Abstract

Jezera u gradu Ludbregu su polu-prirodnog nastanka, a u postojećem stanju su obrasla močvarnom vegetacijom uz vidnu eutrofikaciju. U radu je obrađena tema zaštite i upravljanja ludbreškim jezerima te formiranje koncepta za osiguranje dugoročne održivosti upravljanja jezerima. U prvom dijelu rada predstavljeni su mogući pristupi revitalizaciji jezera. U drugom dijelu prikazan je izrađeni hidrološki model za bilanciranje vode u jezerima. Podaci korišteni za proračun bilance su protoci u dovodnom kanalu, količina oborine, gubici od procjeđivanja i gubici od isparavanja. Rezultati proračuna prikazani su u vidu promjena volumena i razine vode u jezerima u vremenu. Rezultati modela pokazuju da model dobro opisuje postojeće stanje jezerskog sustava. Pravilno
održavanje jezera omogućava korištenje jezera u rekreacijske svrhe, ribolov, plivanje i plovidbu, a također pruža stanište za ribe i druge divlje životinje.

Abstract (english)

The lakes in the town of Ludbreg are of semi-natural origin, and in their current state they are overgrown with wetland vegetation and notable eutrophication. The paper deals with the topic of protection and management of Ludbreg lakes and the formation of a concept for ensuring long-term sustainability of lake management. In the first part of the paper, possible approaches to lake revitalization are presented. In the second part, a hydrological model of water balance in lakes is presented. The data used for the water balance calculation are flows in the supply channel, precipitation amount, leach losses and evaporation losses. The results of the calculations are presented in the form of changes in the volume and water level in the lakes over time. The model results show that the model describes well the current state of the lake system. Proper maintenance of lakes allows the use of the lake for recreational purposes, fishing, swimming and sailing, and also provides habitat for fish and other wildlife.
