Sažetak

Effluent transport in the aquatic environment can be described by using very complex mathematical formulations that include the most relevant processes and their unsteadiness and non-uniformity. This paper gives some evidence of the capability and importance of numerical modelling implementation in the analysis of effluent transport, following the discharge from sewerage submarine outfalls. Numerical models Cormix, Mike 21fm, Mike 3fm and ROMS are described in brief and applied to a particular example in the vicinity of the city of Poreč. Five separate sewerage systems and associated submarine outfalls were encompassed within the numerical model spatial domain: Lanterna, Červar-Porat, Poreč north, Island Sv. Nikola, Poreč south, Petalon i Koversada. Two scenarios of effluent treatment and discharge are modelled that represent the present and the future-planned state according to the development concept project. Positive aspects from the planned activities are obtained through comparison between the faecal coliforms concentration dynamics.
