“…The economic effectiveness of the investment depends on the material types and technology used (Nawrot, 2016) and the effective management of human resources in the construction process (Krynke, 2019). It is also important that building and engineering constructions are resistant to the effects of external factors and ensure the safety of users (Constantin and Nițescu, 2020;Zhelykh et al, 2022;Laghi et al, 2017;Chen and Zhang, 2022). For hydrological structures, safety and risks of those formed in the mountain landscapes of Georgia and calculat-ing the material and economic damage caused by the debris flow should be assessed and the crack has to be assessed in the book by Gavardashvili (Gavardashvili, 2022).…”

Based on theoretical and long-term field researche, the article provides assessment of the management of engineering and technical structures of the Zhinvali hydroengeneering complex. The methodology and quantitative assessment of the risk of loss resulting from accidents at hydraulic structures are described. The implementation of the recommendations of scientific researche related to the protection of the waters of the Zhinvali reservoir will allow to extend its service life for at least another twenty years, which, subject to one-time-only investments in protection measures in the amount of 35 million GEL (1 USA Dollar - 2,90 GEL), will provide an opportunity to bring the amount of direct and indirect loss prevented to 25 million GEL per year. The calculation showed that rational management of the reservoir will allow, with an internal rate of return (IRR) of 42%, to accumulate net present value (NPV) in the amount of 87.6 million GEL over twenty additional years of operation, which in turn indicates a high efficiency of investments in the protection of reservoir waters.

In the context of sustainable development effort, the water supply systems in the rural area of Constanta County should be optimally designed, so that their safe, efficient operation is assured. The results obtained by numerical simulation showed that Movila Verde -Independenta water supply duct might be subject of cavitation occurrence during hydraulic shock. Further investigations showed that the duct is adequately protected by a relatively short closing law of the check valve and three air valves mounted in the nodes where cavitation might occur. Minimal pressure increases from -10 mwc to -0.6 mwc because of these protection measures. Furthermore, the slight increase of maximal pressure does not require additional protection devices.
