Numerical Modelling of the Circulation and Pollution Transport from Rivers and Wastewater Treatment Plants in the Sochi Coastal Area

摘要

This paper provides a brief description of the technique for simulation Black Sea circulation and pollution spreading in the Sochi coastal area. Two versions of the ocean circulation INMOM model are used: Ml model with coarse spatial resolution of 4 km and M2 model with non-uniform spatial resolution. Large-scale structure and mesoscale large eddies of Black Sea are simulated using Ml model. M2 model is applied for simulating mesoscale and sub-mesoscale dynamics, in addition to simulating large-scale structure of the Black Sea circulation in the coastal zone near Sochi. In this study we analyse the structure of horizontal and vertical coastal currents and estimate concentration and spread of pollution. The results of numerical modelling in the coastal zone were successfully validated using laboratory and observation data from Elkin et al., 2017.
