MODERN METHODS OF HYDRAULIC CALCULATION OF LINEAR AND POINT RAIN-RECEIVING ELEMENTS.

The relevance of the article is due to the importance of the problem of water drainage at modern construction sites. When designing buildings and structures, it is necessary to take into account the possibility of efficient collection and drainage of water from the surface of the roof and the territory. The goal is to represent relevant information about the methods of hydraulic calculation of rainwater elements used in modern engineering practice. Among the methods used in the research, the analytical method, synthesis method, functional method, deduction method, and other approaches were used. The scientific and practical task related to the development of new and improvement of known methods of modelling rain run-off in built-up areas, taking into account the regulatory influence of individual elements of water drainage structures, is being successfully carried out. The results of this study are very important for ensuring the reliability of water drainage systems in the settlements of Ukraine, especially under the conditions of the growth of urban development and changes in climatic conditions. To develop practical surface run-off management plans, it is necessary to scientifically model the run-off level, taking into account the climatic characteristics and parameters of the run-off basin, as well as the predicted changes over time. The task of modelling the behaviour of surface run-off in urbanized areas is complex and it contains many factors. The study shows that reliable modelling results of complex rainwater drainage systems with regulating facilities can be obtained only with the help of multifactorial and multistep models implemented with the help of computer programs. The practical value of the research is that it helps to improve the design and operation of water drainage and water supply systems. [ABSTRACT FROM AUTHOR]
