Abstract

Numerical modeling of the distribution of floating marine debris in the coastal waters of the Black Sea of Georgia using marine litter monitoring data is presented. The monitoring was carried out in Poti and Batumi nearshore water areas during September 2019 under the framework of EU project RedMarLitter. To simulate floating marine debris a 2D nonstationary advection-diffusion model is used, which is coupled with the regional model of the Black Sea dynamics of Institute of Geophysics of I. Javakhishvili Tbilisi State University (RM-IG), The RM-IG is a core of the regional forecasting system for the easternmost part of the Black Sea and is based on a full system of ocean hydrothermodynamics equations written in a Cartesian coordinate system. The modeling results showed the important role of advection and diffusion processes in the spatial-temporal distribution of floating solid waste.
