Summary: Alluvial, transitional, and shelf sediments in the coastal Dinarides show features characterizing coarse-grained systems with high sediment supply, transversal basin infill, and the combination of internal and external factors of their development. Depositional processes responsible for the origin of sandstones in so-called flysch zone revealed shallow-marine environments. Dinaric foreland basin received detritus from a southern shelf. The existence of marine connections between Mediterranean and Pannonian realms has been confirmed. All-void-rimming speleothems are excellent stratigraphic marker. Provenance study provided data on detrital character of numerous mineral grains in platform carbonates in contrast to previous knowledge. This work has contributed to the knowledge of the dynamics of the critical and mobile land/sea interface by studying recent and fossil examples. Recent karstic river mouths were identified as the object of the primary interest. A modification of a global classification of estuaries was proposed, with Raša River estuary as a type model for a "disequilibrium river-dominated estuary". The role of natural processes of transport and sedimentation of fine-grained riverborne particles in the fate of contaminants at the river/sea boundary was particularly studied. Methods included the analysis of facies parameters, recognition of sedimentary processes and genetic sequences, comparison of recent and fossil environments, and analysis of the facies geometries and relationships. Techniques included a variety of field and laboratory procedures and analyses.

Research goals: The purpose of the study of the Paleogene coarse-grained alluvium is to explain their organisation, as well as the influence of internal and external factors on their evolution. The results will also help in understanding of the most critical period in the evolution of coastal Dinarides of Croatia. Some sandstones usually ascribed to "flysch", show features indicating shallow-marine environment, and this inconsistency needs explanation. It is aimed to explain the provenance of the shelf material occurring in the Istrian flysch and possible marine connection with the Pannonian Realm. It is also aimed to find out indications of depositional environment of Tuzla evaporites. The origin of all-void-rimming speleothems will be explained. The study of provenance will provide data on the origin of non-carbonate component in Dinaric platform carbonates. The aim of investigation of recent river mouths debouching into low-energy seas is to understand better the fate of riverborne suspended matter at the freshwater/seawater interface and the factors contolling distribution of terrestrial particles in river mouths and shelf. This work should contribute to the understanding of fate and role of fine-grained riverborne particles in accumulation of contaminants in low-energy seas. The work will concentate on evolution, morphodynamics, and classification of river mouths. These results will help in the interpretation of fossil river mouth systems. It should also contribute to the understanding of the impact of natural and man-made dams on processes at river mouths.
