COST EFFECTIVE ADAPTATION TO CLIMATE CHANGE AT THE COMMUNITY LEVEL IN UKRAINE

At the beginning of the 21st century, when it became clear that humanity would feel the effects of climate change mainly through waiter, research of the Institute of Mathematical Machines and System Problem of the National Academy of Sciences of Ukraine which modelled the spread of the Chernobyl disaster consequences in the aquatic environment, was also aimed at water modeling of the adaptation to climate change in Ukraine. The article shows how mathematical modeling of water resources can help develop the most cost-effective proactive adaptation measures at the community level - early warning of communities about extreme weather and reducing the impact / consequences of extreme floods.
