Sažetak
The Baška beach, one of the largest gravel beaches in Croatia was monitored over 3 years. This paper presents analysis of the shoreline position derived from these measurements. The shoreline position and the beach width were calculated from beach profile measurements. Overall changes in shoreline positions were quite small except in areas affected by fresh- water input (stream and urban runoff) and near a groyne. Several storm events were covered during the observation period. In most of these cases, the shoreline retreat was registered as expected. This would be followed by a rapid beach recovery and resulting shoreline advancement. After NE (Bura) storm wind event the shoreline advancement was registered. However, the close inspection of the beach profiles showed that this registered shoreline advancement was due to accumulation of sediment at the toe of the beach. This material was eroded at the upper beach. This finding and the lack of beach rotation indicate that the cross- shore sediment processes dominate during the energetic events
