Summary: The investigations include the chosen sites in some flysch terrains of the coastal area of the Adriatic Sea and in the aquatorium of the Rijeka Bay. a) The coastal area of the Adriatic Sea. The study of the physical-geological processes including the flysch coastal slope and the flysch terrains of the middle area of Istria. The determination of the erosion intensity of the flysch deposits of the Middle and Upper Eocene by means of the terrestrial photogrammetry. To determine, by laboratory testing, the physical and mechanical parameters of particular lithologic flysch components which are important for erodibility. To compare the erodibility indicators with the results of the repeated measurements by means of phototheodolite. To explain the phenomena and processes in the function of time and climate. b) The aquatorium of the Rijeka Bay. On the coastline and in the submarine zones there are traces of the former sea level stages, i.e. of marking horizon. Their today position allow the conclusion about the vacillation of the sea level during Quaternary. The cognition about the geological structure of the underwater surface has been widened by submarine mapping. The cognitions about the intensity of the marine erosion are possible.

Keywords: physical-geological processes, coastal zone, submarine zone, coastline, sea level, coastal slope, flysch, erosion, intesity of erosion, dinamics of erosion, bioerosion, erodibility, terrestrial photogrammetry, morphogenesis, abrasion, neotectonic movementes, Quaternary, glacio-ustatic oscillations, production of alluvion, Adriatic Sea, Rijeka Bay, middle Istria

Research goals: Aims: the data collecting about the characteristics and dynamicsof some physical-geological processes. The cognition about theintensity of the rocks subjected to erosion, and the quantitativeexpressing of the erodibility of the particular lithologicalflysch component. It can be used as the basic measure for rankingother rocks. By the repeated prospecting of the same motives byterrestrial photogrammetry in somewhat longer period todetermine, by instruments, the intensity and dynamics of erosionand the deficit of the rock mass in time. To improve the methodof the terrestrial photogrammetry in order to become the standardone for observing the erosion. To determine the influence of theclimate changes, glacio-eustatic oscillations of the sea-waterlevel and neotectonic movements through Quaternary in theaquatorium of Rijeka. To find out the influence of the change ofthe erosion base on the hydrogeological relations and thecarsting intensity in space and time. Results and the expected contribution: Gaining the cognition inthe field of "engineering geodynamics". Practical application inwater resources management, agriculture, forestry and harbour engineering.
