On river plumes along the Turkish coast of the black sea

Heavy rains have become a serious problem for the coastal zone of the Krasnodar Territory of the Russian Federation and the Black Sea coast of Turkey. They lead to a significant increase in water levels in rivers, flooding of villages and even large cities, damage to urban and tourist infrastructure, roads and railways, bridges, beaches, flushing of garbage and sewage into rivers. This leads to environmental problems and even loss of life. River runoff forms river plumes in the coastal zone of the sea, which, depending on wind speed and direction, speed and direction of coastal currents, river runoff and density difference with sea water, can have various forms and spread in different directions from the mouth of the river, as well as participate in mesoscale and sub-mesoscale circulation of coastal waters. River plumes significantly affect the quality of sea water and the sanitary and epidemiological situation on the beaches of the resort area of Krasnodar Territory and Turkey. The situation is aggravated by the fact that sewage systems are in poor condition in cities or are completely absent in most of small villages along rivers and the coastal zone. After heavy rains, wastewater very often reaches the sea and poses a serious threat to human health. The purpose of this study is to use satellite remote sensing to demonstrate the behavior of river plumes along the Black Sea Turkish coast. © 2019.13/1251/2018 Ministry of Science and Higher Education of the Russian Federationsupported by the Ministry of Science and Higher Education of the Russian Federation at the Lomonosov Moscow State University, and by the Fund of the National Technological Initiative dated December 11, 2018, No. 13/1251/2018
