Lešće hydroelectric power plant and its impact on the hydrological and geomorphological characteristics of the Dobra River

Hidroelektrana Lešće prva je hidroelektrana izgrađena u samostalnoj Hrvatskoj državi, a od samog početka realizacije ovog projekta postoje rasprave o pozitivnim i negativnim utjecajima ove hidroelektrane na rijeku Dobru te turizam i gospodarstvo okolnog prostora. To je bio poticaj za detaljniju analizu utjecaja koje hidroelektrana Lešće ima na rijeku Dobru. U radu je provedena analiza hidroloških podataka te geomorfoloških obilježja rijeke Dobre te su na temelju dobivenih rezultata doneseni određeni zaključci. Analize su pokazale kako hidroelektrana tijekom svog rada ostvaruje utjecaj na hidrološka obilježja rijeke Dobre što se primarno manifestira kroz pojave velikih vodnih valova. Analize su također pokazale kako izmijenjena hidrološka obilježja utječu na geomorfološka obilježja rijeke Dobre kroz pojačano širenje korita rijeke.Lešće hydroelectric power plant is the first hydroelectric power plant constructed in the independent Croatian state and from the very beginning of this project there are discussions about the positive and negative impacts of this hydroelectric power plant on the Dobra River and tourism and economy of the surrounding area. This was the incentive for a more detailed analysis of the impacts that the Lešće hydroelectric power plant has on the Dobra River. The paper analyzes the hydrological data and geomorphological characteristics of the Dobra River and based on the obtained results, certain conclusions are reached. Analyzes have shown that the hydropower plant has an impact on the hydrological characteristics of the Dobra river during its operation, which is primarily manifested through the occurrence of large water waves. Analyzes also showed that the changed hydrological characteristics affect the geomorphological characteristics of the Dobra River through the increased expansion of the riverbed
