Ecological and economical consequences of catastrophic floodsand their supplements of the Dnister engineering and environmental field

The article deals with the creation of Dniester’s scientific-educational-production engineering environmental flood landfill (DSEPEEF) was created in 2012-2018 after a catastrophic flood on July 23-26, 2008 on an area of 1460 km2 in the upper reaches of the Dniester River. The uniqueness of the landfill is that it is the only territory in the Western region of Ukraine, where in the closed hydrological system combined pools of inflows - the Dniester tributary, which makes it possible to calculate the balance between precipitation and their consequences - costs, the height of water rise and the time of its arrival at that or other territory of the Dniester valley. To increase the level of ecological safety of territories at risk of flooding by catastrophic floods on the basis of theoretical, methodological, experimental and practical research: developed a detailed methodology of GIS to assess the ecological status and ecological situation of natural anthropogenic geosystems affected by catastrophic floods; the stage of catastrophic floods was established according to the geomorphological levels of floodplain terraces and the first floodplain terrace, which makes it possible to zonate the territories of settlements according to flood risk; theoretical bases of the automated information-measuring flood control system are offered
