Assessment of the determination of groundwater pollution parameters from destroyed ameliorative structures, tail storage and flooded landfills

Abstract

As a result of the damage to the structures of the supporting front and the destruction of the protective screens on the reclamation systems, tailings storage facilities, and landfills due to military operations, processes of flooding and pollution of water resources are taking place on the territory of Ukraine. This issue requires an assessment and forecast of the further development of events at the damaged buildings. An integral component of such an assessment is the methodology of approaches to the filtration calculations of the consumption of polluted water through a closed protective screen using the analysis of migration due to the aquifer. In this work, the issues of the theoretical approach to the determination of head loss and filtration through a protective screen for the assessment and further forecast of groundwater pollution by filtration flow from tailings, landfills, and reclamation canals due to their flooding due to military actions are considered. Approaches to the determination of pressure loss through a shielded structure in the event of various types of damage and at various stages of water filtration from channels are given. According to the proposed formulas, the loss of water from the main channel of the Ingulets irrigation system and the filtration coefficient of the damaged lining due to the destruction of the dam of the Kakhovskaya Hydro Electric Station were determined. The results of the research will be useful in making management decisions regarding the protection of water bodies from pollution and in the restoration of damaged structures.
