Summary: The purpose of this fundamental project is to develop a digital simulation method for investigation of the fate of solutes in natural waters. The investigation of the sorption of solutes on solid-liquid interfaces (for example on surfaces of suspended partices and sediments) and complexation of micro-constituents in water with natural organic macromolecules as ligands will have the priority in such investigations. In both cases the interaction of solutes with large number of different active sites with a whole variety of different binding strengths takes place. The results of such fundamental investigations will be incorporated in the development of digital simulation of the transport and the fate of pollutants in ground waters of the Sava river aluvium in the environment of the city of Zagreb. Through additional projects special measures will be designed for the protection of water sources and improvement of water supply for the city of Zagreb. Land based sources of pollution of the Adriatic sea in the Republic of Croatia will be estimated including all anthropogenic and natural sources. Anthropogenic sources include all sewage water of households and industries, while natural sources include precipitation and river inputs.

Keywords: digital simulation, dispersion of solutes, ground water, Sava river, sorption, complexation, suspended particles, sediments, organic matter, microconstituents, binding strength

Research goals: The purpose of these investigations is to develop digital simulation of physical and chemical processes in natural waters and at geological and biological (solid/liquid) interfaces. To this purpose the results of laboratory, field and remote sensing investigations should be used. By the application of digital simulation the mechanisms of homogeneous and heterogeneous chemical reactions taking place in natural waters and at geological and biological (solid/liquid) interfaces under the influence of mass transport will be investigated. Application of new knowledge about such processes can enable interpretation of laboratory, field and remote sensing investigations. On the basis of these investigations the prediction of physical and chemical processes in natural waters and at geological and biological (solid/liquid) interfaces will be performed. For succesful performance of these investigations the collaboration with water works development projects is very important. The amount of waste waters from heterogeneous sources and their input to the sea will be estimated. The analysed pollutants will include nutrients, hydrocarbons and heavy metals. The results could be used for estimation of the recieving capacity and for the improvement of the regional planning and management.
