Sažetak
Two natural directions of saline sea water intrusion have been registered in the lower reaches of the Neretva River: the first direction of intrusion is through the Neretva riverbed, and the second one through deeper underground layers. The numerical model of stratified flow is described, and its application in the analysis of the Neretva River salination via the first direction of intrusion is presented. The model is calibrated based on measurements conducted in 2004. It was established that saline water appears in Metković at fresh water flow rates of less than 180 m3/s, while saline water is fully blocked out from the riverbed when water flow exceeds 500 m3/s.
