Summary/Abstract: The main objective of this paper is to reconstruct Holocene evolution in four neighbouring catchments in the Eastern Adriatic coast (Croatia). Marine geoacoustic geophysical survey was paired with high-resolution multiproxy analysis (chemical analysis, grain size, magnetic susceptibility (MS), L*a*b* spectrum, C/N analysis, bulk XRD analysis, AMS 14C) of four long marine sediment cores at Zrmanja river mouth, Novigrad Sea, Karin Sea and Modrič bay together with fifteen soil sediment cores or profiles sampled in their respective catchments. This data enabled us to create palaeo-environmental reconstruction of the Holocene sediment sequence and partially of underlying Pleistocene sediments in the Novigrad and Karin Sea. During the early Holocene surface of today’s area of Novigrad and Karin Sea hosted river channels incised in Pleistocene clastic rocks. Multiple channels suggest the existence of braided river system. Three marine sediment cores penetrated marine sediment sequences and terminated in sediments predating the Holocene sea level rise. Assemblage of foraminifera (or their absence) in sediments indicates alluvial/colluvial/beach sediments.
