The article presents forecast data on the impact of changing weather and climatic conditions on evaporation and water demand on the drained lands of Western Polissia of Ukraine in different periods of their development. These data are the basis for the development of appropriate adaptive measures aimed at reducing the negative impact of changing we...

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...

The existence and structure of the hierarchical and hydraulic relationship between the parameters of soil flow movement, the parameters of the closed collector-drainage network, and the parameters of channels and structures of drainage systems based on the application of the system methodology were determined. A physical model, a structural model,...

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 need for further development of irrigation practices on the basis of nature oriented and ecologically efficient solutions is considered primarily regarding the saving of water and energy resources for the adaptation of irrigated agricultural production to the current global challenges and threats, the achievement of sustainable development goal...

A system optimization method was used, which consists in the consistent justification of optimal technological and constructive solutions and parameters of drainage polder systems during the development of their projects. This is done in compliance with modern economic and environmental requirements according to criteria and models for di erent lev...

This paper presents the need and scientific-methodical approaches to improving the calculation of the closed collector-drainage network of water discharge systems.

Представлено теоретичні дослідження коефіцієнта гідравлічного опору в трубах з однорідною зернистою шорсткістю. Результати дадуть змогу удосконалити залежності для практичних розрахунків трубопроводів.

The existing problems of energy, water, and food crises and climate changes determine the need to implement appropriate adaptive measures to improve the ecological and reclamation state of drained mineral soils. For the application of deep loosening of the soil as an adaptive agromelioration measure, a transition from traditional crack loosening of...

The paper presents a new approach to improving the methods of design and calculation of drainage systems and their technical elements in the drainage mode and in the subsoil moistening mode. This was done on the basis of substantiating the connection of all technical elements of the system and taking into account the influence of their work efficie...

The necessity and scientific and methodological approaches to improving the calculation of a closed collector-drainage network of drainage systems are considered. Based on the application of the system methodology, the structure of the hierarchical and hydraulic connection between the water regime of the field and the operation mode of the closed c...

Based on the analysis and generalization of the data of domestic and foreign scientists and specialists, as well as the results of the authors' respective research, an assessment of the current state of changes in weather and climatic conditions in the Polesie zone and their impact on agricultural production, fertility, and moisture supply of soil;...

This chapter provides an analysis of the results of long-term research on the peculiarities of the geographical location and origin, the specifics of formation and existence, the characteristics of the hydrographic network, and the climatic and weather conditions of Polesie. The chapter presents the analysis of the results of many years of research...

Research relevance. Climatic changes determine the need to ensure a high productivity of drained lands through the use of appropriate adaptive measures for regulating and accumulating moisture in the soil. Therefore, the issue of changing approaches to the creation and operation of water reclamation facilities on drained lands gains relevance. Rele...

The paper presents the disclosure of the problem of calculating the friction factor. This problem exists in the calculations of head losses for a given flow discharge and the geometric parameters of the pipes. The analysis of the formulas recommended by known scientists is described. The article also presents the shortcomings of the formulas and th...

Land reclamation is important in the development of agricultural production for unfavorable climatic conditions. This necessitates the improvement of scientific and methodological approaches to the creation and operation of water management and reclamation facilities, including drainage systems, which are adapted to these changes. Approaches to the...

The article consideres the analysis of the literature about the development of the water turbulent flow theory in the pipes. According to the results of analysis and theoretical studies, we obtained mathematical models. These models described the kinematic structure of the water turbulent flow in the pipes for different regions of turbulence. For t...

We have analyzed various methods and models for determining and calculating drainage module. The drainage module is an important indicator of the hydrogeological effect of drainage and soil drainage. For the calculation of the drainage calculation module, an empirical, analytical, water-balance method is used, or it is accepted on the recommendatio...
