Sažetak
This paper examines sediment transport, sedimentation and properties of suspended matter and sediments in the Raga River estuary, a small, rock-bounded, microtidal, low-wave-energy karstic estuary in the north-eastern Adriatic. The Raša River is characterized by large variation in water flow and variable load of mineral particles. More than 90% of this load is brought into the estuary as fine-grained suspended matter, consisting of only 24-36% of carbonates, the rest being clays. Sedimentation occurs at the salt wedge, resulting in a progradation of estuarine delta. Salt-induced flocculation is the predominant process of sediment deposition. The Raša estuary is infilling with sediment, and classifies as a disequilibrium estuary. We propose a modification of Cooper’ s (1993) classification scheme to include river-dominated, disequilibrium estuaries, with the Raša River as an example
