Abstract

Promjene unutar vodnih sustava utječu na promjene režima nanosa u vodotocima. Tako nastala pojava neravnoteže može za posljedicu imati povećan rizik od poplava, smanjenje mogućnosti plovidbe i proizvodnje električne energije na vodotocima te može pogodovati degradaciji ekosustava i smanjenju biološke raznolikosti. Iz toga razloga, potrebno je vršiti redovita mjerenja i praćenja režima nanosa. Unutar ovog diplomskog rada obrađene su osnovne karakteristike vučenog nanosa i prvi modeli procjene njegove količine u vodotocima. Zatim podjele najprimjenjivanijih i najučinkovitijih metoda njegova mjerenja danas. Opisani su osnovni principi i alati za provođenje takvih mjerenja. Nadalje su istaknute prednosti, mane i ograničenja pojedinih metoda te njihova usporedba. Na kraju rada iznijete su preporuke o korištenju metoda mjerenja vučenog nanosa na hrvatskim rijekama.

Abstract (english)

Changes within water systems affect sediment regime in watercourses. The resulting imbalance may result in an increased risk of flooding, reduced navigability and electricity production and may be indicative of ecosystem degradation and biodiversity loss. For this reason, it is necessary to perform regular monitoring and measurement of the sediment transport. This master thesis discusses the basic characteristics of bedload sediment transport and the initial models for estimating its quantity in watercourses and effectivness of the methods of its measurement up to date. The basic principles and equipment for conducting such measurements are described. Furthermore, advantages, disadvantages and limitations of individual methods are highlighted, and their comparison. At the end of the paper, recommendations on the use of methods for measuring bedload transport in Croatian rivers are presented.
