we used measured value of the annual exceedance probability of 1%. After the calibration of the model, the numerical model provides additional value in the form of the spatial distribution of water depths throughout the catchment area.
