Runoff regime in the Croatian part of Bregana catchment area

Bregana je dijelom toka granični vodotok između Republike Hrvatske i Republike Slovenije. Premda se u radu klimatološki i hidrološki podaci odnose na hrvatski dio porječja, reprezentativni su i za, površinom znatno manji, slovenski dio. Rad se sastoji od prikaza hidrogeoloških i hidrometeoroloških uvjeta otjecanja, geomorfoloških obilježja, zemljišnog pokrova, antropogenih utjecaja i hidroloških obilježja. Analizirani su srednji godišnji (maksimalni, prosječni, minimalni) i sezonski protoci te protočni režimi na tri aktivne hidrološke postaje u porječju. Usporedbom podataka razdoblja 1981. – 2000. i 2001. – 2020. pokazale su se određene promjene u protocima, koje su potom uspoređene s promjenama u padalinskom režimu, pojavom snijega i temperature zraka.Bregana River is in part a border watercourse between the Republic of Croatia and the Republic of Slovenia. Although climate and hydrological data refer to the Croatian part of the basin, they are also representative for the Slovenian part, significantly smaller in it's area. An overview of hydrogeological and hydrometeorological conditions of runoff, geomorphological features, land cover, anthropogenic influences and hydrological features are presented. Mean annual (maximum, average, minimum) and seasonal discharges and discharge regimes were analyzed on the three active hydrological stations in the basin. Comparing data from the period 1981-2000 and 2001-2020 certain changes were recognised, which were then compared with changes in the precipitation regimes, snow appearance and air temperature
