Abstract

This article examines different annual trends in the climate and hydrological changes in the Slovenian part of the Drava Basin (Sln. Podravje) between 1961 and 2018. Climate change is primarily reflected in the rising average annual temperatures and a significantly shorter duration of snow cover. In terms of hydrological changes, a decrease in the average annual minimum and mean annual discharge can be observed, whereas the average maximum and absolute discharge is increasing in places. In addition to the water volume, changes can also be observed in the rivers’ discharge regimes, which may indicate a smaller probability of spring floods, but conversely a higher probability of fall floods.<br />V prispevku obravnavamo različne letne trende podnebnih in hidroloških spremenljivk na območju slovenskega dela porečja Drave med letoma 1961 in 2018. Prve se odražajo predvsem v rasti povprečne letne temperature in močno skrajšanem trajanju snežne odeje. Pri drugih pa je opazno padanje povprečnih minimalnih in srednjih letnih pretokov, povprečni maksimalni in absolutni maksimalni pretoki pa ponekod naraščajo. Poleg vodnih količin se pri rekah spreminjajo tudi pretočni režimi, ki po eni strani lahko kažejo manjšo možnost spomladanskih poplav, po drugi strani pa večjo možnost jesenskih poplav.
