Abstract	Ljudi svojim aktivnostima neprestano utječu na životne uvjete zajednica bentičkih beskralježnjaka, pogotovo hidroelektranama koje u pravilu izazivaju veliki stres. Nagle promjene protoka vode mogu utjecati na brzinu strujanja i dubinu vode, što mijenja pritisak protoka vode na korito tekućice (shear stres). Uzajamni utjecaj karakteristika protoka vode na beskralježnjake pri pojavi bujičnih valova još uvijek nije u potpunosti shvaćen. Unatoč tome, postoji neosporna veza između pojava bujičnih valova i drifta beskralježnjaka. Hrapavost podloge je jedan od parametara koji utječu na „shear stres“, te time i na bentičke beskralježnjake. Predmet i glavni interes ovog rada bio je istražiti utjecaj hrapavosti površine na drift makrozoobentosa pri pojavi bujičnih valova. Dobiveni rezultati nisu pokazali značajan utjecaj hrapavost podloge na pojačani drift pri pojavi bujičnih valova. Statistički značajan utjecaj hrapavosti podloge na pojačan drift makrozoobentosa primijećen je samo kod nekih svojti kao što su Chironomidae, Elmidae, Ephemerellidae i Nemouridae pri pojavi bujičnih valova, dok kod Chironomidae i Ephemerellidae statistički značajan utjecaj hrapavosti podloge na pojačan drift zabilježen je pri bazičnom protoku vode. Naši rezultati su potvrdili vezu između pojave bujičnih valova i pojačanog drifta beskralježnjaka sa statističkim značajnom razlikom u stopi drifta pri pojačanom i bazičnom protoku vode.
Abstract (english)	Human activity constantly influences the living conditions of benthic communities, where hydropower plants act as big stressors. Sudden discharge of water into a stream can change many flow characteristics like water velocity and depth, which changes shear stress. Mutual influence of those characteristics on macroinvertebrates during hydropeaking is still not fully understood. However, the link between hydropeaking and drift of macroinvertebrates is undisputable, although the final effect depends on taxa involved. Sediment roughness is also one of the characteristics that influence shear stress, and consequently affect benthic invertebrates. Therefore, this thesis deals with the effect of substrate roughness on drift of different macroinvertebrate taxa in hydropeaking conditions. Based on given results, substrate roughness has not proved to be a major influence source of increased drift in hydropeaking events. Significant influence of sediment roughness on increased drift has only been observed in some taxa like Chironomidae, Elmidae, Ephemerellidae and Nemouridae in hydropeaking events, whereas in Chironomidae and Ephemerellidae in base flow. However, our results confirmed the connection between hydropeaking and increased drift with significant differences in drift rates in hydropeaking and base flow conditions.
