Clarification of hydrological regime and ecological parameters in the Georgian Black Sea coastal zone using mathematical modeling and experimental methods.
2024
The expected intensification of human economic activity in the Black Sea coastal zone of Georgia in the coming years makes scientific research and forecast of ecological state and dynamics of coastal waters very relevant. The aim of the present work is to study some features of local circulation and thermohaline fields in the coastal waters of Georgia based on mathematical modeling and quantitative assessment of the main ecological parameters through experimental research. Mathematical modeling is based on the regional baroclinic model of the Black Sea dynamics, which provides the calculation of 3D hydro-physical fields – the current, temperature and salinity with a spatial resolution of 1 km in the Georgian sector of the Black Sea. The assessment of ecological parameters is carried out on the basis of field-scientific studies conducted in the Georgian water area and laboratory analysis. Quantitative indicators of seawater acidity and salinity were determined at 35 sensitive points along the 110-km coastline of the Black Sea, including the estuaries of major rivers, seaports, and oil terminals. Also, quantitative indicators of heavy metal pollution were determined in laboratory conditions, the values of which were found to be less than the permissible concentration. Tab. 2, Fig. 3, Ref. 17.
