The chapter provides information on crop evaporation and water consumption during different growth stages, influenced by prevailing weather and climate conditions. This data serves as the basis for designing and implementing effective water regulation strategies. The authors conducted an assessment of the weather and climate in Western Polissia of...
Developing a predictive system for water deficit analysis in the Black Sea Lowland, especially in climate change, involves integrating various data sources, modeling techniques, and technological tools to forecast water availability and demand. The analysis of the change in moisture deficit in the Kherson region is provided for the period from 1955...
The forecast data on the impact of changing weather and climatic conditions on evaporation, water demand, and crop yield on drained lands in Western Polissia of Ukraine at different stages of their development are presented. They serve as the basis for creating the project water management regimes and forming the operational water management regime...
The research results on creating information materials for assessing the impact of modern climatic factors on the formation of soil water regimes on drained lands are presented. By the results of the research, carried out at the "Romen" drainage and irrigation system (Sumy region), it was established that over the past 34 years, the average air tem...
In this work, after electron irradiation and X-ray, the outcomes of the evaluation dynamic characteristics of interstitial atoms Si j , vacancy V , and O -complexes were evaluated to account for the annealing conditions to derive specific structural defects in the SiO 2 /Si wafer. A non-destructive method, which allows the determination of the inte...
The environmental state of rice irrigation systems (RIS) is determined by many factors, including natural ones (soil, topographical, hydrogeological, and climatic factors) and technological ones (irrigation norm, design, and parameters of irrigation and drainage networks, etc). The most significant influence on the ecological reclamation state of t...
The results of analytical and field studies of the influence of modern climatic conditions on the formation of the soil water regime on drained lands are presented. It has been determined that an increase in air temperature and uneven distribution, changes in the nature, intensity, and structure of precipitation, and an increase in the number of ca...
Modern agricultural production is under the direct influence of climatic changes, which is also reflected in the water regime formation of the soil during the cultivation of crops. Calculations were made and graphical materials were created for average daily, average decadal, and average monthly values of temperatures and the amount of precipitatio...
The simultaneous influence of hydrogen H and ultrasound deformation on internal friction Q ⁻¹ and dynamic elastic modulus E of intermetallic Ti 3 Al alloy after cutting and polishing were studied. The relaxation maximum of internal friction Q ⁻¹ M1 at temperature Т М1 ≈ 398 К, conditioned by the mechanism caused by reorientation interstitial atoms...
The paper discusses the results of theoretical studies aimed at the development of new methods and means of preventing dangerous states and failures in complex technical systems. Moreover, the research considers the conditions of unclear input information and stochastic uncertainty presented using the theoretical provisions of the theory of stresse...
This chapter considered qualitatively different approaches to the water regime model of drained lands implementation. The fundamental difference of these approaches is that the regime forecast calculations on a long-term basis are performed for schematized natural reclamation conditions by typing meteorological regimes in the calculation periods of...
In modern conditions of climate change and agricultural use of drained lands, there is a need for efficient production with the introduction of new or improved technologies for growing economically attractive crops that can ensure sustainable harvests, environmentally safe production, and minimize all costs, including water resources. By implementi...
The necessity and the basic directions of the scientific vision of further reforming the systems of water resources and land reclamation management are determined. The need for such a reform is dictated by the fact that, despite the adoption on October 4, 2016, by the Verkhovna Rada of Ukraine of the Law "On Amendments to Certain Legislative Acts o...
The waste warm waters from power plants, owing to their temperature regime (25–38°C) and the volumes of discharge, allow for their use for heating of open ground areas in agriculture. Underground heating by such water is a new, special heat and irrigation method which enables not only purposeful regulation of temperature conditions of the crop grow...
One of the rational ways of energy saving is to use the heat of wastewater from energy companies for open ground heating and cultivation crops. The most significant sources of heat are thermal and nuclear power plants that produce low-thermal waters of 28–35°C. Heating of the ground with the use of circulating warm water allows to increase temperat...
The paper focuses on research on improving the water supply of drainage systems of humid areas in the context of anthropogenic climate change. The aim of the research is to elaborate on the ways for increasing the available water supply of drainage systems and restoring active water regulation on reclaimed lands in a changing climate. Reclaimed lan...

The article substantiates the necessity and considers possible approaches to the system optimization of technological and constructive parameters of polder systems as a necessary condition for the creation and functioning of water management and reclamation facilities on ecological and economic bases under changing climatic conditions.
The theoretical bases of the method of multi-criteria parametric optimization are developed, algorithms of calculation of continuous systems with typical linear regulators are given. Algorithms of the calculation of systems with digital controllers are given and shown on the example of the calculation of system with digital PI- regulator and object...
The approach to construction of systems for estimating the residual resource of safe operation of complex technical constructions is proposed, including the construction of a mathematical model of the functioning of the structure for determining its actual state and residual resource.
This work is aimed at finding possibilities for increasing the accuracy of measurements and interfering analog interfaces for remote measurements using resistive strain gauges by introducing a new structural scheme, which is shown on the Fig. 1. It shows us the Schematic of the electrical functional analog interface for remote measurement using mul...
Nowadays the most common instruments of measuring the stress-strain state of complex structures are strain gauges. As a rule, strain gages are connected to the measuring system according to the bridge scheme, it provides elimination of systematic errors of measurement and compensation of temperature deformations. The principles of constructing, des...
