V članku avtorici predstavljata izsledke štiridesetletnih hidroloških opazovanj poplav v poreč ju reke Ochotnice (1972–2011). Reka Ochotnica teče v pogorju Gorce v poljskem delu Zahodnih Karpatov. Avtorici sta značilnosti poplav v strugi reke analizirali na podlagi limnigrafskih podatkov o vodni gladini, izmerjenih na merilni postaji v kraju Tilmanova, in podatkov o količini padavin, ki sta jih pridobili od Poljskega meteorološkega inštituta in vodomerne postaje v kraju Ochotnica Górna. Na podlagi tega sta določili vrste poplav. Na reki Ochotnica prevladujejo normalne poplave z zimskim pretokom 3,80–11,9m³/s in poletnim pretokom 4,74–16,40m³/s. Prevladujoči proces v zadnjem času je vrezovanje, in sicer s povprečno hitrostjo 3,2cm/leto. Podobni rezultati so bili ugotovljeni tudi pri drugih evropskih gorskih rekah.
