Measurement and analysis of salinization at the Rjecina estuary

A number of salinity measurements were made in the first half of 2012 at the lower reaches of the Rjecina River. The presence of stratified fresh water flow above the salt water wedge was established at the estuary of the Rjecina River. Several regression analyses were made in order to describe functional relationship between the Rjecina flow rate and the salt wedge length. The comparison of measured salt wedge dimensions and the Keulegan semi-empirical expressions is also presented in the paper.Original Abstract: Tijekom prve polovine 2012. godine proveden je veci broj mjerenja saliniteta u donjem toku Rjecine. Pokazalo se kako je u uscu Rjecine prisutno uslojeno tecenje slatke rijecne vode iznad klina slane morske vode. Izradeno je nekoliko regresijskih analiza koje opisuju funkcionalnu vezu protoka Rjecine s duljinom slanog klina. U radu se takoder prikazuje usporedba izmjerenih vrijednosti dimenzija slanog klina s Keuleganovim poluempirijskim izrazima.
