Development of the Ecological Models of the Adriatic Sea

Numerical ecological modelling is relatively new approach in Croatia for determination of ecological state of the Adriatic Sea. In this article a description of numerical ecological modelling implemented in scientific– professional Project The Adriatic Sea Monitoring Program has been presented. The main goal of the Project is to make an expert assessment of the currently sea monitoring system and its compliance with the provisions of the EU Water Framework Directive (2000/60/EC). This article gives short insight in scope of works of The Adriatic Sea Monitoring Program related with in-situ physical, chemical and biological oceanographic measurements, numerical modelling implementation and its results. Oceanographic measurements for the first six months of the Project were performed in the eastern part of the Adriatic Sea at 20 current meter and CTD sites, 46 sites occupied with all measured parameters, 16 CTD sites and 2 waverider sites. For the numerical modelling, four renowned numeric systems (ROMS, POM MIKE 3 and MIKE 3 FM) were utilized. ROMS and POM were used for the hydrodynamic analysis on the whole area of Adriatic Sea. The results of that analysis are used for the boundary conditions for MIKE 3 and MIKE 3 FM at 8 (MIKE 3) and 5 (MIKE 3 FM) unfolded spatial domains. For numerical analysis of the spatial and temporal dynamics of the dissolved oxygen (DO), faecal streptokok (FS) and faecal coliform (FK ) concentrations MIKE 3 FM and MIKE 3 EcoLab module were used. Finally, results of measurements and modelling were presented as well as their comparison. It has been concluded that very good agreement between measured and modelled values were obtained.
