20.500.12556/RUL-114100 Rainfall-runoff modeling of the nested non-homogeneous Sava River sub-catchments in Slovenia Rainfall-runoff modeling is nowadays applied for water resources management, water system design, real-time forecasting, flood design and can be carried out by using different types of hydrological models. In this study, we focused on lumped conceptual hydrological models and their performance in diverse sub-catchments of the Sava River in Slovenia, related to their size and non-homogeneity. We evaluated the difference between modeled and measured discharges of selected discharge gauging stations, using different model performance criteria that are usually applied in hydrology, connecting the results to geospatial analysis of geological and hydrogeological characteristics, land use, runoff potential, proportion of agglomeration and various meteorological variables. Better model performance was obtained for catchments with a higher runoff potential and with less variations in meteorological variables. Regarding the number of used parameters, the results indicated that the tested Genie Rural 6-parameter Journalier (GR6J) model with 6 parameters performed better than the Genie Rural 4-parameter Journalier (GR4J) model with 4 parameters, especially in the case of larger sub-catchments. These results illustrate the comprehensive nature of lumped models. Thus, they yield good performance in case of the catchments with indistinguishable characteristics. hydrological modeling rainfall-runoff lumped conceptual model model efficiency criteria non-homogeneous catchment Sava River hidrološko modeliranje padavine odtok enoviti konceptualni modeli ustreznost modelov nehomogena porečja Sava true false true Angleški jezik Slovenski jezik Članek v reviji 2020-02-14 14:40:44 2020-02-14 14:49:43 2022-08-26 03:49:06 0000-00-00 00:00:00 2020 0 0 13 str. iss. 1, art. 128 Vol. 12 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 556.5(497.4) 2073-4441 10.3390/w12010128 9010273 36731653 RAZ_Lavtar_Katarina_2020.pdf RAZ_Lavtar_Katarina_2020.pdf 1 B10EA4CE37225D6070217939BC67D01F 8d2eb5cad4b149520d18ba877e9fad6bf5e5891eaf649515ff2ce58f1ecf1c79 23d989a6-4b63-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151274 https://www.mdpi.com/2073-4441/12/1/128 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=126229 Fakulteta za gradbeništvo in geodezijo 0 0 0
