摘要：Sea resort areas are currently one of the most successful developing regions. At the same time, the ecological condition of such regions is important, especially those that specialize in the provision of recreational and tourist services. The quality of coastal water resources played an important role in the sustainable development of those coastal tourist areas. Analysis of physical factors of water exchange was carried out and assessment of water resources quality of the coastal zone of the sea was made, including in closed and semi-enclosed water areas. It has been shown that water exchange is the most important factor in the management of the quality of marine waters of partially enclosed coastal areas. The results of the studies made it possible to assess the circulation of coastal marine waters and the change in certain indicators of water quality, including in the presence of various coastal protection facilities, based on 0-dimensional and system-dynamic models. The results obtained can be used to predict the state of water resources in coastal territories.
