Abstract:
An approach is presented that allows to choose the facilities of geoengineering protection of accumulated environmental damage. This approach is based on taking into account the peculiarities of the hydrogeological, hydrological, geomorphological situation of territories where the objects are located, as well as their ranking depending on the environmental burden. A practical example of arrangement of a large storage of hazardous waste of the chemical industry is considered. Such protection with a perimeter waterproofing curtains combines the anti-filtration functions, bank protection and stre

Abstract:
The possible scale and degree of contamination of groundwater in the areas of sludge storage of alumina plants were estimated and patterns of changes in the composition of groundwater were established. The zone of intensive impact of the sludge storage on groundwater has been determined. A set of environmental measures has been developed, providing for the creation of a contouring anti-filtration curtain, pumping of contaminated groundwater by drainage wells, carbonation of sludge waters in order to reduce pH and transfer harmful impurities into insoluble compounds.

Technological solutions for the construction of sludge barns at the Pereschepynskoye deposit are considered and analyzed. The authors proposed to arrange a monolithic vertical anti-filtration curtain of the type "wall in the soil" of soil-cement elements. When filling the sludge storage, it is proposed to fill with waste using the following technology: pour a layer of waste about 1 m thick on the bottom of the sludge storage, then pour a layer of soil on top of the construction site (humidity 4-5%) up to 1 m. drying it is offered to add ash of removal of the Mykolaiv thermal power plant.

Abstract:
Introduction. Storage facilities, designated for the toxic production waste and located on the premises of the former Sredne-Volzhsky chemical plant in Chapayevsk, Samara Region, are sources of negative environmental impacts. The situation is aggravated by the lack of a reliable seepage prevention circuit at toxic waste storage facilities, enclosed by natural impermeable layers. The purpose of the study is to substantiate the choice of the optimal base for seepage prevention curtains along the perimeter of toxic waste storage facilities by clarifying the filtration characteristics of imperviou

Abstract:
When designing structures made of sheet piles, it is often necessary to evaluate their filtration characteristics. The base material of the tongue is waterproof, however, groundwater filtration is carried out through special lock joints. The publication considers the procedure for experimental determination of the filtration coefficient of locking joints of sheet-pile fences made of polymer composite profiles based on the results of laboratory tests. Considering the mathematical model of filtration processes, it is based on a modified empirical Forchheimer dependence generalizing nonlinear fil

Relevance of research. In the course of the operation of irrigation systems, there is a need to protect the hydraulic structures and the adjacent territories from filtration, which should be considered as a separate type of harmful effects of water. Filtration of water from canals and ponds leads to secondary flooding, salinization and waterlogging. Filtration of water at earth dams under certain conditions leads to the destruction of dams and the creation of emergency zones in the surrounding territories. In today's conditions of reforming the Ukrainian economy, it is particularly important t

Abstract:
Polyethylene is the most common material of films used in hydraulic construction. In the process of construction of hydro technical structures, rolled polyethylene film, manufactured in factory conditions, is connected into continuous anti-filtration structures: screens, diaphragms, curtains. A reliable method of joining the edges of polyethylene film is welding. But in some cases, for example, during the construction of anti-flood dams with anti-filtration diaphragms using a high-performance trenchless method of laying rolled polyethylene film in the soil, there is a need to use a more conven

Дисертація присвячена підвищенню рівня екологічної безпеки урбанізованих територій, що зазнають підтоплення ґрунтовими водами, за рахунок наукового обґрунтування методів та засобів прогнозування та управління підтопленням. Підтоплення територій не тільки негативно впливає на життєдіяльність населення, а і може привести до виникнення екологічних катастроф та значних матеріальних збитків. Вперше розроблено крайові умови математичної моделі зміни рівня ґрунтових вод, що враховують вплив штучних покриттів поверхні ґрунту і евапотранспірацію для вдосконалення прогнозів та управління рівнем ґрунтов
