Abstract
Tema ovog rada su prodori morske vode u riječna korita. Prikazana su istraživanja na tri hrvatske rijeke Neretvi, Jadru i Rječini. Primjeri zaslanjivanja korita rijeke Neretve prikazani su pomoću numeričkog modela stratificiranog strujanja. Pri analizi zaslanjivanja ušća rijeke Jadro, primijenjen je identičan model kao i u slučaju Neretve, a u proučavanju procesa zaslanjivanja ušća Rječine korištena je regresijska analiza. U uvodnom dijelu rada opisan je utjecaj rijeka na more, podjela estuarija i zaslanjivanje riječnih ušća općenito. Utvrđeno je da u području donje Neretve postoje dva prirodna pravca prodora slane morske vode: prvi, kroz korito rijeke Neretve, te drugi kroz duboke podzemne slojeve. Prikazan je i opisan model stratificiranog strujanja te je primijenjen za proračun zaslanjivanja rijeke Neretve. Kvalitetan uvid u procese zaslanjivanja ušća rijeke Jadro dobiven je primjenom numeričkog modela za različita hidrološka stanja. Istraživanja Krvavice i sur. (2013) pokazala su da je u ušću Rječine prisutno stratificirano strujanje slatke riječne vode iznad klina slane morske vode. Izradili su nekoliko regresijskih modela koji opisuju funkcionalnu vezu protoka Rječine s duljinom slanog klina i dubinom razdjelnice slojeva.
Abstract (english)
Subject of this work is intrusion of the saltwater into the river estuaries. Investigations conducted on three rivers: Neretva, Jadro and Rječina, are shown. The examples of salinization of Neretva riverbed are shown using the numerical model of the current flow. The same model applied for Neretva estuary, was also used for Jadro River, whereas salinization of the Rječina is described using regression analysis. Introduction describes influence of rivers on the sea, types of river estuaries and salinization of river mouths in general. Two natural pathways of salt water in the lower parts of Neretva River are discovered: the first one, through the Neretva riverbed, and the second one through deep underground layers. Model of the current flow and its application for the Neretva intrusions is described. Application of the same numerical model for different hydrological conditions, resulted in high-quality insight of salinization in Jadro River. Investigations conducted by Krvavica et al. (2012) reveal flow of fresh water above wedge of salt sea water in the lower part of Rječina River. Several regression analyses were made to describe functional connection between the Rječina flow rate and the salt wedge length.
