Abstract

The Raša River valley and its estuary are located on the eastern part of Istrian peninsula (north-eastern coast of the Adriatic Sea). Intensive sedimentation in microtidal estuary environment started due to a lowering of sea level during the Holocene. Most of the sediments were brought over by erosion of Paleogene flysch rock mass on the uperstream catchments area and Quaternary deposits from the ancient Čepić Lake. Slow sea level rise during the last 6.000 years created the conditions for filling the earlier formed karstic estuary. Because of intensive sedimentation the mouth of the Raša River was shifted for approximately 4 km in the last 240 years. The sediment body has uniform granulometric composition,
