Sierikova O. The groundwater level forecasting and management for increasing the ecological safety of the built up territories of Ukraine

Thesis treats the environmental safety improving of urban territories flooded by groundwater through the scientific substantiation of methods and technics of flood forecasting and management. For the first time, the boundary conditions of the groundwater level changing mathematical model have been developed. Mathematical model takes into account artificial coverings on the soil surface and groundwater discharge processes due to evapotranspiration to improve predictions and management of groundwater level on the built-up areas. The forecast of maximum groundwater level rise variant in natural and technogenic geosystems conditions of large cities has been developed on the Kharkiv city example. Scientifically has been grounded and experimentally established a period with the smallest natural factors manifestation for the value detection of technogenic additional groundwater replenishment. The engineering measure has been proposed for the roadbed protection from the groundwater harmful effects, which involves the installation of the anti-filtration curtain along the highway. The flood prevention system has been developed and specificated, includes typical scheme of the management functions and tasks for preventing and mitigating the flooding consequences, the actions algorithm during groundwater levels monitoring in flooded and potentially flooded areas, and the Project of measures set to prevent the flooding of urban areas in large cities of Ukraine on the basis of European experience.
